Tropical Storm Karen dropped heavy rain on parts of Puerto Rico and the Virgin Islands on Tuesday. At 2:00 p.m. EDT on Tuesday the center of Tropical Storm Karen was located at latitude 17.5°N and longitude 66.0°W which put it about 65 miles (105 km) south of San Juan Puerto Rico. Karen was moving toward the north at 8 m.p.h. (13 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 1005 mb.
Tropical Storm Warnings were in effect for Puerto Rico including Vieques and Culebra, the U.S. Virgin Islands and the British Virgin Islands.
The circulation around Tropical Storm Karen exhibited more organization on Tuesday afternoon. A new low level center of circulation formed a little farther to the west near a cluster of stronger thunderstorms. The minimum surface pressure decreased by several millibars. More thunderstorms formed near the center of circulation and in bands revolving around the center. Storms near the newly reformed center of circulation were generating more upper level divergence which was pumping mass away from the tropical storm. The removal of mass was what allowed the surface pressure to decrease. Winds to tropical storm force extended out about 80 miles (130 km) from the center of circulation.
Tropical Storm Karen will move through an environment favorable for intensification during the next 24 to 48 hours. Karen will move over water where the Sea Surface Temperature is near 29°C. Karen has moved under the middle of an upper level ridge over the eastern Caribbean Sea where the upper level winds are weaker. There will be less vertical wind shear during the next day or two. The environment around Tropical Storm Karen will support intensification. However, the center of Karen will pass over Puerto Rico during the next 24 hours. The mountains in Puerto Rico will disrupt the circulation in the lower levels and Tropical Storm Karen will weaken when it passes over those mountains. Karen will likely strengthen again when it moves north of Puerto Rico.
Tropical Storm Karen will move around the western end of a subtropical high pressure system over the Atlantic Ocean. The high will steer Karen toward the north during the next day or two. On its anticipated track Tropical Storm Karen will move across Puerto Rico during the next 24 hours. Karen will drop heavy rain on parts of Puerto Rico, the U.S. Virgin Islands and the British Virgin Islands. Prolonged heavy rain will create a high risk for flash floods in those areas.
Elsewhere over the Atlantic Ocean, Tropical Storm Jerry was moving slowly toward Bermuda and Tropical Storm Lorenzo was strengthening west of the Cabo Verde Islands. At 2:00 p.m. EDT the center of Tropical Storm Jerry was located at latitude 30.9°N and longitude 69.1°W which put it about 270 miles (435 km) west-southwest of Bermuda. Jerry was moving toward the north-northeast at 7 m.p.h. (11 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 992 mb. A Tropical Storm Warning was in effect for Bermuda.
At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Lorenzo was located at latitude 12.4°N and longitude 29.3°W which put it about 270 miles (435 km) west-southwest of the Cabo Verde Islands. Lorenzo 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 997 mb
