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.

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 Jamaica. 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.

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 Grace Brings Wind and Rain to Jamaica

Tropical Storm Grace brought wind and rain to Jamaica on Tuesday. At 2:00 p.m. EDT on Tuesday the center of Tropical Storm Grace was located at latitude 18.5°N and longitude 77.5°W which put it about 25 miles (40 km) east of Montego Bay, Jamaica. Grace was moving toward the west at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 1005 mb.

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

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

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

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

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

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

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