Hurricane Hunters found late Thursday evening that Jerry had strengthened to a Category 2 storm.
As of 11 p.m. Thursday, Jerry was about 385 miles east of the northern Leeward Islands.
Jerry, the 10th named storm of this year's Atlantic hurricane season, was moving west-northwest at 16 mph and packing 105 mph winds with higher gusts.
A west-northwest to northwest motion at a decreasing forward speed is expected over the next few days. On the forecast track, the center of Jerry will move north of the northern Leeward Islands Friday, pass well north of Puerto Rico on Saturday and be well east-northeast of the southeastern Bahamas on Sunday.
A gradual weakening trend is forecast to begin by late Friday.
Hurricane-force winds extend outward up to 25 miles from the center and tropical-storm-force winds extend outward up to 80 miles.
A Tropical Storm Watch is in effect for:
- St. Maarten
- St. Martin
- St. Barthelemy
- Saba and St. Eustatius
A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within 36 hours.
Meanwhile, Tropical Depression Imelda is expected to dump up to 25 inches of rain in three days over parts of eastern Texas and Louisiana, according to the National Weather Service.
