Hurricane Milton was weakening gradually on Wednesday afternoon, but Milton was still a major hurricane.  An upper level trough over the southern Mississippi River Valley was producing southwesterly winds that were blowing toward the top of Milton’s circulation.  Those winds were causing moderate vertical wind shear.  The upper level winds were also inhibiting the upper level divergence to the west of Hurricane Milton.  The wind shear was causing Hurricane Milton to weaken gradually.

A circular eye was present at the center of Hurricane Milton.  The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Thunderstorms were occurring in bands in the eastern and northern parts of Hurricane Milton.  Bands in the southern and western parts of Milton’s circulation consisted primarily of showers and lower clouds.  Storms near the center of Milton generated upper level divergence that pumped mass away to the northeast of the hurricane.

Even though Hurricane Milton is weakening, the circulation around Milton is getting larger.  Winds to hurricane force extend out 35 miles (55 km) from the center of Milton’s circulation.  Winds to tropical storm force extend out 250 miles (400 km) from the center of Hurricane Milton.

The Hurricane Intensity Index (HII) for Hurricane Milton is 22.1.  The Hurricane Size Index (HSI) is 16.8 and the Hurricane Wind Intensity Size Index (HWISI) is 38.9.  Hurricane Milton is similar in intensity to Hurricane Irma when Irma hit southwest Florida in 2017.  Milton is not as big as Irma was.

Hurricane Milton will move through an environment unfavorable for intensification during the next few hours.  Milton will move over water where the Sea Surface Temperatures are near 29°C.  However, the upper level trough over the southern Mississippi River Valley will continue to cause moderate to strong vertical wind shear.  The wind shear will cause Hurricane Milton to continue to weaken gradually during the next few hours.

The upper level trough over the southern Mississippi River Valley will steer Hurricane Milton toward the northeast east during the next 12 hours.  On its anticipated track, the center of Hurricane Milton will make landfall in a few hours on the west coast of Florida near or just to the south of Tampa.

Even though Hurricane Milton weakened today, Milton is still expected to be a major hurricane when it hits the west coast of Florida.   Milton will bring strong gusty winds and heavy rain to the west coast of Florida.   Milton will also bring strong winds and heavy rain to central Florida.

Hurricane Warnings are in effect for many of the counties in Central Florida.  Those Hurricane Warnings include Orlando.

Milton will be capable of causing major damage.  Heavy rains will cause floods in some locations. Widespread electricity outages are likely.

Flood Watches are in effect for much of the Florida Peninsula.

Milton will also produce a storm surge of up to 15 feet (4.5 meters) along the west coast of Florida.  The highest storm surge is likely to occur along the portion of the coast just to the south of Tampa.  A storm surge of 8 to 12 feet (2,4 to 3.7 meters) could occur in Tampa Bay.

A Storm Surge Warning is in effect for the portion of the coast from Flamingo to the Yankeetown, Florida.  The Storm Surge Warning includes Tampa Bay and Charlotte Harbor.  A Storm Surge Warning is also in effect for the portion of the coast from Sebastian Inlet, Florida to Altamaha Sound, Georgia.

Thunderstorms in bands in the eastern periphery of Hurricane Milton have already produced tornadoes over South Florida.  A Tornado Watch is in effect for much of the Florida Peninsula.

Elsewhere over the Atlantic Ocean, Hurricane Leslie intensified east-northeast of the Northern Leeward Islands.  At 5:00 p.m. EDT on Wednesday the center of Hurricane Leslie was located at latitude 22.2°N and longitude 49.0°W which put the center about 955 miles (1535 km) east-northeast of the Northern Leeward Islands.  Leslie was moving toward the northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 982 mb.

Hurricane Milton Moves Toward West Coast of Florida

Hurricane Milton was moving toward the west coast of Florida on Wednesday morning.  At 11:00 a.m. EDT on Wednesday the center of Hurricane Milton was located at latitude 25.8°N and longitude 84.3°W which put the center about 190 miles (305 km) southwest of Tampa, Florida.  Milton was moving toward the northeast at 17 m.p.h. (28 km/h).  The maximum sustained wind speed was 145 m.p.h. (235 km/h) and there were wind gusts to 170 m.p.h. (275 km/h).  The minimum surface pressure was 931 mb.

A Tropical Storm Watch is in effect for the portion of the coast from Savannah River, Georgia to the South Santee River, South Carolina.

Hurricane Milton started to weaken gradually on Wednesday morning, but Milton was still a powerful, dangerous hurricane.  An upper level trough over the southern Mississippi River Valley was producing southwesterly winds that were blowing toward the top of Milton’s circulation.  Those winds were causing moderate vertical wind shear.  The upper level winds were also inhibiting the upper level divergence to the west of Hurricane Milton.  The wind shear was causing Hurricane Milton to weaken gradually.

Even though Hurricane Milton was weakening gradually, it was still a major hurricane.  A small circular eye was present at the center of Milton’s circulation.  The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Thunderstorms were occurring in bands in the eastern and northern parts of Hurricane Milton.  Bands in the southern and western parts of Milton’s circulation consisted primarily of showers and lower clouds.  Storms near the center of Milton generated upper level divergence that pumped mass away to the northeast of the hurricane.

Although Hurricane Milton is weakening, the circulation around Milton is getting larger.  Winds to hurricane force extend out 35 miles (55 km) from the center of Milton’s circulation.  Winds to tropical storm force extend out 175 miles (280 km) from the center of Hurricane Milton.

The Hurricane Intensity Index (HII) for Hurricane Milton is 29.9. The Hurricane Size Index (HSI) is 14.4 and the Hurricane Wind Intensity Size Index (HWISI) is 44.3.  Hurricane Milton is similar in intensity to Hurricane Charley when Charley hit southwest Florida in 2004.  Milton is much larger than Charley was.

Hurricane Milton will move through an environment unfavorable for intensification during the next 12 hours.  Milton will move over water where the Sea Surface Temperatures are near 29°C.  However, the upper level trough over the southern Mississippi River Valley will continue to cause moderate to strong vertical wind shear.  The wind shear will cause Hurricane Milton to weaken gradually during the next 12 hours.

The upper level trough over the southern Mississippi River Valley will steer Hurricane Milton toward the northeast east during the next 12 hours.  On its anticipated track, the center of Hurricane Milton will make landfall on Wednesday night on the west coast of Florida near or just to the south of Tampa.

Even though Hurricane Milton will weaken today, Milton is still expected to be a major hurricane when it hits the west coast of Florida.  Milton will bring strong gusty winds and heavy rain to the west coast of Florida.  Milton will also bring strong winds and heavy rain to central Florida.

Hurricane Warnings are in effect for many of the counties in Central Florida.  Those Hurricane Warnings include Orlando.

Milton will also produce a storm surge of up to 15 feet (4.5 meters) along the west coast of Florida.  The highest storm surge is likely to occur along the portion of the coast just to the south of Tampa>  A storm surge of 8 to 12 feet (2,4 to 3.7 meters) could occur in Tampa Bay.

A Storm Surge Warning is in effect for the portion of the coast from Flamingo to the Yankeetown, Florida.  The Storm Surge Warning includes Tampa Bay and Charlotte Harbor.  A Storm Surge Warning is also in effect for the portion of the coast from Sebastian Inlet, Florida to Altamaha Sound, Georgia.

A Storm Surge Watch has been issued for the portion of the coast from Altamaha Sound, Georgia to Edisto Beach, South Carolina.

Thunderstorms in bands in the eastern periphery of Hurricane Milton were already producing tornadoes over South Florida.  A Tornado Watch is in effect for the southern half of the Florida Peninsula.

Elsewhere over the Atlantic Ocean, Hurricane Leslie intensified east-northeast of the Northern Leeward Islands.  At 11:00 a.m. EDT on Wednesday the center of Hurricane Leslie was located at latitude 21.7°N and longitude 48.4°W which put the center about 985 miles (1585 km) east-northeast of the Northern Leeward Islands.  Leslie was moving toward the northwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 985 mb.

Low Pressure System To Drop Heavy Rain on Central, South Florida

A low pressure system designated as Invest 90L will drop heavy rain over parts of Central and South Florida during the next 24 hours. At 2:00 p.m. EDT on Tuesday the center of Invest 90L was located at latitude 26.9°N and longitude 93.9°W which put it about 75 miles (120 km) west-southwest of Sarasota, Florida. The low pressure system was moving toward the east-northeast at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 25 m.p.h. (40 km/h) and there were wind gusts to 35 m.p.h. (55 km/h). The minimum surface pressure was 1009 mb.

A low pressure system developed over the eastern Gulf of Mexico on Tuesday. The low pressure system was designated as Invest 90L. It was approaching the west coast of Florida near Sarasota on Tuesday afternoon. The low pressure system was being steered toward the east-northeast. It will move across the Florida Peninsula during Tuesday night. The low pressure system will drop heavy rain over parts of Central and South Florida.

A Flood Watch was in effect for South Florida.

A well defined low level circulation was visible on satellite images. Thunderstorms were occurring in the eastern and northern parts of the low pressure system. Thunderstorms were also occurring in a band just east of the center of circulation. Bands north and west of the center of the low pressure system consisted primarily of showers and lower clouds.

The low pressure system will move through an environment unfavorable for the formation of a tropical cyclone during the next 24 hours. The low pressure system will move over water where the Sea Surface Temperatures are near 30°C during the next few hours. Then it will move over the Florida Peninsula. An upper level trough over the eastern U.S. will produce westerly winds that will blow across the top of the low pressure system. Those winds will cause strong vertical wind shear. The combination of movement over land and strong vertical wind shear is likely to prevent the development of a tropical cyclone during the next 24 hours.

The low pressure system could move into a more favorable environment when it moves over the western Atlantic Ocean on Friday. The upper level trough could move northeast of the low pressure system which would cause the vertical wind shear to decrease. The U.S. National Hurricane Center is indicating that probability is 20% that the low pressure system develops into a tropical cyclone after it moves over the western Atlantic Ocean northeast of Florida.

The upper level trough will steer the low pressure system toward the east-northeast during the next 24 hours. On its anticipated track the low pressure system will reach the west coast of Florida near Sarasota in a few hours. The center of the low pressure system is likely to pass south of Orlando and Daytona Beach. It will drop heavy rain over parts of Central and South Florida. Some thunderstorms could approach severe criteria.

At 4:00 a.m. EST on Wednesday the center of Tropical Storm Nicole was located at latitude 27.8°N and longitude 80.7°W which put it about 60 miles (95 km) southeast of Orlando, Florida. Nicole was moving toward the west-northwest at 14 m.p.h. (22 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. (145 km/h). The minimum surface pressure was 981 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Boca Raton, Florida to South Santee River, South Carolina. The Tropical Storm Warning included West Palm Beach, Ft. Pierce, Daytona Beach, Jacksonville, and Charleston, South Carolina. A Tropical Storm Warning was in effect for Lake Okeechobee. 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.

According to the National Hurricane Center, the center of Hurricane Nicole made landfall on the east coast of Florida just to the south of Vero Beach. The maximum sustained wind speed was 75 m.p.h. (120 km) at the time of landfall. Winds to hurricane force extended out 25 miles (40 km) in the eastern side of Nicole’s circulation at the time of landfall. Winds to tropical storm force extended out 450 miles (725 km) from the center of circulation.

Hurricane Nicole weakened to a tropical storm after the center moved inland over Central Florida, but Nicole was bringing strong, gusty winds to Central Florida. A weather station in Vero Beach reported a sustained wind speed of 40 m.p.h. (65 km/h) and a wind gust of 60 m.p.h. (97 km/h). A weather station in Melbourne reported a sustained wind speed of 52 m.p.h. (84 km/h) and a wind gust of 64 m.p.h. (103 km/h). A weather station in Orlando reported a sustained wind speed of 43 m.p.h. (69 km/h) and a wind gust of 63 m.p.h. (102 km/h). Tropical Storm Nicole was dropping heavy rain over parts of the Florida Peninsula.

Tropical Storm Nicole will move around the southwestern part of a surface high pressure system near the East Coast of the U.S. The high pressure system will steer Nicole toward the northwest during the next 12 hours. On its anticipated track the center of Tropical Storm Nicole will move over northern Florida on Thursday evening. An upper level trough and a cold front will approach Nicole from the west on Thursday night. The upper level trough and cold front will steer Tropical Storm Nicole toward the northeast on Friday. The center of Nicole could be over South Carolina on Friday afternoon.

Tropical Storm Nicole will weaken gradually as it moves across Central Florida. Nicole will continue to bring strong, gusty winds to central and northern Florida. Gusty winds could cause widespread power outages. Even though the center of Nicole will be inland, easterly winds will continue to blow water toward the east coast of Florida. Tropical Storm Nicole could cause a storm surge of up to 5 feet (1.5 meters) in some locations. Large waves will continue to cause significant beach erosion. Nicole will drop heavy rain over parts of central and northern Florida and southern Georgia. Heavy rain could cause fresh water floods in some locations.

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.

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.

Subtropical Storm Nicole Strengthens

Subtropical Storm Nicole strengthened on Tuesday morning as it moved over the Western Atlantic Ocean east of the Bahamas. At 7:00 a.m. EST on Tuesday the center of Subtropical Storm Nicole was located at latitude 27.7°N and longitude 72.0°W which put it about 385 miles (615 km) east of the Northwestern Bahamas. Nicole was moving toward the west-northwest at 8 m.p.h. (13 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 992 mb.

A Hurricane Warning was in effect for the Abacos, Berry Islands, Bimini and Grand Bahama Island. A Hurricane Watch was in effect for the portion of the coast from the Volusia/Brevard County Line to Hallandale Beach, Florida. The Hurricane Watch included Melbourne, West Palm Beach and Ft. Lauderdale. A Hurricane Watch was in effect for Lake Okeechobee. Tropical Storm Warnings were in effect for Andros Island, New Providence and Eleuthera. A Tropical Storm Warning was in effect for the portion of the coast from Altamaha Sound, Georgia to Hallandale Beach, Florida. The Tropical Storm Warning includes Jacksonville and Daytona Beach. A Tropical Storm Watch was in effect for the portion of the coast from Hallandale Beach to Ocean Reef, Florida. The Tropical Storm Watch included Miami. A Tropical Storm Watch was in effect for the portion of the coast from Bonita Beach to the Ochlockonee River, Florida.

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.

Large Tropical Storm Cristobal Churns Toward Louisiana

Large Tropical Storm Cristobal churned toward the coast of Louisiana on Saturday night.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Cristobal was located at latitude 26.2°N and longitude 90.2°W which put it about 200 miles (320 km) south of Grand Isle, Louisiana.  Cristobal was moving toward the north at 12 m.p.h. (19 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 993 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Intracoastal City, Louisiana to the Okaloosa/Walton County Line in Florida including Lake Pontchartrain and Lake Maurepas.

The circulation around Tropical Storm Cristobal continued to be very large.  Winds to tropical storm force extended out 250 miles (400 km) to the east of the center of Cristobal.  A thunderstorm in a rainband on the eastern periphery of the circulation around Tropical Storm Cristobal produced a tornado near Orlando, Florida.  Winds to tropical storm force extended out 160 miles (260 km) in the western half of the circulation.  The winds were blowing at less than tropical storm force near the center of circulation.  The center passed just to the west of NOAA buoy 42001 on Saturday evening.  The buoy measured a surface pressure of 29.34 inches (993.8 mb).  More thunderstorms appeared to be forming north and south of the center of circulation on Saturday night.

Tropical Storm Cristobal will move through an environment favorable for intensification during the next 12 to 18 hours.  Cristobal will move over water where the Sea Surface Temperature is near 27°C.  It will move under the western side of an upper level ridge.  The ridge will produce southerly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear but the the shear will not be great enough to prevent intensification.  Tropical Storm Cristobal will strengthen on Sunday.  If thunderstorms consolidate around the center of circulation, then there is a chance that Cristobal could strengthen into a hurricane.

Tropical Storm Cristobal will move around the western end of a subtropical high pressure system on Sunday.  The high will steer Cristobal toward the north.  A ridge in the middle troposphere will move north of Tropical Storm Cristobal later on Sunday.  The ridge will turn Cristobal toward the north-northwest.  On its anticipated track Tropical Storm Cristobal will approach the coast of Louisiana on Sunday afternoon.  The center of Cristobal could make landfall between Grand Isle and Morgan City.

Tropical Storm Cristobal will bring gusty winds to Northwest Florida, Southwest Alabama, Southern Mississippi and Southeastern Louisiana.  Those winds will push water toward the coast.  A storm surge of 1 to 4 feet (0.3 to 1.3 meters) will be possible.  The water level could rise 3 to 6 feet (1 to 2 meters) in parts of southeastern Louisiana.  Areas outside of levee protection systems could go under water.  Tropical Storm Cristobal will drop heavy rain over parts of southern Mississippi and Southeastern Louisiana.  Flash Flood Watches have been issued for those regions.
