Tropical Storm Nicole Brings Wind and Rain to Northwestern Bahamas

Tropical Storm Nicole brought wind and rain to the Northwestern Bahamas on Wednesday afternoon. At 4:00 p.m. EST on Wednesday the center of Tropical Storm Nicole was located at latitude 26.5°N and longitude 77.9°W which put it about 135 miles (220 km) east of West Palm Beach, Florida. Nicole was moving toward the west at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 985 mb.

A Hurricane Warning was in effect for the portion of the coast from Boca Raton to the Flagler/ Volusia County Line, Florida. The Hurricane Warning included West Palm Beach, Ft. Pierce, Melbourne and Daytona Beach. A Hurricane Warning was in effect for the Abacos, Berry Islands, and Grand Bahama Island. A Hurricane Watch was in effect for the portion of the coast from the Boca Raton to Hallandale Beach, Florida. A Hurricane Watch was in effect for Lake Okeechobee. A Tropical Storm Warning was in effect for Bimini. A Tropical Storm Warning was in effect for the portion of the coast from Hallandale Beach to Boca Raton, Florida. A Tropical Storm Warning was in effect for Lake Okeechobee. A Tropical Storm Warning was in effect for the portion of the coast from the Flagler/Volusia County Line, Florida to the South Santee River, South Carolina. The Tropical Storm Warning includes Jacksonville, Florida and Charleston, South Carolina. A Tropical Storm Warning was in effect for the portion of the coast from Bonita Beach to Indian Pass, Florida. The Tropical Storm Warning included Tampa and St. Petersburg.

The center of Tropical Storm Nicole passed over Great Abaco Island in the Northwestern Bahamas on Wednesday. The center of Nicole’s circulation was just to the southeast of Grand Bahama Island on Wednesday afternoon. The inner end of a rainband wrapped completely around the center of circulation. An eye with a diameter of 30 miles (50 km) formed at the center of Tropical Storm Nicole. Bands of showers and thunderstorms were revolving around the core of Nicole. Storms near the center generated upper level divergence that pumped mass away from the tropical storm. The removal of mass caused the surface pressure to decrease at the center of circulation.

The strongest winds were occurring in the northern side of Tropical Storm Nicole, but the overall circulation was very large. Winds to tropical storm force extended out 480 miles (775 km) from the center of Nicole’s circulation. Stations along the east coast of Florida reported sustained wind speeds of tropical storm force on Wednesday afternoon. Electricity outages were reported in several areas. Northeasterly winds were pushing water toward the coast and water level rises were reported from South Carolina to Florida. Large waves were causing significant beach erosion along the east coast of Florida.

Tropical Storm Nicole will move through an environment that is favorable for intensification during the next few hours. Nicole will move over warm water in the Gulf Stream Current where the Sea Surface Temperatures are near 28˚C. It will move into a region where the upper level winds are weaker and there will be little vertical wind shear. Tropical Storm Nicole will extract more energy from the warmer water and it is likely to intensify to a hurricane during the next few hours.

Tropical Storm Nicole will move around the southwestern part of a surface high pressure system currently over the northeastern U.S. The high pressure system will steer Nicole toward the west-northwest during the next 12 hours. On its anticipated track Tropical Storm Nicole will make landfall on the east coast of Florida near or just to the north of West Palm Beach on Wednesday night. Nicole is likely to be a hurricane when it reaches Florida. Nicole will continue to bring strong, gusty winds and locally heavy rain to the east coast of Florida. The winds in the northern side of Nicole will continue to blow water toward the coast of Florida and the Southeast U.S. Those winds could cause a storm surge of up to 6 feet (1.8 meters) in some locations. Large waves will keep breaking on the coast and they will cause significant beach erosion.

Tropical Storm Nicole will move northwest across Central Florida on Thursday. Nicole could bring tropical storm force winds to the area around Orlando. The center of Nicole will be over northern Florida on Thursday evening. Widespread electricity outages could occur in central and northern Florida. Tropical Storm Nicole will drop locally heavy rain over central and northern Florida, and southern Georgia. Heavy rain could cause fresh water floods in some locations.

Nicole Transitions to Tropical Storm, Hurricane Warning Issued for Florida

Former Subtropical Storm Nicole completed a transition to a tropical storm on Tuesday morning and a Hurricane Warning was issued for a portion of the east coast of Florida. At 10:00 a.m. EST on Tuesday the center of Tropical Storm Nicole was located at latitude 27.8°N and longitude 72.7°W which put it about 460 miles (740 km) east of West Palm Beach, Florida. Nicole was moving toward the west at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 994 mb.

More thunderstorms formed near the center of former Subtropical Storm Nicole’s circulation. Thunderstorms near the center of circulation is one of the characteristics of a tropical storm. When the thunderstorms near the center persisted, the National Hurricane Center indicated that Nicole had complete a transition to a tropical storm. There was still a large area of tropical storm force winds around Nicole. Winds to tropical storm force extended out about 380 miles (615 km) in the northern side of Tropical Storm Nicole. Those winds were not entirely being produced by Nicole’s circulation. A large surface high pressure system was over the northeastern U.S. The high pressure system was interacting with the northern side of Nicole’s circulation to generate the large area of tropical storm force winds.

Tropical Storm Nicole will move through an environment that is favorable for intensification during the next 24 hours. Nicole will move over water where the Sea Surface Temperatures are near 28˚C. It will move into a region where the upper level winds are weaker and the vertical wind shear will diminish. Tropical Storm Nicole is likely to intensify gradually during the next 12 hours. Nicole will move over warmer water when it moves over the Gulf Stream on Wednesday. Nicole will extract more energy from the warmer water and it is likely to strengthen more rapidly on Wednesday. Tropical Storm Nicole could intensify to a hurricane when it moves over the warmer water.

The surface high pressure system currently over the northeastern U.S. will block Tropical Storm Nicole from moving toward the north. The high pressure system will steer Nicole toward the west-southwest during the next 18 hours. On its anticipated track Tropical Storm Nicole will reach the Northwestern Bahamas on Wednesday morning. Nicole will move toward the west-northwest on Wednesday when it reaches the southwestern part of the high pressure system. Nicole will reach the east coast of Florida on Wednesday night. Nicole could be a hurricane when it reaches Florida. Nicole is likely to bring strong, gusty winds and locally heavy rain to the Northwestern Bahamas and to central and northern Florida. The winds in the northern side of Nicole will blow water toward the coast of Florida and the Southeast U.S. Those winds will cause a storm surge and serious beach erosion when Nicole moves toward the coast.

Subtropical Storm Nicole began a transition to a tropical storm on Tuesday morning as it gradually strengthened. More thunderstorms formed near the center of Nicole’s circulation. Thunderstorms near the center of circulation is one of the characteristics of a tropical storm. There was still a large area of tropical storm force winds around Nicole, which is one of the characteristics of a subtropical storm. Winds to tropical storm force extended out almost 400 miles (645 km) in the northern side of Subtropical Storm Nicole. Those winds were not entirely being produced by Nicole’s circulation. A large surface high pressure system was over the northeastern U.S. The high pressure system was interacting with the northern side of Nicole’s circulation to generate the large area of tropical storm force winds.

Subtropical Storm Nicole will move through an environment that is favorable for a transition to a tropical storm during the next 24 hours. Nicole will move over water where the Sea Surface Temperatures are near 28˚C. It will move into a region where the upper level winds are weaker and the vertical wind shear will diminish. Subtropical Storm Nicole is likely to complete the transition to a tropical storm during the next 24 hours. Nicole will move over warmer water when it moves over the Gulf Stream on Wednesday. Nicole could intensify to a hurricane when it moves over the warmer water.

The surface high pressure system currently over the northeastern U.S. will block Subtropical Storm Nicole from moving toward the north. The high pressure system will steer Nicole toward the west-southwest during the next 24 hours. On its anticipated track Subtropical Storm Nicole will reach the Northwestern Bahamas on Wednesday morning. Nicole will move toward the west-northwest on Wednesday when it reaches the southwestern part of the high pressure system. Nicole will reach the coast of Southeast Florida on Wednesday night. Nicole could be a hurricane when it reaches Florida. Nicole is likely to bring strong, gusty winds and locally heavy rain to the Northwestern Bahamas and to central and northern Florida. The winds in the northern side of Nicole will blow water toward the coast of Florida and the Southeast U.S. Those winds will cause a storm surge and serious beach erosion when Nicole moves toward the coast.

Subtropical Storm Nicole Forms East of the Bahamas

Subtropical Storm Nicole formed east of the Bahamas on Monday morning. At 7:00 a.m. EST on Monday the center of Subtropical Storm Nicole was located at latitude 25.9°N and longitude 69.1°W which put it about 520 miles (835 km) east of the Northwestern Bahamas. Nicole was moving toward the north-northwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 1002 mb.

A Tropical Storm Watch was in effect for the Northwestern Bahamas.

A large low pressure system over the Atlantic Ocean east of the Bahamas exhibited more organization on Monday morning and the National Hurricane Center designated the system as Subtropical Storm Nicole. The circulation around Subtropical Storm Nicole exhibited a complex structure that is fairly common late in the hurricane season. The surface center of circulation was northeast of an upper level low east of Florida. The strongest winds near the surface were occurring far to the east of the surface center. Winds to tropical storm force extended out 275 miles (445 km) in the eastern side of Subtropical Storm Nicole. The winds in the western side of Nicole’s circulation were blowing at less than tropical storm force.

Subtropical Storm Nicole will move through an environment that is favorable for a gradual transition to a tropical storm. Nicole will move over water where the Sea Surface Temperatures are near 28˚C. The upper level low east of Florida will produce southerly winds that will blow across the top of the surface center of Subtropical Storm Nicole during the next 24 hours. Those winds will cause moderate vertical wind shear and the wind shear will inhibit intensification. Nicole will move into a region where the upper level winds are weaker on Tuesday and the wind shear will diminish. Subtropical Storm Nicole is likely to strengthen gradually during the next 24 hours. Nicole will move over warmer water when it moves over the Gulf Stream on Wednesday. Subtropical Storm Nicole is likely to make a transition to a tropical storm when it moves over the warmer water. Nicole could intensify to a hurricane when it moves over the warmer water.

The upper level low east of Florida will steer Subtropical Storm Nicole toward the northwest during the next 24 hours. A surface high pressure system currently over the Great Lakes will move over the East Coast of the U.S. and the western Atlantic Ocean. The high pressure system will block Nicole from moving toward the north. The high pressure system will steer Nicole toward the west-southwest on Tuesday and Wednesday. On its anticipated track Subtropical Storm Nicole could reach the Northwestern Bahamas on Wednesday morning. Nicole could reach the coast of Southeast Florida on Wednesday night. Nicole could be a hurricane when it reaches Florida. Nicole is likely to bring strong, gusty winds and locally heavy rain to the Northwestern Bahamas and southern Florida. The winds in the northern side of Nicole will blow water toward the coast of Florida and the Southeast U.S. Those winds will cause a storm surge and serious beach erosion when Nicole moves toward the coast.

Ian Strengthens Back to a Hurricane

One time major hurricane and former Tropical Storm Ian strengthened back to a hurricane over the Atlantic Ocean east of Florida on Thursday afternoon. At 5:00 p.m. EDT on Thursday the center of Hurricane Ian was located at latitude 29.3°N and longitude 79.9°W which put it about 240 miles (390 km) south of Charleston South Carolina. Ian was moving toward the north-northeast at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 986 mb.

A Hurricane Warning was in effect for the portion of the coast from Savannah River, Georgia to Cape Fear, North Carolina. The Hurricane Warning included Charleston, South Carolina. A Hurricane Watch was in effect for the portion of the coast from Cape Fear to Surf City, North Carolina. A Hurricane Watch was also in effect for the portion of the coast from the Flagler/Volusia County Line, Florida to Savannah River, Georgia. A Tropical Storm Warning was in effect for the portion of the coast from Cape Fear to Duck, North Carolina. The Tropical Storm Warning included Pamlico Sound. A Tropical Storm Warning is also in effect for the portion of the coast from Vero Beach, Florida to Savannah River, Georgia.

The structure of Hurricane Ian contains elements of a hurricane and elements of an extratropical cyclone. Ian has a warm core in the middle and upper troposphere, which makes it a hurricane. However, cooler, drier air wrapped around the southern side of Ian and a cold front is forming east of Ian. The developing cold front is an element of an extratropical cyclone. Many of the thunderstorms in Hurricane Ian are occurring in bands in the northern and western parts of Ian’s circulation.

The wind field around Hurricane Ian also changed when Ian started a transition to an extratropical cyclones. The circulation around Ian is interacting with a large high pressure system centered over the Great Lakes. The interaction of Ian’s circulation with the high pressure system is causing the strongest winds to be in the northwestern quadrant of Hurricane Ian. Winds to hurricane force extend out 45 miles (75 km) in the northwestern quadrant of Ian. The size of the circulation around Hurricane Ian also increased when it started the transition to an extratropical cyclone. Winds to tropical storm force extend out 400 miles (645 km) in the eastern side of Ian. Winds to tropical storm force extend out 230 miles (370 km) in the western side.

Hurricane Ian will move through an environment somewhat favorable for intensification during the next 24 hours. Ian will move over water where the Sea Surface Temperatures are near 29˚C. An upper level trough over the eastern U.S. will produce southwesterly winds that will blow toward the top of Ian’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification. Hurricane Ian could intensify, if the center moves over the warm water in the Gulf Stream current. More thunderstorms could form near the center of Ian’s circulation and could look more like a hurricane for a few hours. The vertical wind shear will eventually cause Hurricane Ian to gradually continue its transformation to an extratropical cyclone.

The upper level trough will steer Hurricane Ian toward the north-northeast during the next 24 hours. On its anticipated track the center Hurricane Ian could make landfall in South Carolina on Friday afternoon. Ian is likely to be a Category 1 hurricane on the Saffir-Simpson Scale when it reaches South Carolina. Ian will bring strong gusty winds and locally heavy rain. Widespread minor wind damage and electricity outages could occur. Air revolving around the northern side of Ian’s circulation will interact with a stationary front near the coast to enhance the rising motion in that region. The enhanced rising motion could produce very heavy rainfall near the stationary front. Heavy rain could cause flash floods in some locations. Flood Watches are in effect for parts of South Carolina and North Carolina. Southeasterly winds blowing around the northeastern side of Hurricane Ian will blow water toward the coast. A storm surge of 4 to 7 feet (1.2 to 2.0 meters) could occur. A Storm Surge Warning is in effect for the portion of the coast from the Flagler/Volusia County Line, Florida to Cape Fear, North Carolina.

Tropical Storm Ian Near Cape Canaveral

The center of Tropical Storm Ian was near Cape Canaveral, Florida on Thursday morning. At 8:00 a.m. EDT on Thursday the center of Tropical Storm Ian was located at latitude 28.5°N and longitude 80.7°W which put it about 10 miles (15 km) west of Cape Canaveral, Florida. Ian was moving toward the northeast at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 987 mb.

A Hurricane Watch was in effect for the portion of the coast from the Flagler/Volusia County Line, Florida to South Santee River, South Carolina. The Hurricane Watch included Savannah, Georgia and Charleston, South Carolina. A Tropical Storm Warning was in effect for the portion of the coast from Jupiter Inlet, Florida to Cape Lookout, North Carolina. A Tropical Storm Warning was in effect for the portion of the coast from Bonita Beach to Indian Pass, Florida. A Tropical Storm Warning was in effect for Lake Okeechobee.

Tropical Storm Ian was still producing strong winds along the east coast of Florida on Thursday morning. A National Weather Service station in Daytona Beach, Florida (KDAB) reported a sustained wind speed of 55 m.p.h. (89 km/h) and a wind gust of 76 m.p.h. (122 km/h).

Former major Hurricane Ian weakened to a tropical storm while it blew across Central Florida on Wednesday night. The structure of Ian also changed when it weakened. The areas of tropical storm force winds expanded over the Atlantic Ocean. Winds to tropical storm force extended out 400 miles (645 km) on the east side of Ian’s circulation. Winds to tropical storm force extended out 140 miles (220 km) on the western side of the circulation. Thunderstorms were occurring in bands in the northern and western parts of Tropical Storm Ian. Bands in the southern and eastern parts of Ian consisted primarily of showers and lower clouds.

Tropical Storm Ian was in the early stage of a transition to an extratropical cyclone. An upper level trough over the eastern U.S. was producing southwesterly winds that were blowing toward the top of Ian’s circulation. Those winds were causing moderate vertical wind shear. The wind shear was tilting upper part of Ian’s circulation toward the northeast. The wind shear was also starting Ian’s transition to an extratropical cyclone. Drier air was wrapping around the southern side of Tropical Storm Ian. The drier air was contributing to the lack of heavy rain in the southern and eastern parts of Ian.

Tropical Storm Ian will move through an environment somewhat favorable for intensification during the next 36 hours. Ian will move over water where the Sea Surface Temperatures are near 29˚C. The upper level trough over the eastern U.S. will continue to produce southwesterly winds that will blow toward the top of Ian’s circulation. Those winds will continue to cause moderate vertical wind shear. The wind shear will inhibit intensification. Tropical Storm Ian could intensify, if the center moves over the warm water in the Gulf Stream current. Ian could strengthen back to a hurricane during the next 36 hours.

The upper level trough will steer Tropical Storm Ian toward the north during the next 36 hours. On its anticipated track the center Tropical Storm Ian could make landfall in South Carolina on Friday afternoon. Ian could be a strong tropical storm or a Category 1 hurricane on the Saffir-Simpson Scale when it reaches South Carolina. Ian will bring strong gusty winds and locally heavy rain. Heavy rain could cause flash floods in some locations. Easterly winds blowing around the northern side of Tropical Storm Ian will blow water toward the coast. A storm surge of 4 to 6 feet (1.2 to 1.8 meters could occur.

Hurricane Ian Pounds Southwest Florida

Hurricane Ian was pounding southwest Florida on Wednesday afternoon. At 3:00 p.m. EDT on Wednesday the center of Hurricane Ian was located at latitude 26.7°N and longitude 82.2°W which put it about 20 miles (30 km) west-southwest of Punta Gorda, Florida. Ian was moving toward the north-northeast at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 175 m.p.h. (280 km/h). The minimum surface pressure was 940 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Flamingo, Florida to South Santee River, South Carolina. Tropical Storm Warnings were in effect for Bimini and Grand Bahama Island.

The National Hurricane Center stated that the center of Hurricane Ian officially made landfall on Cayo Costa, west-northwest of Ft. Myers at 3:10 p.m. EDT on Wednesday. Ian was a Category 4 hurricane on the Saffir-Simpson Scale at the time of landfall.

The Hurricane Intensity Index (HII) was 31.6. The Hurricane Size Index (HSI) was 18.1 and the Hurricane Wind Intensity Size Index (HWISI) was 49.7. Hurricane Ian was stronger and much bigger than Hurricane Charley was when Charley made landfall in Southwest Florida in 2004. Ian was similar in size and intensity to Hurricane Laura, when Laura hit Lake Charles, Louisiana in 2020. Hurricane Ian was also similar in size and intensity to Hurricane Michael when Michael hit Mexico Beach, Florida in 2018.

Hurricane Ian was producing strong gusty winds, locally heavy rain and a storm surge along the coast of Southwest Florida. A weather station maintained by the River, Estuary and Coastal Network at Redfish Pass, Florida reported a sustained wind speed of 94 m.p.h. (151 km/h) and a wind gust of 126 m.p.h. (203 km/h). A weather station at the Punta Gorda airport reported a wind gust of 124 m.p.h. (200 km/h). The Cape Coral Fire Department reported a wind gust of 110 m.p.h. (177 km/h). A station in Naples, Florida reported a storm surge of 9.05 feet (2.76 meters) and the water level was still rising. A station in Ft. Myers, Florida reported a storm surge of 5.76 feet (1.75 meters) and the water level was still rising.

An upper level trough over the eastern U.S. will steer Hurricane Ian toward the northeast during the next 24 hours. On its anticipated track Hurricane Ian will move inland over Southwest Florida. Ian will move across Central Florida on Thursday. Hurricane Ian is likely to bring a prolonged period of strong gusty winds to Southwest Florida and to Central Florida. Ian will be capable of causing severe damage. A prolonged period of strong winds could cause widespread electricity outages. Hurricane Ian will move slowly inland and 10 to 20 inches of rain could fall in some locations. Fresh water flooding could occur in Central Florida. A storm surge of up to 12 to 16 feet (3.5 to 5 meters) could occur along the coast of Southwest Florida.

The center of Hurricane Ian could be near the east coast of Florida on Thursday afternoon. Hurricane Ian could bring strong, gusty winds to the coast of the Southeastern U.S. on Thursday night and Friday. The wind will blow water toward the coast and water levels will rise along the coast.

Hurricane Ian Rapidly Intensifies to Cat. 4

Hurricane Ian rapidly intensified to Category 4 on the Saffir-Simpson Scale as it approached the coast of Southwest Florida early on Wednesday. At 8:00 a.m. EDT on Wednesday the center of Hurricane Ian was located at latitude 26.0°N and longitude 82.7°W which put it about 60 miles (95 km) southwest of Punta Gorda, Florida. Ian was moving toward the north-northeast at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 155 m.p.h. (250 km/h) and there were wind gusts to 190 m.p.h. (305 km/h). The minimum surface pressure was 937 mb.

A Hurricane Warning was in effect for the portion of the coast from Chokoloskee to Anclote River, Florida. The Hurricane Warning included Tampa Bay. Tropical Storm Warnings were in effect for all of the Florida Keys. A Tropical Storm Warning was in effect for the portion of the coast from Flamingo to Chokoloskee, Florida.

A Tropical Storm Warning was in effect for the portion of the coast from Flamingo, Florida to South Santee River, South Carolina. Tropical Storm Warnings were also in effect for the Cuban provinces of La Habana, Mayabeque and Matanzas. Tropical Storm Warnings were in effect for Bimini and Grand Bahama Island.

Hurricane Ian completed a quick eyewall replacement cycle during Tuesday night. The original eye and eyewall quickly dissipated and a new larger eye was evident on satellite and radar images. A circular eye with a diameter of 30 miles (50 km) is now present at the center of Ian’s circulation. The new eye is surrounded by a ring of strong thunderstorms and the strongest winds are occurring in that ring of storms. Bands of showers and thunderstorms are revolving around the core of Hurricane Ian’s circulation. Storms near the core are generating strong upper level divergence that is pumping mass away to the north and east of the hurricane.

The quick eyewall replacement cycle caused the circulation around Ian to get bigger. Winds to hurricane force extended out 40 miles (65 km) from the center of Ian’s circulation. Winds to tropical storm force extended out 175 miles (280 km) from the center of circulation. The Hurricane Intensity Index (HII) was 33.3. The Hurricane Size Index (HSI) was 16.5 and the Hurricane Wind Intensity Size Index (HWISI) was 49.6. Hurricane Ian was capable of causing regional severe damage.

Hurricane Ian is now stronger than Hurricane Charley was when Charley made landfall in Southwest Florida in 2004, and Ian is much bigger than Charley was. Hurricane Ian is very similar in size and intensity to Hurricane Michael, when Michael hit Northwest Florida in 2018.

Ian will move through an environment favorable for a powerful hurricane during the next few hours. Ian will move over water where the Sea Surface Temperatures are near 29˚C. An upper level trough over the eastern U.S. will produce southwesterly winds that will blow toward the top of Ian’s circulation. Those winds will cause vertical wind shear. The wind shear is not likely to be strong enough during the next few hours to cause Hurricane Ian to weaken significantly before it makes landfall in Southwest Florida.

The upper level trough over the eastern U.S. will steer Hurricane Ian toward the north-northeast on Wednesday. On its anticipated track the center of Hurricane Ian could make landfall on the coast of Southwest Florida between Ft. Myers and Sarasota on Wednesday afternoon. Ian could move slowly inland over Central Florida on Thursday. Hurricane Ian is likely to bring a prolonged period of strong gusty winds to Southwest Florida and to Central Florida. Ian will be capable of causing severe damage. A prolonged period of strong winds could cause widespread electricity outages. Hurricane Ian will move slowly inland and 10 to 20 inches of rain could fall in some locations. Fresh water flooding could occur in Central Florida. A storm surge of 12 to 16 feet (3.5 to 5 meters) could occur along the coast of Southwest Florida.

Hurricane Ian is bigger and stronger than Hurricane Charley was when Charley hit Southwest Florida in 2004. Ian is likely to cause much more wind damage than Charley caused. Hurricane Ian is also likely to cause a higher storm surge along the coast than Charley caused.

Hurricane Ian Moves Closer to Southwest Florida

Hurricane Ian moved closer to Southwest Florida on Tuesday night. At 11:00 p.m. EDT on Tuesday the center of Hurricane Ian was located at latitude 24.9°N and longitude 82.9°W which put it about 110 miles (175 km) southwest of Naples, Florida. Ian was moving toward the north-northeast at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (225 km/h). The minimum surface pressure was 952 mb.

A Hurricane Warning was in effect for the portion of the coast from Chokoloskee to Anclote River, Florida. The Hurricane Warning included Tampa Bay. Tropical Storm Warnings were in effect for all of the Florida Keys. A Tropical Storm Warning was in effect for the portion of the coast from Flamingo to Chokoloskee, Florida. A Tropical Storm Warning was in effect for Lake Okeechobee. A Tropcial Storm Warning was in effect for the portion of the coast from Anclote River to Indian Pass, Florida. A Tropical Storm Warning was in effect for the portion of the coast from Flamingo, Florida to South Santee River, South Carolina. Tropical Storm Warnings were also in effect for the Cuban provinces of La Habana, Mayabeque and Matanzas. Tropical Storm Warnings were in effect for Bimini and Grand Bahama Island.

Hurricane Ian appeared to go through a quick eyewall replacement cycle on Tuesday evening. The original eye and eyewall quickly dissipated and a new larger eye was evident on satellite and radar images. The new eye had a diameter of 35 miles (55 km). The new eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Hurricane Ian’s circulation. Storms near the core generated upper level divergence that pumped mass away to the north and east of the hurricane.

The quick eyewall replacement cycle temporarily interrupted the intensification of Hurricane Ian, but it also caused the circulation around Ian to get bigger. Winds to hurricane force extended out 45 miles (75 km) from the center of Ian’s circulation. Winds to tropical storm force extended out 140 miles (225 km) from the center of circulation. The Hurricane Intensity Index (HII) was 22.1. The Hurricane Size Index (HSI) was 14.1 and the Hurricane Wind Intensity Size Index (HWISI) was 36.2. Hurricane Ian was capable of causing regional major damage.

Ian will move through an environment favorable for intensification during the next 12 hours. Ian will move over water where the Sea Surface Temperatures are near 29˚C. An upper level trough over the eastern U.S. will produce southwesterly winds that will blow toward the top of Ian’s circulation. Those winds will cause vertical wind shear. The wind shear is not likely to be strong enough during the next 12 hours to prevent intensification of Hurricane Ian. Ian could strengthen to Category 4 on the Saffir-Simpson Scale on Wednesday morning. The upper level winds are likely to get stronger on Wednesday afternoon which would cause the wind shear to increase. Hurricane Ian is likely to start to weaken slowly when the vertical wind shear increases.

The upper level trough over the eastern U.S. will steer Hurricane Ian toward the north-northeast on Wednesday. On its anticipated track the center of Hurricane Ian could make landfall on the coast of Southwest Florida between Ft. Myers and Sarasota on Wednesday afternoon. Ian could move slowly inland over Central Florida on Thursday. Hurricane Ian is likely to bring a prolonged period of strong gusty winds to Southwest Florida and to Central Florida. Ian will be capable of causing major damage. A prolonged period of strong winds could cause widespread electricity outages. Hurricane Ian will move slowly inland and 10 to 20 inches of rain could fall in some locations. Extensive fresh water flooding could occur in Central Florida. A storm surge of 8 to 12 feet (2.4 to 3.5 meters) could occur along the coast of Southwest Florida.

The center of Hurricane Ian could make landfall near the location where Hurricane Charley made landfall in 2004. Ian will not be as strong as Charley was in 2004, but Ian will be a lot bigger than Charley. Hurricane Ian could be stronger than Hurricane Irma was in 2017 when Irma hit Southwest Florida, but Ian will not be as big as Irma was.

Major Hurricane Ian Hits Western Cuba

Hurricane Ian rapidly intensified to a major hurricane before it hit western Cuba on Tuesday morning. At 8:00 a.m. EDT on Tuesday the center of Hurricane Ian was located at latitude 22.6°N and longitude 83.6°W which put it about 10 miles (15 km) north-northeast of Pinar del Rio, Cuba. Ian was moving toward the north-northwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 150 m.p.h. (240 km/h). The minimum surface pressure was 950 mb.

A Hurricane Warning was in effect for the portion of the coast from Bonita Beach to Anclote River, Florida. The Hurricane Warning included Tampa Bay. Hurricane Warnings were in effect for the Cuban provinces of Isla Juventud, Pinar del Rio and Artemisa. A Hurricane Watch was in effect for the portion of the coast from Anclote River to Suwannee River, Florida. Tropical Storm Warnings were in effect for the Lower Florida Keys from Channel 5e Bridge to Key West including the Dry Tortugas. A Tropical Storm Warning was in effect for the portion of the coast from Flamingo to Bonita Beach, Florida. A Tropical Storm Warning was in effect for Lake Okeechobee. A Tropcial Storm Warning was in effect for the portion of the coast from Anclote River to Suwannee River, Florida. A Tropical Storm Warning was in effect for the portion of the coast from Jupiter Inlet to the Volusia/Brevard County Line, Florida. Tropical Storm Warnings were also in effect for the Cuban provinces of La Habana, Mayabeque and Matanzas. A Tropical Storm Watch was in effect for the portion of the coast from Suwannee River to Indian Pass, Florida. A Tropical Storm Watch was in effect for the portion of the coast from Deerfield Beach to Jupiter Inlet, Florida. A Tropical Storm Watch was in effect for the portion of the coast from the Volusia/Brevard County Line, Florida to Altamaha Sound, Georgia.

Hurricane Ian rapidly intensified to a major hurricane before making landfall in western Cuba on Tuesday morning. A circular eye with a diameter of 30 miles (50 km) was at the center of Ian’s circulation. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Hurricane Ian. Storms near the core generated upper level divergence that pumped mass away form the hurricane in all directions. The removal of large quantities of mass was allowing the surface pressure to decrease rapidly.

Winds to hurricane force extended out 35 miles (55 km) from the center of Hurricane Ian’s circulation. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation. The Hurricane Intensity Index (HII) was 23.6 The Hurricane Size Index (HSI) was 11.5 and the Hurricane Wind Intensity Size Index (HWISI) was 35.1. Hurricane Ian was very similar in size and intensity to Hurricane Harvey from 2017 and Hurricane Delta from 2020. Hurricane Ian was capable of causing regional major damage.

Hurricane Ian is not likely to spend enough time over western Cuba for Ian to weaken significantly. After the core of Hurricane Ian moves north of Cuba, Ian will move through an environment very favorable for intensification during the next 18 hours. Ian will move over water where the Sea Surface Temperatures are near 30˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Ian is likely to intensify to Category 4 on the Saffir-Simpson Scale by Wednesday. An upper level trough over the eastern U.S. will produce southwesterly winds that will blow toward the top of Ian’s circulation on Wednesday. Those winds will cause the vertical wind shear to increase. Hurricane Ian is likely to start to weaken slowly when the vertical wind shear increases.

Hurricane Ian will move around the western end of a high pressure system over the western Atlantic Ocean. The high pressure system will steer Ian toward the north during the next 18 hours. The upper level trough will steer Hurricane Ian more toward the north-northeast on Wednesday. On its anticipated track Hurricane Ian will move away from western Cuba. Weather conditions should gradually improve over western Cuba as Ian moves farther away. Hurricane Ian will be south-southwest of Tampa, Florida on Wednesday morning. The winds steering Ian could weaken later on Wednesday. Hurricane Ian could make landfall just south of Tampa, Florida on Wednesday evening. Ian could move very slowly inland over Central Florida on Thursday.

Hurricane Ian is likely to bring a prolonged period of strong gusty winds to the area around Tampa and St. Petersburg and to Central Florida. Ian will be capable of causing major damage. A prolonged period of strong winds could cause widespread electricity outages. Hurricane Ian will move slowly inland and 10 to 20 inches of rain could fall in some locations. Extensive fresh water flooding could occur in Central Florida. A storm surge of 5 to 10 feet (1.5 to 3 meters) could occur in parts of Tampa Bay. Storm surges will also occur along the coast of Southwest Florida.
