Rafael Intensifies to a Hurricane Near Cayman Islands

Former Tropical Storm Rafael intensified to a hurricane near the Cayman Islands on Tuesday evening.  At 10:00 p.m. EST on Tuesday the center of Hurricane Rafael was located at latitude 19.7°N and longitude 80.4°W which put the center about 60 miles (95 km) east-northeast of Grand Cayman.  Rafael was moving toward the northwest at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (150 km/h).  The minimum surface pressure was 985 mb.

A Hurricane Warning was in effect for Grand Cayman, Little Cayman, and Cayman Brac.  A  Hurricane Warning was in effect for the Cuban provinces of Pinar del Rio, Artemisa, La Habana, Mayabeque, Matanzas, and the Isle of Youth.

A Tropical Storm Warning was in effect for the Cuban provinces of Villa Clara, Cienfuegos, Sancti Spiritis, and Ciego de Avila.

A Tropical Storm Watch was in effect for the Florida Keys from Key West to Channel 5 Bridge.  A Tropical Storm Watch was in effect for the Dry Tortugas.  A Tropical Storm Watch was in effect for the Cuban provinces of Camaguey and Las Tunas.

Former Tropical Storm Rafael intensified to a hurricane on Tuesday evening.  A circular eye with a diameter of 15 miles (17 km) formed at the center of Rafael’s circulation.  The eye was surrounded by a 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 Rafael.  Storms near the core of Rafael generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease.

Winds to hurricane force extended out 20 miles (30 km) in the northeastern quadrant of Hurricane Rafael.  Wind to tropical storm force extended out 115 miles (185 km) in the eastern side of Rafael’s circulation.  Winds to tropical storm force extended out 60 miles (95 km) in the western side of Hurricane Rafael.

Hurricane Rafael will move through an environment favorable for intensification during the next 24 hours.  Rafael will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge over the Caribbean Sea.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Hurricane Rafael will intensify during the next 24 hours.  Rafael could intensify rapidly at times.

Hurricane Rafael will move around the southwestern part of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Rafael toward the northwest during the next 24 hours.  On its anticipated track, the center of Hurricane Rafael will move away from the Cayman Islands.  Rafael is likely to reach western Cuba by Wednesday afternoon.

Hurricane Rafael will continue to bring strong winds and heavy rain to the Cayman Islands for the next few hours.  Heavy rain could cause floods in some locations. Rafael could also cause a storm surge of up to 7 feet (2 meters) in the Cayman Islands.  Hurricane Rafael will bring strong winds and heavy rain to western Cuba.  Strong winds could cause widespread electricity outages in Cuba.  Heavy rain could cause flash floods in some locations.  Rafael could cause a storm surge of up to 10 feet (3 meters) along the south coast of western Cuba.

Tropical Storm Rafael Brings Wind and Rain to Jamaica

Tropical Storm Rafael was bringing wind and rain to Jamaica on Tuesday morning.  The center of Rafael was just southwest of Jamaica.  At 7:00 a.m. EST on Tuesday the center of Tropical Storm Rafael was located at latitude 17.4°N and longitude 78.4°W which put the center about 80 miles (130 km) south-southwest of Montego Bay, Jamaica.  Rafael was moving toward the northwest at 13 m.p.h. (20 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.

Tropical Storm Rafael was strengthening on Tuesday morning as it passed near Jamaica.  The inner end of a rainband wrapped around the western and southern sides of the center of Rafael’s circulation.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Rafael.  Storms near the center of Rafael generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speeds around Tropical Storm Rafael was asymmetrical.  Winds to tropical storm force extended out 105 miles (165 km) in the eastern side of Rafael’s circulation.  The winds in the western side of Tropical Storm Rafael were blowing at less than tropical storm force.

Tropical Storm Rafael will move through an environment favorable for intensification during the next 24 hours.  Rafael will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge over the Caribbean Sea.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear. Tropical Storm Rafael will intensify during the next 24 hours.  Rafael could intensify rapidly at times.  Tropical Storm Rafael is likely to strengthen to a hurricane by Tuesday night.

Tropical Storm Rafael will move around the southwestern part of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Rafael toward the northwest during the next 24 hours.  On its anticipated track, the center of Tropical Rafael will reach the Cayman Islands by Tuesday night.  Rafael is likely to reach western Cuba by Wednesday afternoon.

Tropical Storm Rafael will continue to bring strong winds and heavy rain Jamaica for the rest of Tuesday.  Heavy rain is likely to cause floods in some locations.  Rafael is likely to be a hurricane when it moves over the Cayman Islands.  Rafael will bring strong winds and heavy rain to the Cayman Islands.  It could also cause a storm surge of up to 7 feet (2 meters) in the Cayman Islands.  Rafael will be a hurricane when it reaches western Cuba.  Strong winds could cause widespread electricity outages in Cuba.  Heavy rain could cause flash floods in some locations.

Tropical Storm Rafael will bring strong winds and heavy rain Jamaica. Heavy rain is likely to cause floods in some locations.  Rafael is likely to be a hurricane when it moves over the Cayman Islands.  Rafael will bring strong winds and heavy rain to the Cayman Islands.  It could also cause a storm surge of up to 7 feet (2 meters) in the Cayman Islands.

Hurricane Oscar Brings Wind and Rain to Eastern Cuba

Hurricane Oscar brought wind and rain to eastern Cuba on Sunday night.  At 8:00 p.m. EDT on Sunday the center of Hurricane Oscar was located at latitude 20.2°N and longitude 74.5°W which put the center about 45 miles (75 km) east of Guantanamo, Cuba.  Oscar was moving toward the west-southwest at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 988 mb.

Hurricane Warnings are in effect for the North Coast of Cuban province of Holguin and the North Coast of Cuban province of Guantanamo to Punta Maisi.

A Hurricane Watch is in effect for the North Coast of Cuban province of Las Tunas.

Tropical Storm Warnings are in effect for the Southeastern Bahamas.  Tropical Storm Warnings are in effect for the South Coast of Cuban province of Guantanamo and the North Coast of Cuban province of Las Tunas.

A Tropical Storm Watch is in effect for the North Coast of Cuban province of Camaguey.  A Tropical Storm Watch is also in effect for the Central Bahamas.

The center of Hurricane Oscar made landfall on the coast of eastern Cuba east of Guantanamo on Sunday evening.  A very small eye with a diameter of 4 miles (6 km) was at the center of Oscar’s circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Short bands of showers and thunderstorms were revolving around the center of Hurricane Oscar.

The circulation around Hurricane Oscar was very small.  Winds to hurricane force extended out 15 miles (25 km) on the northern side of Oscar’s circulation.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Hurricane Oscar.

Hurricane Oscar will move around the southern side of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Oscar toward the west during the next 24 hours.  On its anticipated track, Hurricane Oscar will move across eastern Cuba on Sunday night and on Monday.

Hurricane Oscar will weaken to a tropical storm as it moves inland over eastern Cuba.  Even though Oscar will weaken, it will still bring strong winds and heavy rain to eastern Cuba.  Heavy rain is likely to cause flash floods in some locations.

Hurricane Oscar Develops Rapidly Southeast of the Bahamas

Hurricane Oscar developed rapidly over the Atlantic Ocean southeast of the Bahamas on Saturday afternoon.  At 2:00 p.m. EDT on Saturday the center of Hurricane Oscar was located at latitude 21.4°N and longitude 70.6°W which put the center about 165 miles (265 km) east-southeast of the Southeastern Bahamas.  Oscar was moving toward the west at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (150 km/h).  The minimum surface pressure was 989 mb.

A Hurricane Warning is in effect for the Turks and Caicos, and the Southeastern Bahamas.

A Hurricane Watch is in effect for the Cuban province of Camaguey.

A U.S. Air Force Reserve Hurricane Hunter reconnaissance plane found that a low pressure system over the Atlantic Ocean southeast of the Bahamas had rapidly developed into a hurricane on Saturday afternoon.  Based on data gather by the reconnaissance flight, the U.S. National Hurricane Center designated the system as Hurricane Oscar.

The circulation around Hurricane Oscar was very small.  A very small eye with a diameter of 4 miles (6 km) was at the center of Oscar’s circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Short bands of showers and thunderstorms were revolving around the center of Hurricane Oscar.  Storms near the center of Oscar generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Oscar was very small.  Winds to hurricane force extended out 5 miles (8 km) on the northern side of Oscar’s circulation.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Hurricane Oscar.

Hurricane Oscar will move through an environment mostly favorable for intensification during the next 24 hours.  Oscar will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the eastern end of an upper level ridge over the Bahamas.  The upper level ridge will produce northeasterly winds that will blow toward the top of Oscar’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Hurricane Oscar is likely to intensify during the next 24 hours.

Hurricane Oscar will move around the southern side of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Oscar toward the west during the next 24 hours.  On its anticipated track, Hurricane Oscar will move over the Turks and Caicos and the Southeastern Bahamas.  Oscar could approach eastern Cuba on Sunday night.

Hurricane Oscar will bring strong winds and locally heavy rain to the Turks and Caicos and the Southeastern Bahamas.  Heavy rain could cause flash floods in some locations.

Elsewhere, Tropical Storm Nadine brought strong winds and heavy rain to parts of Belize and the Yucatan Peninsula.  At 2:00 p.m. EDT on Saturday the center of Tropical Storm Nadine was located at latitude 17.6°N and longitude 88.5°W which put the center about 20 miles (30 km) west-northwest of Belize City, Belize.  Nadine was moving toward the west at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 1003 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Belize City,, Belize to Cancun, Mexico.  The Tropical Storm Warning includes Cozumel.

Tropical Storm Warnings and Watches Issued for Florida

The potential threat posed by a tropical wave over eastern Cuba prompted the issuance of Tropical Storm Warnings and Watches for parts of Florida.  The U.S. National Hurricane Center designated the tropical wave as Potential Tropical Cyclone Four in order to issue the watches and warnings.  The tropical wave was previous designated as Invest 97L.

At 11:00 a.m. EDT on Friday the center of Potential Tropical Cyclone Four was located at latitude 20.9°N and longitude 76.6°W which put the center about 90 miles (145 km) east-southeast of Camaguey, Cuba and about 420 miles (675 km) southeast of Key West, Florida.  The tropical wave was moving toward the west-northwest at 16 m.p.h. (26 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 1012 mb.

A Tropical Storm Warning was in effect for the portion of the coast from East Cape Sable to Bonita Beach, Florida.

A Tropical Storm Watch was in effect for the Florida Keys from south of Card Sound Bridge.  A Tropical Storm Watch was in effect for the portion of the coast from East Cape Sable to Card Sound Bridge, Florida.  A Tropical Storm Watch was in effect for the portion of the coast from Bonita Beach to Aripeka,, Florida. 

The tropical wave currently designated as Potential Tropical Cyclone Four will move into an environment favorable for the formation of a tropical cyclone during the next 24 hours.  Potential Tropical Cyclone Four will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southeastern part of an upper level ridge over the southeastern U.S.  The ridge will produce northeasterly winds that will blow toward the top of the tropical wave.  The winds in the lower levels of the atmosphere will also blow from the east and there will be little vertical wind shear.  The tropical wave is unlikely to develop into a tropical cyclone as long as the center of the wave is over Cuba.  A tropical depression or a tropical storm is likely to form on Saturday when Potential Tropical Cyclone Four moves north of Cuba.  The system could strengthen to a tropical storm over the eastern Gulf of Mexico.

The tropical wave is moving around the southwestern part of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Potential Tropical Cyclone Four toward the northwest during the next 24 hours.  On its anticipated track, the tropical wave will move toward the Florida Keys.  Potential Tropical Cyclone Four is likely to move toward the north during the weekend when it reaches the western end of the high pressure system.

Potential Tropical Cyclone Four is likely to bring gusty winds and locally heavy rain to Florida during the weekend.  Heavy rain could cause widespread flooding.  Potential Tropical Cyclone Four could also cause a storm surge along the west coast of Florida.

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.

Tropical Storm Eta Strengthens, Hurricane Watch for Florida

Tropical Storm Eta strengthened a little more Saturday evening and A Hurricane Watch was issued for parts of South Florida and the Florida Keys. At 10:00 p.m. EST on Saturday the center of Tropical Storm Eta was located at latitude 20.7°N and longitude 79.9°W which put it about 140 miles (220 km) west-southwest of Camaguey, Cuba. Eta was moving toward the northeast at 13 m.p.h. (20 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 991 mb.

A Hurricane Watch was in effect for the portion of the coast from Deerfield Beach to Bonita Beach, Florida and for the Florida Keys from Ocean Reef to the Dry Tortugas. A Tropical Storm Warning was in effect for the portion of the coast from the Brevard/Volusia County Line to Englewood, Florida. A Tropical Storm Warning was in effect for the Florida Keys from Ocean Reef to the Dry Tortugas. Tropical Storm Warnings were in effect for the Cayman Islands and the Cuban provinces of Camaguey, Ciego de Avila, Sancti Spiritus, Villa Clara, Cienfuegos and Matanzas. A Tropical Storm Warning was in effect for the Northwestern Bahamas including the Abacos, Andros Island, the Berry Islands, Bimini, Eleuthera, Grand Bahama Island and New Providence. A Tropical Storm Watch was in effect for the portion of the coast from Englewood to Anna Maria Island, Florida. A Tropical Storm Watch was in effect for Lake Okeechobee. A Tropical Storm Watch was in effect for the Cuban provinces of La Habana, Artemisa y Mayabeque, Pinar del Rio and the Isle of Youth.

The circulation around Tropical Storm Eta continued to strengthen on Saturday evening. There were occasional infrared satellite images that suggested a small eye could be forming at the center of Eta. There was a ring of strong thunderstorms around the center and the strongest winds were occurring in that ring of storms. Storms near the core of Eta generated upper level divergence which pumped mass away to the northeast of the tropical storm. The strongest rainbands were in the northern and eastern parts of the circulation around Tropical Storm Eta. Bands south and west of the center consisted primarily of showers and lower clouds. The strongest winds were blowing in the northern half of Eta. Winds to tropical storm force extended out 120 miles (195 km) from the center of circulation.

Tropical Storm Eta will move through an environment favorable for intensification during the few hours. Eta will move over water where the Sea Surface Temperature is near 29°C. An upper level trough over the Gulf of Mexico will produce southwesterly winds which will blow toward the top of Tropical Storm Eta. Those winds will cause moderate vertical wind shear. The shear will inhibit intensification, but it may not be strong enough to prevent Eta from getting stronger. Tropical Storm Eta is likely to weaken when it crosses Cuba on Saturday night. The Sea Surface Temperature of the water north of Cuba is near 29°C. So, Eta is likely to strengthen after it crosses Cuba. Eta could strengthen to a hurricane when it approaches the Florida Keys.

The upper level trough will make a transition to a cutoff low over the southeastern Gulf of Mexico which will be the primary feature steering Eta. Counterclockwise rotation around the cutoff low will pull Eta toward the northeast on Saturday night . On its anticipated track Eta could move across Cuba west of Camaguey on Saturday night. Tropical Storm Eta will drop heavy rain when it moves across Cuba and flash floods could occur. The upper low will steer Eta toward the northwest on Sunday. Eta will approach the Florida Keys on Sunday night. It could be a hurricane at that time. Eta will bring gusty winds and locally heavy rain to the Florida Keys and South Florida. A high pressure system over the Atlantic Ocean will interact with the circulation around the northern side of Eta to produce strong easterly winds which will blow toward the coast of Southeast Florida. Those winds will push water toward the coast and the water level could rise up to six feet (2 meters). The strong winds could also cause widespread power outages in South Florida.
