Tropical Storm Ida Prompts Hurricane Watch for Louisiana and Mississippi

The threat posed by Tropical Storm Ida prompted the issuance of a Hurricane Watch for the coast of Louisiana and Mississippi on Thursday night. At 11:00 p.m. EDT on Thursday the center of Tropical Storm Ida was located at latitude 18.6°N and longitude 80.5°W which put it about 65 miles (105 km) southeast of Grand Cayman. Ida was moving toward the 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. (65 km/h). The minimum surface pressure was 1006 mb.

A Hurricane Watch was issued for the portion of the coast from Cameron, Louisiana to the Mississippi/Alabama border. The Hurricane Watch included New Orleans, Lake Ponchartrain and Lake Maurepas. Tropical Storm Warnings were in effect for the Cayman Islands. Tropical Storm Warnings were also in effect for the Cuban provinces of Matanzas, Mayabeque, Havana, Artemisa, Pinar del Rio and the Isle of Youth. A Tropical Storm Watch was in effect for the portion of the coast from the Mississippi/Alabama border to the Alabama/Florida border.

The circulation around Tropical Storm Ida was gradually becoming more organized. A few more thunderstorms were beginning to develop near the center of Ida. A rainband was wrapping around the eastern and northern sides of the center of circulation. However, the distribution of thunderstorms was still asymmetrical. The strongest thunderstorms were occurring in bands forming on the eastern side of Tropical Storm Ida. An upper level low near Florida was producing south-southwesterly winds that were blowing over the western side of Ida’s circulation. Those winds were causing moderate vertical wind shear and they were contributing to the asymmetrical distribution of thunderstorms. Wind to tropical storm force extended out 70 miles (110 km) in the northeastern quadrant of Tropical Storm Ida. The winds in the other parts of Ida’s circulation were blowing at less than tropical storm force.

Tropical Storm Ida will move around the southwestern part of a subtropical high pressure system over the Atlantic Ocean during the next several days. The high will steer Ida toward the northwest. On its anticipated track Tropical Storm Ida will move over the Cayman Islands during the next few hours. Ida could be near western Cuba on Friday evening. Tropical Storm Ida will bring gusty winds and locally heavy rain to the Cayman Islands and parts of western Cuba. Ida will move over the Gulf of Mexico during the weekend. It could approach the central coast of the Gulf of Mexico on Sunday.

Tropical Storm Ida will move into an environment that will become more favorable for intensification during the next 60 hours. The upper low near Florida will move off to the northwest and it will weaken. When the upper low weakens, they vertical wind shear will decrease. Ida will move over water where the Sea Surface Temperatures are near 30°C. Ida is likely to strengthen to a hurricane during the next 36 hours. An upper level ridge will be over the Gulf of Mexico during the weekend. The upper level winds will be weak and there will be little vertical wind shear. Ida could intensify rapidly once an inner core with an eye and an eyewall develop. Ida could rapidly intensify to a major hurricane over the Gulf of Mexico.

On its anticipated track Ida could approach the coast of Louisiana on Sunday. Ida could be a major hurricane when it nears the coast. Ida will bring strong winds and locally heavy rain to the central Gulf Coast. It could generate a significant storm surge of up to 7 to 11 feet (2 to 3.3 meters). A Storm Surge Watch has been issued for the coast from Sabine Pass to the Alabama/Florida border. The Storm Surge Watch includes Vermilion Bay, Lake Borgne, Lake Pontchartrain, Lake Maurepas, and Mobile Bay.

Tropical Depression Nine Strengthens to Tropical Storm Ida

Former Tropical Depression Nine strengthened to Tropical Storm Ida late on Thursday afternoon. At 5:20 p.m. EDT on Thursday the center of Tropical Storm Ida was located at latitude 18.0°N and longitude 79.8°W which put it about 130 miles (205 km) southeast of Grand Cayman. Ida was moving toward the northwest at 14 m.p.h. (22 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. (65 km/h). The minimum surface pressure was 1006 mb.

Tropical Storm Warnings were in effect for the Cayman Islands. Tropical Storm Warnings were also in effect for the Cuban provinces of Matanzas, Mayabeque, Havana, Artemisa, Pinar del Rio and the Isle of Youth.

A reconnaissance flight into former Tropical Depression Nine by an Air Force Reserve Hurricane Hunter plane on Thursday afternoon found sustained winds to tropical storm force and the National Hurricane Center upgraded the system to Tropical Storm Ida. The circulation around Tropical Storm Ida was gradually becoming more organized. A rainband was wrapping around the eastern and northern sides of the center of Ida. However, the distribution of thunderstorms was still asymmetrical. The strongest thunderstorms were occurring in bands forming on the eastern side of Tropical Storm Ida. An upper level low near Florida was producing south-southwesterly winds that were blowing over the western side of Ida’s circulation. Those winds were causing moderate vertical wind shear and they were contributing to the asymmetrical distribution of thunderstorms.

Tropical Storm Ida will move around the southwestern part of a subtropical high pressure system over the Atlantic Ocean during the next several days. The high will steer Ida toward the northwest. On its anticipated track Tropical Storm Ida will move over the Cayman Islands on Thursday night. Ida could be near western Cuba on Friday evening. Tropical Storm Ida will bring gusty winds and locally heavy rain to the Cayman Islands and parts of western Cuba. Ida will move over the Gulf of Mexico during the weekend. It could approach the central coast of the Gulf of Mexico on Sunday.

Tropical Storm Ida will move into an environment that will become more favorable for intensification during the next 72 hours. The upper low near Florida will move off to the northwest and it will weaken. When the upper low weakens, they vertical wind shear will decrease. Ida will move over water where the Sea Surface Temperatures are near 30°C. Ida could strengthen to a hurricane during the next 36 hours. An upper level ridge will be over the Gulf of Mexico during the weekend. The upper level winds will be weak and there will be little vertical wind shear. Ida could intensify rapidly once an inner core with an eye and an eyewall develop. Ida could rapidly intensify to a major hurricane over the Gulf of Mexico.

On its anticipated track Ida could approach the coast of Louisiana on Sunday. Ida could be a major hurricane when it nears the coast. Ida will bring strong winds and locally heavy rain to the central Gulf Coast. It could generate a significant storm surge.

Tropical Depression Nine Forms over Northwest Caribbean

Tropical Depression Nine formed over the northwestern Caribbean Sea on Thursday morning. At 11:00 a.m. EDT on Thursday the center of Tropical Depression Nine was located at latitude 16.9°N and longitude 79.2°W which put it about 210 miles (340 km) southeast of Grand Cayman. The tropical depression was moving toward the 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). The minimum surface pressure was 1005 mb.

Tropical Storm Warnings were issued for the Cayman Islands. Tropical Storm Warnings were also issued for the Cuban provinces of Matanzas, Mayabeque, Havana, Artemise, Pinar del Rio and the Isle of Youth.

Satellite images indicated the development of a circulation within a tropical wave over the northwestern Caribbean Sea on Thursday morning and the National Hurricane Center designated the system as Tropical Depression Nine. The circulation around Tropical Depression Nine was still organizing. Bands of showers and thunderstorms were starting to form. The strongest thunderstorms were occurring in bands forming on the eastern side of the tropical depression. An upper level low near Florida was producing south-southwesterly winds that were blowing across the western side of Tropical Depression Nine. Those winds were causing moderate vertical wind shear and they were contributing to the asymmetrical distribution of thunderstorms.

Tropical Depression Nine will move around the southwestern part of a subtropical high pressure system during the next several days. The high will steer the depression toward the northwest. On its anticipated track Tropical Depression Nine will move over the Cayman Islands on Thursday night. It could be near western Cuba on Friday evening. The system will move over the Gulf of Mexico during the weekend. It could approach the center coast of the Gulf of Mexico on Sunday.

Tropical Depression Nine will move into an environment that will become more favorable for intensification during the next three days. The upper low near Florida will move off to the northwest and it will weaken. When the upper low weakens, they vertical wind shear will decrease. The tropical depression will move over water where the Sea Surface Temperatures are near 30°C. Tropical Depression Nine could strengthen to a tropical storm later today. It could strengthen to a hurricane during the next 36 hours. An upper level ridge will be over the Gulf of Mexico during the weekend. The upper level winds will be weak and there will be little vertical wind shear. A period of rapid intensification could occur when the system moves toward the central Gulf Coast. It could rapidly intensify to a major hurricane.

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.

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).

At 5:00 p.m. EDT on Monday the center of Tropical Storm Henri was located at latitude 31.0°N and longitude 62.9°W which put it about 145 miles (2305 km) southeast of Bermuda. 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 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.

Tropical Storm Fred Makes Landfall in Dominican Republic

Tropical Storm Fred made landfall on the coast of the Dominican Republic on Wednesday afternoon. At 2:00 p.m. EDT on Wednesday the center of Tropical Storm Fred was located at latitude 18.5°N and longitude 70.1°W which put it about 30 miles (50 km) west of Santo Domingo, Dominican Republic. Fred was moving toward the west-northwest at 16 m.p.h. (26 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 1006 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Punta Palenque, Dominican Republic to the northern border with Haiti. A Tropical Storm Watch was in effect for the portion of the coast from Gonaives, Haiti to the northern border with the Dominican Republic. Tropical Storm Watches were in effect for the Southeastern Bahamas and the Turks and Caicos. Tropical Storm Watches were also in effect for the Cuban provinces of Ciego de Avila, Camaguey, Las Tunas, Holguin, Granma, Santiago de Cuba and Guantanamo.

The center of Tropical Storm Fred made landfall on the south coast of the Dominican Republic west of Santo Domingo on Wednesday afternoon. Fred became better organized and a little stronger prior to making landfall. A band of thunderstorms wrapped around the eastern and northern sides of the center of Tropical Storm Fred. Storms near the center generated upper level divergence that pumped mass away from the tropical storm and the surface pressure decreased slightly. The strongest winds were occurring in the eastern half of Tropical Storm Fred. At the time of landfall winds to tropical storm force extended out 60 miles (95 km) from the center of Fred’s circulation.

Tropical Storm Fred will move around the southern side of a subtropical high pressure system over the Atlantic Ocean. The high will steer Fred toward the west-northwest during the next several days. On its anticipate track Tropical Storm Fred will move across the western part of the Dominican Republic and northern Haiti during the next 24 hours. Fred will drop locally heavy rain and flash floods could occur in some locations.

Mountains in the Dominican Republic and Haiti will significantly disrupt the low level circulation of Tropical Storm Fred. Fred is likely to weaken to a tropical depression during the next 12 hours. The circulation of Tropical Storm Fred in the middle troposphere could survive passage over those mountains. The center of Tropical Storm Fred will move northwest of Haiti on Thursday. The Sea Surface Temperatures of the water northwest of Haiti are near 29°C. If the middle level circulation of Fred survives, it could spin up a new low level center of circulation when it moves back over the warm water. An upper level low near Florida will produce westerly winds that will blow toward the top of Fred’s circulation. Those winds will cause vertical wind shear and they will inhibit re-intensification of Tropical Storm Fred. If the center of Fred remains north of Cuba, it could strengthen back to a tropical storm. Fred could approach the Florida Keys and South Florida on Friday. It could move over the Gulf of Mexico during the weekend.

Hurricane Watch Issued for Florida for Tropical Storm Elsa

A Hurricane Watch was issued for a portion of the west coast of Florida because of Tropical Storm Elsa. At 5:00 a.m. EDT on Tuesday the center of Tropical Storm Elsa was located at latitude 24.1°N and longitude 82.4°W which put it about 50 miles (80 km) southwest of Key West, Florida. Elsa was moving toward the north-northwest at 12 m.p.h. (19 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 1007 mb.

A Hurricane Watch was issued for the portion of the coast from Egmont Key to Steinhatchee River, Florida. A Tropical Storm Warning was in effect for the Florida Keys from Craig Key to the Dry Tortugas. A Tropical Storm Warning was also in effect for the portion of the coast from Flamingo to Ochlockonee River, Florida. That warning included Naples, Ft. Myers, Tampa, St. Petersburg and Tampa Bay. Tropical Storm Warnings remained in effect for the Cuban provinces of Matanzas, Mayabeque, Havana and Artemisa. A Tropical Storm Watch was in effect for the portion of the coast from Ochlockonee River to Indian Pass, Florida. A Tropical Storm Watch was issued for the portion of the coast from the Mouth of the St. Marys River, Georgia to the South Santee River, South Carolina.

The center of Tropical Storm Elsa was southwest of Key West, Florida on Tuesday morning. The National Weather Service office in Key West reported a wind gust of 47 m.p.h. (76 km/h). The distribution of thunderstorms around Elsa continued to be asymmetrical. The strongest thunderstorms were occurring in bands on the eastern side of Tropical Storm Elsa. Bands on the western side of the storm consisted primarily of showers and lower clouds. Storms near the center or Elsa generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 70 miles from the center of circulation.

Tropical Storm Elsa will move through an environment somewhat favorable for intensification during the next 18 hours. Elsa will move over water where the Sea Surface Temperatures are near 29°C. It will move under the western end of an upper level ridge. The ridge will produce southwesterly winds that will blow toward the top of Tropical Storm Elsa. Those winds will cause some vertical wind shear that will inhibit intensification. However, the southwesterly winds may also increase upper level divergence to the northeast of Elsa. Additional upper level divergence could cause the surface pressure to decrease on Tuesday. Tropical Storm Elsa could intensify on Tuesday and there is a chance that Elsa could strengthen to a hurricane.

Tropical Storm Elsa will move around the western end of the subtropical high pressure system over the Atlantic Ocean during the next several days. The high will steer Elsa toward the north on Tuesday. Tropical Storm Elsa will turn toward the northeast on Wednesday when it reaches the westerly winds in the middle latitudes. On its anticipated track the center of Elsa will pass west of the Key West on Tuesday morning. The center of Tropical Storm Elsa could pass west of Tampa on Tuesday night. The stronger winds and heavy rain will occur on the eastern side of Elsa. Heavy rain could cause flash floods in some locations. Winds pushing water toward the coast could cause a storm surge of up to six feet (two meters) in Tampa Bay. Tropical Storm Elsa could cause a storm surge of 2 to 5 feet (0.6 to 1.6 m) in the Florida Keys and along the west coast of Florida. A higher storm surge could occur near where the center of Elsa makes landfall. Gusty winds could cause power outages in the Florida Keys and on the Florida peninsula. Elsa will continue to drop heavy rain over parts of Cuba as rainbands on the southern side of the circulation move across the regions
