The center of Hurricane Grace made landfall on the east coast of the Yucatan Peninsula southeast of Tulum on Thursday morning. The maximum sustained wind speed was 80 m.p.h. (130 km/h) at the time of landfall. Winds to hurricane force extended out 35 miles (55 km) from the center of Hurricane Grace. Winds to tropical storm force extended out 140 miles (220 km) from the center of circulation. Grace will produce strong gusty winds over the Yucatan. It will also drop heavy rain and flash floods are likely to occur. Hurricane Grace will weaken gradually back to a tropical storm while it moves across the Yucatan.

Hurricane Grace will move over the southwestern Gulf of Mexico on Thursday night. Grace will move into an environment favorable for intensification when it moves over the Gulf of Mexico. Grace will move over water where the Sea Surface Temperatures are near 30°C. It will move into a region where the upper level winds are weak and there will be little vertical wind shear. Grace is likely to intensify back to a hurricane on Friday.

Hurricane Grace will move south of a subtropical high pressure system that extends over the Gulf of Mexico. The high will steer Grace toward the west during the next several days. On its anticipated track Hurricane Grace will move across the Yucatan Peninsula on Thursday. Grace will move over the southwestern Gulf of Mexico on Thursday night. Hurricane Grace could approach the coast of Mexico between Veracruz and Tampico on Friday night.

Elsewhere, former Tropical Storm Fred was dropping heavy rain over parts of the northeastern U.S. and Tropical Storm Henri was moving west toward the east coast of the U.S.

At 5:00 a.m. EDT on Thursday the center of former Tropical Storm Fred was located at latitude 42.0°N and longitude 76.0°W which put it about 15 miles (25 km) south of Binghamton, New York. Fred was moving toward the east-northeast at 17 m.p.h. (28 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).

Henri was moving toward the west at 9 m.p.h. (15 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 995 mb.

Tropical Storm Grace Brings Wind and Rain to Cayman Islands

Tropical Storm Grace brought wind and rain to the Cayman Islands on Wednesday morning. At 8:00 a.m. EDT on Wednuesday the center of Tropical Storm Grace was located at latitude 19.1°N and longitude 81.4°W which put it about 20 miles (30 km) southwest of Grand Cayman. Grace was moving toward the west-northwest at 16 m.p.h. (26 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 993 mb.

A Hurricane Warning was in effect for the portion of the coast from Cancun to Punta Herrero, Mexico. The Hurricane Warning included Cozumel. A Hurricane Watch was in effect for the Cayman Islands. A Tropical Storm Warning was in effect for the Cayman Islands. Tropical Storm Warnings were in effect for the portions of the coast from Cancun to Campeche, Mexico and from Punta Herrero to Puerto Costa Maya, Mexico. Tropical Storm Watches were in effect for the Cuban provinces of Isla de la Juventud and Pinar del Rio.

Tropical Storm Grace was getting better organized on Wednesday morning. A reconnaissance plane was reporting that an eye with a diameter of 18 miles (29 km) was forming at the center of Grace. The developing eye was surround 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 center of Tropical Storm Grace. Storms near the center of circulation were generating upper level divergence that was pumping mass away from the tropical storm. The removal of mass was causing the surface pressure to decrease. Winds to tropical storm force extended out 115 miles (185 km) from the center of Grace.

Tropical Storm Grace will move through an environment favorable for intensification during the next 18 hours. 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 is likely to strengthen to a hurricane over the northwestern Caribbean Sea. A period of rapid intensification could occur once an inner core with an eye and an eyewall forms at the center of Grace.

Tropical Storm Grace will move south of a subtropical high pressure system over the Atlantic Ocean. The high will steer Grace toward the west-northwest during the next several days. On its anticipated track Tropical Storm Grace will approach the Yucatan Peninsula on Wednesday night. Grace will be a hurricane when it approaches the Yucatan. It will bring strong winds and locally heavy rain. Flash flooding is likely to occur in some locations. Grace will also cause a storm surge along the east coast of the Yucatan Peninsula.

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.

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.

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.

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 1014 mb. A Tropical Storm Watch was in effect for Bermuda.

Fred Strengthens Back to a Tropical Storm

Former Tropical Storm Fred strengthened back to a tropical storm over the eastern Gulf of Mexico on Sunday morning. At 11:00 a.m. EDT on Sunday the center of Tropical Storm Fred was located at latitude 26.1°N and longitude 84.9°W which put it about 335 miles (540 km) south-southeast of Pensacola, Florida. Fred was moving toward the north-northwest at 12 m.p.h. (19 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 in effect for the portion of the coast from the Wakulla/Jefferson County Line to Navarre, Florida. A Tropical Storm Watch was in effect from the portion of the coast from Navarre, Florida to the Alabama/Florida border.

Data from a reconnaissance plane on Sunday morning indicated that a low level center of circulation had redeveloped in Tropical Storm Fred. The circulation around Fred was asymmetrical. The strongest thunderstorms were occurring in bands on the eastern side of Tropical Storm Fred and the strongest winds were occurring in those bands. Bands in the western half of Fred consisted primarily of showers and lower clouds. Storms on the eastern side of Tropical Storm Fred generated upper level divergence that pumped mass away to the north of the tropical storm. Winds to tropical storm force extended out 80 miles (130 km) in the northeastern quadrant of Fred. The winds in the other parts 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 24 hours. Fred will move over water where the Sea Surface Temperatures are near 30°C. It will move between an upper level low over the northern coast of the Gulf of Mexico and an upper level ridge centered over Cuba. The upper low and 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 intensify gradually during the next 24 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-northwest during the next 24 hours. On its anticipated track Tropical Storm Fred will approach the coast of Northwest Florida on Monday. 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.

Elsewhere, Tropical Storm Grace was passing south of Puerto Rico. At 11:00 a.m. EDT on Sunday the center of Tropical Storm Grace was located at latitude 17.2°N and longitude 66.0°W which put it about 85 miles (135 km) south of San Juan, Puerto Rico. Grace was moving toward the west-northwest at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 40 m.p.h. (56 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1010 mb.

Tropical Storm Warnings were in effect for Puerto Rico including Culebra and Vieques, and the U.S. Virgin Islands. A Tropical Storm Warning was also in effect for the portion of the coast from Samana, Dominican Republic to the southern border with Haiti. Tropical Storm Watches were in effect for the entire coast of Haiti and from Samana, Dominican Republic to the northern border with Haiti.

Tropical Storm Grace Brings Wind and Rain to Lesser Antilles

Tropical Storm Grace brought wind and rain to the Lesser Antilles on Saturday evening. At 11:00 p.m. EDT on Saturday the center of Tropical Storm Grace was located at latitude 16.8°N and longitude 62.4°W which put it about 170 miles (280 km) east-southeast of St. Croix. Grace was moving toward the west at 20 m.p.h. (32 km/h). The maximum sustained wind speed was 40 m.p.h. (56 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1010 mb.

Tropical Storm Warnings were in effect for Puerto Rico including Culebra and Vieques and the U.S. Virgin Islands. Tropical Storm Warnings were also in effect for Saba and St. Eustatius, St. Martin, St.Bathelemy and St. Maarten. A Tropical Storm Warning was also in effect for the portion of the coast from Cabo Caucedo to Samana, Dominican Republic. Tropical Storm Watches were in effect for the portions of the coast from Cabo Caucedo, Dominican Republic to the southern border with Haiti and from Samana, Dominican Republic to the northern border with Haiti. A Tropical Storm Watch was also in effect for the entire coast of Haiti.

The circulation around Tropical Storm Grace was not very well organized on Saturday evening. There was a broad low level center of circulation. The strongest thunderstorms were occurring in bands in the western half of Grace. Bands on the eastern side of the circulation consisted primarily of showers and lower clouds. Strong easterly winds in the lower levels of the atmosphere were pushing the lower part of Tropical Storm Grace to the west of the middle and upper parts of the circulation. Those winds were causing moderate vertical wind shear and the shear was contributing to the asymmetrical distribution of thunderstorms. Winds to tropical storm force extended out 35 miles (55 km) on the northern side of Grace. Winds in the southern half of the circulation were blowing at less than tropical storm force.

Tropical Storm Grace will move through an environment somewhat favorable for intensification during the next 24 hours. Grace will move over water where the Sea Surface Temperatures are near 28°C. The winds in the lower levels could weaken a little and there could be a little less vertical wind shear. If the wind shear decreases, it could allow Tropical Storm Grace to become better organized.

Tropical Storm Grace will move south of the subtropical high pressure system over the Atlantic Ocean. The high will steer Grace toward the west-northwest during the next 24 hours. On its anticipated track Tropical Storm Grace could approach Puerto Rico by Sunday afternoon. Grace could approach the Dominican Republic on Sunday night.

Elsewhere, the remnants of former Tropical Depression Fred were slowly reorganizing northwest of Cuba. At 11:00 p.m. EDT on Saturday the center of former Tropical Depression Fred was located at latitude 23.8°N and longitude 84.3°W which put it about 125 miles (200 km) west-northwest of Havana, Cuba. The remnants of Fred were moving toward the west-northwest 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 1012 mb.

The remnants of former Tropical Depression Fred are forecast to reorganize on Sunday and to strengthen back to a tropical storm. Fred is forecast to move toward the northern Gulf Coast. Watches and warnings could be issued for a portion of the coast on Sunday.

Potential Tropical Cyclone Seven Prompts Watches for Leeward Islands

A threat from Potential Tropical Cyclone Seven prompted the issuance of Tropical Storm Watches for some of the Leeward Islands on Friday morning. At 11:00 a.m. EDT on Friday the center of Potential Tropical Cyclone Seven was located at latitude 15.3°N and longitude 49.3°W which put it about 840 miles (1350 km) east of the Leeward Islands. The potential tropical cyclone was moving toward the west at 21 m.p.h. (33 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 1010 mb.

Tropical Storm Watches were issued for Antigua, Barbuda, St. Kitts and Nevis, Montserrat, Saba and St. Eustatius.

The National Hurricane Center designated a tropical disturbance east of the Leeward Islands as Potential Tropical Cyclone Seven on Friday morning in order to be able to issue watches for the system. The circulation around Potential Tropical Cyclone Seven was still in the early stages of organizing on Friday morning. There was not a well defined low level center of circulation. The strongest thunderstorms were occurring in bands on the western side of the tropical disturbance. There were few thunderstorms in the eastern side of the disturbance.

Potential Tropical Cyclone Seven will move through an environment favorable for the formation of a tropical cyclone during the next several days. It will move over water where the Sea Surface Temperatures are near 28°C. The disturbance will move through a region where the winds will blow from the east at all levels in the troposphere. The winds near the surface could be stronger near the surface, which could cause some vertical wind shear in the lower levels. The shear might not be too strong and a tropical cyclone is likely to form during the next 48 hours.

Potential Tropical Cyclone Seven will move south of the subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer the tropical disturbance toward the west during the next 36 hours. On its anticipated track Potential Tropical Cyclone Seven will approach the northern Leeward Islands on Saturday night. It could be near Puerto Rico by Sunday night.

Elsewhere, Tropical Depression Fred was moving across central Cuba. At 11:00 a.m. EDT on Friday the center of Tropical Depression Fred was located at latitude 22.3°N and longitude 78.4°W which put it about 20 miles (30 km) northeast of Moron, Cuba. Fred was moving toward the west-northwest at 12 m.p.h. (19 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 1013 mb.

A Tropical Storm Warning was in effect for the Florida Keys from Ocean Reef to the Dry Tortugas including Florida Bay. A Tropical Storm Watch was in effect for the portion of the coast from Englewood to Ocean Reef, Florida including Florida Bay. Tropical Storm Watches were also in effect for the Cuban provinces of Sancti Spiritis, Villa Clara, Ciego de Avila and Camaguey.

The center of Tropical Depression Fred was moving west-northwest across central Cuba on Friday morning. An upper level low centered over the northeastern Gulf of Mexico was causing westerly winds that were blowing across the top of Fred’s circulation. Those winds were causing moderate vertical wind shear. The wind shear and the increased friction over land were preventing Tropical Depression Fred from strengthening. The upper level low is forecast to weaken during the weekend and Fred could intensify to a tropical storm once the center moves past Cuba. Tropical Depression Fred will move around the western end of the subtropical high pressure system over the Atlantic Ocean and it could move over the Gulf of Mexico on Saturday.

Tropical Depression Fred Prompts Watches for Florida Keys and Southwest Florida

The forecast for Tropical Depression Fred prompted the National Hurricane Center to issue Tropical Storm Watches for the Florida Keys and the coast of Southwest Florida. At 5:00 p.m. EDT on Thursday the center of Tropical Depression Fred was located at latitude 21.3°N and longitude 75.3°W which put it about 70 miles (110 km) east of Holguin, Cuba. Fred was moving toward the west-northwest at 12 m.p.h. (19 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 1012 mb.

A Tropical Storm Watch was issued for the Florida Keys from Ocean Reef to the Dry Tortugas. A Tropical Storm Watch was also issued for the portion of the coast from Bonita Beach to Ocean Reef, Florida including Florida Bay. Tropical Storm Watches remained in effect for the Cuban provinces of Ciego de Avila, Camaguey, Holguin, Las Tunas and Granma.

Tropical Depression Fred was spinning just to the north of eastern Cuba on Thursday afternoon. The circulation around Fred was significantly weaker after its passage over mountains in the Dominican Republic and Haiti. A distinct low level rotation was evident on visible satellite images, but there were not a lot of thunderstorms near the center of circulation. New thunderstorms appeared to be developing in bands on the southeastern side of Tropical Depression Fred. Bands in the other parts of Fred consisted primarily of showers and lower clouds.

Tropical Depression Fred will move through an environment somewhat favorable for intensification during the next 36 hours. Fred will move over water where the Sea Surface Temperatures are near 30°C. It will move under the southeastern part of an upper low over Florida. The upper low will produce westerly winds that will blow toward the top of Fred’s circulation. Those winds will cause moderate vertical wind shear and the shear will inhibit intensification. The southern part of the circulation around Tropical Depression Fred will pass over Cuba. The friction will be greater where the air flows over land and that will also inhibit intensification. Tropical Depression Fred could slowly strengthen if the center stays over the warm water north of Cuba, but intensification is likely to be gradual.

Tropical Depression Fred will move around the western end of a subtropical high pressure system over the Atlantic Ocean. The high will steer Fred toward the west-northwest during the next 24 hours. Fred will move more toward the northwest during the weekend, when it gets closer to the western end of the high pressure system. On its anticipated track the center of Tropical Depression Fred will move near the northern coast of Cuba during the next 24 hours. Fred could approach the Florida Keys by Saturday morning. It will bring gusty winds and locally heavy rain to the Keys. Fred is likely to move over the Gulf of Mexico during the weekend.
