DISCUSSION AND OUTLOOK
At 200 PM AST (1800 UTC), the eye of Hurricane Jerry was located by an Air Force Reserve Hurricane Hunter aircraft near latitude 17.2 North, longitude 55.2 West. Jerry is moving toward the west- northwest near 16 mph (26 km/h). A west-northwest motion at a similar forward speed is expected over the next few days. On the forecast track, the center of Jerry will be near or north of the northern Leeward Islands Friday, pass north of Puerto Rico on Saturday and be east of the southeastern Bahamas on Sunday.
Maximum sustained winds have increased to near 85 mph (140 km/h) with higher gusts. Jerry could strengthen during the next day before some weakening begins this weekend.
Hurricane-force winds extend outward up to 20 miles (30 km) from the center and tropical-storm-force winds extend outward up to 80 miles (130 km).
An Air Force Reserve Hurricane Hunter aircraft recently reported a minimum central pressure of 982 mb (29.00 inches).
WIND: Tropical storm conditions are possible within the watch areas by early Friday.
RAINFALL: Jerry is expected to produce 1 to 3 inches of rainfall, with isolated maximum totals of 4 to 6 inches from Barbuda northwest across St. Maarten/Anguilla into Anegada. Jerry is forecast to produce total rainfall accumulations of 1 to 2 inches with maximum amounts of 3 inches across the Virgin Islands and Puerto Rico.
SURF: Swells generated by Jerry are forecast to begin to affect portions of the northern Leeward Islands this afternoon. These swells are likely to cause life-threatening surf and rip current conditions.
