Former Tropical Storm Larry strengthened to a hurricane over the eastern Atlantic Ocean early on Thursday. At 5:00 a.m. EDT on Thursday the center of Hurricane Larry was located at latitude 13.0°N and longitude 32.3°W which put it about 545 miles (875 km) west-southwest of the Cabo Verde Islands. Larry was moving toward the west at 20 m.p.h. (32 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 987 mb.

Former Tropical Storm Larry intensified quickly during the past 24 hours and it reached hurricane intensity early on Thursday morning. The inner end of a rainband wrapped around the center of Hurricane Larry and an eye appeared intermittently on visible and microwave satellite images. Bands of showers and thunderstorms were revolving around the center of Larry. Storms near the center generated upper level divergence that pumped mass away to the west of the hurricane. Winds to hurricane force extended out 20 miles (30 km) from the center of Larry. Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation.

Hurricane Larry will move through an environment favorable for intensification during the next several days. Larry will move over water where the Sea Surface Temperature is near 27.5˚C. It will move under the southern side of an upper level ridge over the eastern Atlantic Ocean. The ridge will produce easterly winds that will blow toward the top of Larry’s circulation. Those winds will cause some vertical wind shear. The winds in the lower levels will also blow from the east and so there will not be a lot of vertical wind shear. Hurricane Larry will strengthen during the next 48 hours and it could intensify to a major hurricane. Hurricane could undergo a period of rapid intensification once an inner core with an eye and an eyewall are fully formed.

Hurricane Larry will move around the southern side of a subtropical high pressure system over the Atlantic Ocean. The high will steer Larry toward the west during the next several days. On its anticipated track Hurricane Larry will move farther away from the Cabo Verde islands. Larry could be east of the northern Leeward Islands by the weekend.

Elsewhere, the remnants of former Hurricane Ida interacted with a slow moving cold front to cause widespread urban and flash floods in the northeastern U.S. At 5:00 a.m. EDT on Thursday the center of the remnants of former Hurricane Ida was located at latitude 41.4°N and longitude 71.6°W which put it about 40 miles (65 km) southwest of Providence, Rhode Island. Ida was moving toward the northeast at 28 m.p.h. (43 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 998 mb. There were reports of urban and flash floods in central and eastern Pennsylvania, northern New Jersey and southeastern New York including New York City. There were reports of tornadoes in Maryland and New Jersey.
