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.

Hurricane Ian Rapidly Intensifies to Cat. 2

Hurricane Ian rapidly intensified to Category 2 on the Saffir-Simpson Scale south of Cuba on Monday afternoon. At 5:00 p.m. EDT on Monday the center of Hurricane Ian was located at latitude 20.3°N and longitude 83.2°W which put it about 155 miles (250 km) southeast of the western tip of Cuba. Ian was moving toward the north-northwest at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h). The minimum surface pressure was 972 mb.

A Hurricane Warning was in effect for the portion of the coast from Englewood 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. Hurricane Watches were in effect for the portion of the coast from Anclote River to Suwannee River, Florida and from Englewood to Bonita Beach, Florida. Tropical Storm Warnings were in effect for the Lower Florida Keys from Seven Mile Bridge to Key West including the Dry Tortugas. A Tropical Storm Warning was in effect for the portion of the coast from Flamingo to Englewood, 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 Florida Keys from Seven Mile Bridge to Channel 5 Bridge. 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 Jupiter Inlet, Florida to Altamaha Sound, Georgia. A Tropical Storm Watch was in effect for Lake Okeechobee.

Hurricane Ian rapidly intensified to Category 2 over the northwestern Caribbean Sea south of Cuba on Monday afternoon. A circular eye with a diameter of 13 miles (20 km) formed at the center of Ian’s circulation. The eye was surrounded by a nearly complete ring of 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.

The circulation around Hurricane Ian got bigger on Monday afternoon as Ian got stronger. Winds to hurricane force extended out 35 miles (55 km) from the center of 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 16.5 The Hurricane Size Index (HSI) was 9.6 and the Hurricane Wind Intensity Size Index (HWISI) was 26.1. Hurricane Ian was capable of causing regional serious damage.

Hurricane Ian will move through an environment very favorable for intensification during the next 24 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 rapidly during the next 24 hours. Ian is likely to intensify to a major hurricane during the next 18 hours. Hurricane Ian could intensify to Category 4 on the Saffir-Simpson Scale by Wednesday.

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-northwest during the next 12 hours. Ian will move toward the north when it reaches the western end of the high pressure system. On its anticipated track the center of Hurricane Ian will be near western Cuba on Tuesday morning. Hurricane Ian could be a major hurricane when it approaches western Cuba. Ian will be southwest of Tampa, Florida on Wednesday afternoon.

Hurricane Ian will bring strong winds and locally heavy rain to western Cuba. Ian will be capable of causing regional major damage in western Cuba. Widespread outages of electricity are likely. Heavy rain could cause flash floods in some locations.

The steering currents could weaken on Wednesday. If the steering currents weaken, the center of Hurricane Ian could stall just west or northwest of the area around Tampa and St. Petersburg. The strongest winds will be in the eastern side of Ian’s circulation. The area around Tampa and St. Petersburg could experience a prolonged period of strong winds. When the center of Ian is west of Tampa, the winds will blow from the south in the area around Tampa. Southerly winds will push water into Tampa Bay and a storm surge of 5 to 10 feet (1.5 to 3.0 meters) is possible. If Hurricane Ian stalls, some locations in west central Florida could receive 10 to 20 inches (250 to 500 mm) of rain. Heavy rain is likely to cause fresh water flooding.

Disturbance Drops Rain on Southeast U.S.

A disturbance designated as Invest 90L dropped rain over the southeast U.S. on Monday morning. At 8:00 a.m. EDT on Monday the center of the disturbance was located near latitude 32.7°N and longitude 86.7°W which put it about 30 miles (50 km) north-northwest of Montgomery, Alabama. The disturbance was moving toward the north-northeast at 23 m.p.h. (37 km/h). The maximum sustained wind speed was 30 m.p.h. (50 km/h) and and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1011 mb.

A disturbance that formed over the Gulf of Mexico during the weekend moved quickly toward the north-northeast and it was located over the southeast U.S. on Monday morning. The center of the disturbance made landfall on the northern Gulf Coast on Sunday night near Pensacola, Florida. The disturbance was dropping locally heavy rain over parts of Alabama and western Georgia on Monday morning. The disturbance will move quickly toward the north-northeast and it will merge with a cold front over the southeastern U.S. Locally heavy rain will spread over eastern Tennessee, western South Carolina, western North Carolina, eastern Kentucky, western Virginia and West Virginia. Heavy rain could cause flash floods in some locations.

Tropical Storm Mindy Forms near Florida Panhandle

Tropical Storm Mindy formed near the Florida Panhandle on Wednesday afternoon. At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Mindy was located at latitude 29.0°N and longitude 86.3°W which put it about 90 miles (145 km) west-southwest of Apalachicola, Florida. Mindy was moving toward the northeast at 21 m.p.h. (33 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1008 mb.

A Tropical Storm Warning was issued for the portion of the coast from Mexico Beach to the Steinhatchee River, Florida.

A surface low pressure system spun up quickly near the Florida Panhandle on Wednesday afternoon and the National Hurricane Center designated the system as Tropical Storm Mindy. More thunderstorms were forming near the center of Mindy. Storms near the center started to generate upper level divergence that pumped mass away to the northeast of the tropical storm. The removal of mass caused the surface pressure to decrease. NOAA buoy 42039 reported a sustained wind speed of 38 m.p.h. (61 km/h) and a wind gust of 51 m.p.h. (83 km/h) at 4:40 p.m. EDT. The buoy also reported a surface pressure of 1007.8 mb.

Tropical Storm Mindy could strengthen a little during the next few hours before it makes landfall on the coast of Northwest Florida. Mindy will move over water where the Sea Surface Temperature is near 30˚C. It will move under the eastern side of an upper level low over the western Gulf of Mexico. The upper low will produce southwesterly winds that will blow toward the top of Mindy’s circulation. Those winds will cause moderate vertical wind shear and the shear will limit potential intensification.

The upper level low will steer Tropical Storm Mindy quickly toward the northeast during the next 12 hours. On its anticipated track Tropical Storm Mindy will make landfall on the coast near Port St. Joe, Florida on Wednesday evening. Mindy will move more toward the east-northeast on Thursday when it reaches the westerly winds in the middle latitudes. Tropical Storm Mindy will produce gusty winds along the coast of Northwest Florida. Mindy could drop locally heavy rain over parts of northern Florida and southern Georgia. Flash Flood Watches are in effect for parts of northern Florida. Southerly winds on the eastern side of Tropical Storm Mindy will push waves toward the coast and some beach erosion is likely.

Elsewhere, Hurricane Larry moved closer to Bermuda on Wednesday afternoon. At 5:00 p.m. EDT on Wednesday the center of Hurricane Larry was located at latitude 28.9°N and longitude 59.2°W which put it about 405 miles (655 km) southeast of Bermuda. Larry was moving toward the northwest at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 110 m.p.h. (175 km/h) and there were wind gusts to 130 m.p.h. (210 km/h). The minimum surface pressure was 966 mb. A Tropical Storm Warning was in effect for Bermuda.

Tropical Depression Ida Brings Rain and Storms to Southeast U.S.

Tropical Depression Ida brought rain and thunderstorms to the southeast U.S. on Monday. At 5:00 p.m. EDT on Monday the center of Tropical Depression Ida was located at latitude 32.6°N and longitude 90.3°W which put it about 20 miles (30 km) north-northwest of Jackson, Mississippi. Ida was moving toward the north-northeast at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 999 mb.

Former Hurricane Ida weakened to a tropical depression over Mississippi on Monday afternoon. Even though the speed of the wind circulating around Ida decreased, Tropical Depression Ida was still dropping locally heavy rain and generating a few tornadoes over the southeast U.S. Thunderstorms in bands on the eastern side of Ida were dropping locally heavy rain over parts of Mississippi, Alabama, northwest Florida and northwestern Georgia. Flash Flood Watches were in effect for all of those places. Tornadoes were reported in southeastern Mississippi, and southwestern and central Alabama.

Electricity was still out in all of New Orleans. Southerly winds blowing around the eastern side of Tropical Depression Ida’s circulation were still pushing water toward the coast. Those winds were blowing to near tropical storm force in some locations. A weather station at Fort Morgan, Alabama was reporting a sustained wind speed of 38 m.p.h. (61 km/h) and a wind gust of 47 m.p.h. (76 km/h). The water levels had decreased along the coast, but the persistent southerly winds were preventing the water levels from returning to normal. The water levels should continue to decrease when Tropical Depression Ida moves farther away from the coast.

Tropical Depression Ida will move northeast during the next 72 hours. The center of Ida will cross Tennessee on Tuesday. Ida could be over West Virginia on Wednesday and it could reach the east coast of the U.S. on Thursday. Tropical Depression Ida will continue to drop locally heavy rain over the eastern U.S. The circulation around Ida will interact with a cold front moving slowly south toward the Ohio River. The interaction between Ida and the cold front could enhance rainfall over the Tennessee and Ohio River Valleys. Flash Flood Watches are in effect across the region from Tennessee to New Jersey.

Elsewhere over the Atlantic Ocean, Tropical Storm Julian made a transition to an extratropical cyclone west of the Azores on Monday morning and Tropical Storm Kate developed east-northeast of the Leeward Islands. At 5:00 p.m. EDT on Monday the center of Tropical Storm Ida was located at latitude 22.7°N and longitude 50.9°W which put it about 805 miles (1295 km) east-northeast of the Leeward Islands. Kate was moving toward the north at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1006 mb.

Tropical Storm Grace Brings Wind and Rain to Jamaica

Tropical Storm Grace brought wind and rain to Jamaica on Tuesday. At 2:00 p.m. EDT on Tuesday the center of Tropical Storm Grace was located at latitude 18.5°N and longitude 77.5°W which put it about 25 miles (40 km) east of Montego Bay, Jamaica. Grace was moving toward the west at 15 m.p.h. (24 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 1005 mb.

A Hurricane Watch was in effect for the portion of the coast from Cabo Catoche to Punta Allen, Mexico. Tropical Storm Warnings were in effect for Jamaica, the Cayman Islands and the Cuban provinces of Santiago de Cuba, Granma, Las Tunas and Camaguey. Tropical Storm Watches were in effect for the Cuban provinces of Ciego de Avila, Sancti Spiritus, Cinefuegos, Matanzas, Pinar del Rio and Isla de la Juventud.

The center of Tropical Storm Grace was moving along the northern coast of Jamaica on Tuesday afternoon. Grace was causing gusty winds over Jamaica and it was also dropping heavy rain. Tropical Storm Grace strengthened earlier on Tuesday as it approached Jamaica. More thunderstorms developed near the center of circulation. Bands of showers and thunderstorms were revolving around the center of Grace. Storms near the center generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 70 miles (110 km) on the eastern side of Grace. The winds in the western half of the circulation were blowing mostly at less than tropical storm force.

Tropical Storm Grace will move south of a subtropical high pressure system over the Atlantic Ocean. The high will steer Grace toward the west during the next several days. On its anticipated track Tropical Storm Grace will move across Jamaica during the next few hours. Grace could reach the Cayman Islands early on Wednesday. Grace could approach the Yucatan Peninsula on Wednesday night.

Tropical Storm Grace is not likely to strengthen during the next few hours while the center of circulation is near the northern coast of Jamaica. Grace will move through an environment favorable for intensification after it moves west of Jamaica. Grace will move over water where the Sea Surface Temperatures are near 30°C. It will move under the southern side of an upper level ridge centered near Florida. The ridge will produce easterly winds that will blow toward the top of Grace’s circulation. Those winds will cause some vertical wind shear, but the shear will be too small to prevent intensification. Tropical Storm Grace could strengthen to a hurricane over the northwestern Caribbean Sea. A period of rapid intensification could occur if an inner core with an eye and an eyewall forms at the center of Grace.

Elsewhere, Tropical Depression Fred was dropping heavy rain over parts of the southeastern U.S. and Tropical Storm Henri was strengthening south of Bermuda.

At 11:00 a.m. EDT on Tuesday the center of Tropical Depression Fred was located at latitude 33.4°N and longitude 84.7°W which put it about 30 miles (50 km) south-southwest of Atlanta, Georgia. Fred was moving toward the north-northeast at 17 m.p.h. (28 km/h). The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1007 mb.

At 2:00 p.m. EDT on Tuesday the center of Tropical Storm Henri was located at latitude 30.4°N and longitude 64.3°W which put it about 143 miles (215 km) south-southeast of Bermuda. Henri was moving toward the west-southwest at 6 m.p.h. (10 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 1000 mb. A Tropical Storm Watch was in effect for Bermuda.

Tropical Storm Fred Makes Landfall in Northwest Florida

Tropical Storm Fred made landfall on the coast of Northwest Florida near Cape San Blas on Monday afternoon. At 5:00 p.m. EDT on Monday the center of Tropical Storm Fred was located at latitude 29.9°N and longitude 85.3°W which put it about 25 miles (40 km) northwest of Apalachicola Florida. Fred was moving toward the north-northeast at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 995 mb.

A Tropical Storm Warning was in effect for the portion of the coast from the Okaloosa/Walton County Line to the Stienhatchee River, Florida.

The National Hurricane Center stated that Tropical Storm Fred made landfall on the coast of Northwest Florida near Cape San Blas, which is about 25 miles (40 km) west of Apalachicola. The maximum sustained wind speed at the time of landfall was 65 m.p.h. (105 km/h) and the minimum surface pressure was 994 mb. Fred was dropping heavy rain over parts of northwest Florida and southeast Alabama. There were reports of flash floods in some locations. Tropical Storm Fred was also causing a storm surge along the coast of the Gulf of Mexico where the wind was pushing the water toward the shore. A Storm Surge Warning was in effect for the portion of the coast from Indian Pass to Yankeetown, Florida.

Tropical Storm Fred will move around the western end of a subtropical high pressure over the Atlantic Ocean. The high will steer Fred toward the north-northeast during the next 36 hours. On its anticipated track Tropical Storm Fred will be over northern Georgia on Tuesday afternoon. Fred could be over West Virginia by Wednesday. Tropical Storm Fred will weaken steadily as it moves farther inland. However, Fred will move through a very moist environment and it will drop heavy rain over parts of the southeastern U.S. Rain will spread over western Georgia on Monday evening. Flash Flood Watches have been issued for parts of northwest Florida, southeast Alabama, western and northern Georgia, southeastern Tennessee and western North Carolina. Tropical Storm Fred could also cause sporadic power outages as it moves inland.

Elsewhere, Tropical Depression Grace was dropping heavy rain on parts of the Dominican Republic and Haiti, and former Tropical Depression Eight strengthened to Tropical Storm Henri southeast of Bermuda.

At 5:00 p.m. EDT on Monday the center of Tropical Depression Grace was located at latitude 17.9°N and longitude 72.4°W which put it about 50 miles (80 km) southeast of Port Au Prince, Haiti. Grace was moving toward the west-northwest at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).

Henri was moving toward the south-southwest at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1010 mb. A Tropical Storm Watch was in effect for Bermuda.

Tropical Storm Fred Strengthens on Approach to Northwest Florida

Tropical Storm Fred strengthened as it approach the coast of Northwest Florida on Monday morning. At 8:30 a.m. EDT on Monday the center of Tropical Storm Fred was located at latitude 28.7°N and longitude 85.6°W which put it about 80 miles (130 km) south-southwest of Apalachicola Florida. Fred was moving toward the north at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 993 mb.

A Tropical Storm Warning was in effect for the portion of the coast from the Wakulla/Jefferson County Line to Navarre, Florida.

A reconnaissance plane sampling Tropical Storm Fred on Monday morning found that Fred was intensifying. Satellite and radar images showed that Tropical Storm Fred was developing a structure that is typical of tropical storms. Radar images also showed that the inner end of a rainband was wrapping around the center of Fred and a small eye might be forming at the center of circulation. Bands of showers and thunderstorms were revolving around the core of Tropical Storm Fred. Storms near the core generated upper level divergence that pumped mass away from the tropical storm. The distribution of thunderstorms and the wind field around Fred continued to be asymmetrical. The strong thunderstorms were around the center of circulation and in bands on the eastern side of Tropical Storm Fred. Bands in the western half of the tropical storm consisted primarily of showers and lower clouds. The strongest winds were also in the eastern half of Fred. Winds to tropical storm force extended out 90 miles (145 km) on the eastern side of the circulation. Winds in the much of western half of Fred were blowing at less than tropical storm force.

Tropical Storm Fred will move through an environment favorable for intensification during the next few hours. Fred will move over water where the Sea Surface Temperatures are near 30°C. It will move under the western side of an upper level ridge centered near Cuba. The ridge will produce southwesterly winds that will blow toward the top of Fred’s circulation. Those winds will cause some vertical wind shear. The wind shear will inhibit intensification, but the shear will not be strong enough to prevent Fred from intensifying. Tropical Storm Fred is likely to continue to intensify gradually during the next few hours.

Tropical Storm Fred will move around the western end of a subtropical high pressure system over the western Atlantic Ocean. The high pressure system will steer Fred toward the north during the next 24 hours. On its anticipated track Tropical Storm Fred will make landfall on the coast of Northwest Florida between Apalachicola and Panama City in a few hours. Fred will bring gusty winds and locally heavy rain to Northwest Florida, southeast Alabama and southern Georgia. Flash Flood Watches have been issued for some of those areas. Tropical Storm Fred could also cause a storm surge of up to seven feet (two meters) along portions of the coast. The part of the coast around the northeastern Gulf of Mexico is very vulnerable to storm surges. A Storm Surge Warning is in effect for the portion of the coast from Indian Pass to Yankeetown, Florida. Thunderstorms in bands on the eastern side of Tropical Storm Fred could produce tornadoes.

Elsewhere, Tropical Depression Grace was passing south of Hispaniola and Tropical Depression Eight was slowly getting better organized east of Bermuda.

At 8:00 a.m. EDT on Monday the center of Tropical Depression Grace was located at latitude 17.4°N and longitude 70.9°W which put it about 125 miles (200 km) southeast of Port Au Prince, Haiti. Grace was moving toward the west at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1008 mb. Tropical Storm Watches were in effect for the entire coast of the Dominican Republic and the entire coast of Haiti. A Tropical Storm Watch was issued for Jamaica.

At 8:00 a.m. EDT on Monday the center of Tropical Depression Eight was located at latitude 31.7°N and longitude 62.8°W which put it about 120 miles (195 km) east-southeast of Bermuda. The tropical depression was moving toward the south at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 35 m.p.h. (505km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1012 mb. A Tropical Storm Watch was in effect for Bermuda.

Tropical Storm Fred Gets a Little Stronger

Tropical Storm Fred got a little stronger on Sunday night. At 11:00 p.m. EDT on Sunday the center of Tropical Storm Fred was located at latitude 27.3°N and longitude 85.9°W which put it about 200 miles (320 km) south of Panama City, Florida. Fred was moving toward the north-northwest 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 999 mb.

A Tropical Storm Warning was in effect for the portion of the coast from the Wakulla/Jefferson County Line to Navarre, Florida.

Tropical Storm Fred strengthened gradually on Sunday night. Upper level divergence pumped mass away from the tropical storm and the minimum surface pressure decreased to 999 mb. The decrease in pressure generated more force and the wind speed increased to 50 m.p.h. (80 km/h). The distribution of thunderstorms and the wind field around Tropical Storm Fred remained asymmetrical. The strongest thunderstorms were occurring in bands on the eastern side of Fred. The strongest winds were also occurring on the eastern side of Tropical Storm Fred. Winds to tropical storm force extended out 90 miles (145 km) on the eastern side of Fred. The winds in the western half of the circulation were blowing at less than tropical storm force.

Tropical Storm Fred will move through an environment somewhat favorable for intensification during the next 18 hours. Fred will move over water where the Sea Surface Temperatures are near 30°C. It will move under the western side of an upper level ridge centered near Cuba. The ridge will produce southwesterly winds that will blow toward the top of Fred’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification, but the shear will not be strong enough to prevent Fred from intensifying. Tropical Storm Fred is likely to continue to intensify gradually during the next 18 hours.

Tropical Storm Fred will move around the western end of a subtropical high pressure system over the western Atlantic Ocean. The high pressure system will steer Fred toward the north during the next 24 hours. On its anticipated track Tropical Storm Fred will approach the coast of Northwest Florida on Monday afternoon. Fred will bring gusty winds and locally heavy rain to Northwest Florida. Tropical Storm Fred could also cause a storm surge of up to six feet (1.8 meters) along portions of the coast. The part of the coast around the northeastern Gulf of Mexico is very vulnerable to storm surges. A Storm Surge Warning is in effect for the portion of the coast from Indian Pass to Yankeetown, Florida.

Elsewhere, former Tropical Storm Grace weakened to a tropical depression as it passed south of Puerto Rico and Tropical Depression Eight formed east-northeast of Bermuda. At 11:00 p.m. EDT on Sunday the center of Tropical Depression Grace was located at latitude 17.3°N and longitude 68.6°W which put it about 120 miles (195 km) southeast of Santo Domingo, Dominican Republic. Grace was moving toward the west at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1011 mb. Tropical Storm Watches were in effect for the entire coast of the Dominican Republic and the entire coast of Haiti.

At 11:00 p.m. EDT on Sunday the center of Tropical Depression Eight was located at latitude 33.2°N and longitude 62.7°W which put it about 135 miles (220 km) east-northeast of Bermuda. The tropical depression was moving toward the south at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1014 mb. A Tropical Storm Watch was in effect for Bermuda.

Possible Development near Southeast U.S.

A low pressure system could develop near the coast of the Southeast U.S. during the next 48 hours. At 8:00 a.m. EDT on Friday the center of a developing low pressure system currently designated as Invest 90L was located at latitude 31.3°N and longitude 79.3°W which put it about 150 miles (240 km) east of Brunswick, Georgia. It was moving toward the east-southeast at 9 m.p.h. (15 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 1017 mb.

Early morning visible satellite images appeared to show that a low pressure system was forming along a nearly stationary front off the coast of the southeast U.S. More thunderstorms were forming in the developing low pressure system and some rotation was evident in satellite loops. Thunderstorms appeared to be organizing into bands. The southern end of an upper level trough over the eastern U.S. was producing westerly that were blowing across the top of the developing low pressure system. Those winds were causing moderated vertical wind shear. The upper level winds were also inhibiting the development of thunderstorms on the western side of the developing low pressure system.

The low pressure system will move through an environment somewhat favorable for the formation of a tropical cyclone during the next 48 hours. It will move over water where the Sea Surface Temperatures are near 28°C. The upper level trough will move northeast of the low pressure system on Saturday and the upper level winds will weaken. An upper level low east of the Bahamas could enhance upper level divergence to the southeast of the developing low pressure system. The National Hurricane Center is indicating the probability is 30% that a tropical cyclone forms during the next 48 hours. A reconnaissance plane has been tentatively tasked to investigate the system on Saturday afternoon, if necessary.
