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.

Tropical Storm Elsa Crosses Cuba

Tropical Storm Elsa moved across Cuba during Monday afternoon and evening. At 11:00 p.m. EDT on Monday the center of Tropical Storm Elsa was located at latitude 23.5°N and longitude 82.3°W which put it about 80 miles (130 km) south-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 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.

The center of Tropical Storm Elsa moved across western Cuba during Monday afternoon and evening. The center passed just to the east of Havana before it moved over water north of Cuba. Tropical Storm Elsa continued to exhibit an organized circulation on satellite and radar imagery even after it spent half a day over land. A reconnaissance plane found sustained winds of 60 m.p.h. (95 km/h) over water north of Cuba. The inner end of a rainband wrapped around the eastern and northern sides of the center of Elsa. Strong thunderstorms were occurring in bands near south Florida and south of Cuba. Storms near the center of Tropical Storm Elsa generated upper level divergence that pumped mass away to the northeast of the tropical storm. Winds to tropical storm force extended out 70 miles (110 km) from the center of circulation.

Tropical Storm Elsa will move through an environment somewhat favorable for intensification during the next 24 hours. Elsa will move over water where the Sea Surface Temperatures are near 30°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. 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-northwest during the next few hours. Elsa will move more toward the north on Tuesday. On its anticipated track the center of Elsa will pass west of the Florida Keys 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

Tropical Storm Elsa Churns South of Cuba

Tropical Storm Elsa was churning south of Cuba on Monday morning. At 11:00 a.m. EDT on Monday the center of Tropical Storm Elsa was located at latitude 21.5°N and longitude 81.2°W which put it about 20 miles (35 km) east-southeast of Cayo Largo, Cuba. Elsa was moving toward the northwest at 14 m.p.h. (22 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 1006 mb.

Tropical Storm Warnings were in effect for the Florida Keys from Craig Key to the Dry Tortugas and for the portion of the coast from Flamingo to Suwannee River, Florida. The Tropical Storm Warnings included Naples, Ft. Myers, Tampa, St. Petersburg and Tampa Bay. Tropical Storm Warnings were also in effect for the Cuban provinces of Cienfuegos, Matanzas, Ciego de Avila, Sancti Spiritus, Villa Clara, Mayabeque, Havana, Artmemisa. Tropical Storm Watches were in effect for the Florida Keys from Craig Key to Ocean Reef including Florida Bay and for the portion of the coast from Suwannee River, Florida to Indian Pass, Florida.

Tropical Storm Elsa exhibited a little more organization on Monday morning. More thunderstorms formed north and east of the center of Elsa. However, the distribution of thunderstorms remained asymmetrical. The strongest thunderstorms were occurring in bands on the east side of Tropical Storm Elsa. Bands in the western half of the circulation consisted primarily of showers and lower clouds. Storms near the center generated upper level divergence that pumped mass away to the northeast of the tropical storm. Winds to tropical storm force extended out 70 miles from the center of Elsa.

Tropical Storm Elsa will move through an environment somewhat favorable for intensification during the next few hours. Elsa will move over water where the Sea Surface Temperatures are near 30°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. Tropical Storm Elsa could strengthen a little before it reaches Cuba. Elsa will weaken when the center crosses Cuba. Tropical Storm Elsa could regain some strengthen when it moves over warm water southwest of the Florida Keys, but the upper level ridge will continue to cause vertical wind shear.

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 northwest during the next few hours. On its anticipated track the center of Tropical Storm Elsa will make landfall on the south coast of Cuba southeast of Havana in a few hours. The center of Elsa will pass west of the Florida Keys 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) along the southern coast of Cuba. Tropical Storm Elsa could cause a storm surge of 2 to 4 feet (0.6 to 1.2 m) in the Florida Keys and along the west coast of Florida. A high storm surge could occur near where the center of Elsa makes landfall.

Tropical Storm Philippe Brings Wind, Rain to Cuba and South Florida

Tropical Storm Philippe brought wind and rain to parts of Cuba and south Florida on Saturday night.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Philippe was located at latitude 24.8°N and longitude 82.1°W which put it about 25 miles (40 km) northwest of Key West, Florida.  Philippe was moving toward the north-northeast at 24 m.p.h. (39 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 1003 mb.

Tropical Storm Warnings were in effect for the Cuban provinces of Isla de la Juventud, La Habana, Ciudad de la Habana, Matanzas, Cienfuegos and Villa Clara.  Tropical Storm Warnings were in effect for the northwestern Bahamas including the Abacos, Andros Island, Berry Island, Bimini, Eleuthera, Grand Bahama Island and New Providence.  Tropical Storm Watches were in effect for the portion of the coast from Craig Key to Golden Beach, Florida.  Tropical Storm Watches were also in effect for the Central Bahamas including Cat Island, the Exumas, Long Island, Rum Cay and San Salvador.

The circulation is of Tropical Storm Philippe is not well organized.  The appear to be multiple smaller centers of counterclockwise rotation moving around inside the broader circulation.  One center of circulation is in northwest of Key West.  Showers and thunderstorms were primarily northeast of that center of rotation.  There were low clouds west of that center.  Another center of rotation was just north of the coast of Cuba.  A primary band of showers and thunderstorms wrapped around the eastern side of this second center.  The middle and upper level circulation of Tropical Storm Philippe appeared to be associated with the center near Cuba.

Tropical Storm Philippe will move through an environment that will be somewhat favorable for intensification.  Philippe will move over water where the Sea Surface Temperature is near 29°C.  An upper level trough approaching Tropical Storm Philippe from the west is producing strong southwesterly winds which are causing significant vertical wind shear.  The shear is inhibiting the organization of the circulation.  Tropical Storm Philippe could intensify on Sunday if the center of circulation near Cuba becomes the dominant center, since it has a more complete vertical structure.

The upper level trough will continue to steer Tropical Storm Philippe quickly toward the northeast on Sunday.  On its anticipated track Tropical Storm Philippe will move through the Upper Florida Keys and over the Northwestern Bahamas on Sunday.   It will bring gusty winds and locally heavy rains to those areas.

Potential Tropical Cyclone Eighteen Prompts Warnings for Cuba and Bahamas

Potential Tropical Cyclone Eighteen prompted the governments of Cuba and the Bahamas to issue Tropical Storm Warnings and Watches for portions of those countries on Friday afternoon.  At 5:00 p.m. EDT on Friday the center of Potential Tropical Cyclone Eighteen was located at latitude 17.5°N and longitude 84.5°W which put it about 415 miles (670 km) south-southwest of Havana, Cuba.  It was moving toward the north-northwest at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1006 mb.

Tropical Storm Warnings were issued for the Cuban provinces of Isla de la Juventud, La Habana, Ciudad de la Habana, Matanzas, Cienfuegos, and Villa Clara.  Tropical Storm Warnings were also issued for the northwestern Bahamas including the Abacos, Andros Island, Berry Island, Bimini, Eleuthera, Grand Bahama Island and New Providence.  Tropical Storm Watches were issued for the Central Bahamas including Cat Island, the Exumas, Long Island, Rum Cay and San Salvador.

An Air Force Reserve Hurricane Hunter reconnaissance plane investigated the system formerly known as Invest 93L on Friday afternoon.  The plane found sustained winds to tropical storm force.  The plane also found a broad circulation center with several smaller centers of circulation revolving around inside the broader center.  Based on the observations from the plane, the National Hurricane Center (NHC) chose not to upgrade the system to Tropical Storm Philippe in its 5:00 p.m. EDT advisory.  However, NHC did change the designation of the system from Invest 93L to Potential Tropical Cyclone Eighteen.  If a more well defined center of circulation develops, then NHC could still change designation of the system to Tropical Storm Philippe.

The circulation of Potential Tropical Cyclone Eighteen is still organizing.  As mentioned above, there is a broad center of counterclockwise rotation.  There are also several smaller counterclockwise swirls within the broader center.  More showers and thunderstorms developed closer to the center of circulation on Friday afternoon.  The storms closer to the center of circulation were generating some upper level divergence which was pumping away mass to the northeast of the system.  Some bands of showers and thunderstorms were developing in the outer portions of the circulation.

Potential Tropical Cyclone Eighteen will move through an environment somewhat favorable for intensification.  It will move over water where the Sea Surface Temperature is near 30°C.  The system is embedded in a flow over warm moist air.  However there is a stationary front northwest of the system and there is cooler, drier air north of the stationary front.  The system is currently under the western side of an upper level ridge.  The upper level winds are weak and there is not much vertical wind shear.  Potential Tropical Cyclone Eighteen could slowly intensify during the next 24 hours as the circulation becomes more well organized.

The ridge east of Potential Tropical Cyclone Eighteen is steering the system toward the north-northwest.  That general motion should continue for another six to twelve hours.  An upper level trough will approach the system from the west on Saturday and the trough will start to steer it more toward the northeast.  On its anticipated track Potential Tropical Cyclone Eighteen will approach Cuba on Saturday afternoon.  The center of the system will move south of the Florida Keys on Saturday night and it could move across the northwestern Bahamas on Sunday.

The system will bring gusty winds and locally heavy rain to those locations.  The locally heavy rain could cause flooding.  There could be a storm surge of several feet (one to two meters) on parts of the south coast of Cuba, where the wind blows the water toward the coast.  There could also be some storm surge along the coasts of the Florida Keys.
