DISCUSSION AND OUTLOOK
———————-
At 500 PM AST (2100 UTC), the eye of Hurricane Jerry was located near latitude 17.5 North, longitude 55.8 West. Jerry is moving toward the west-northwest near 17 mph (28 km/h). 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.
Satellite and Air Force Hurricane Hunter data indicate that
maximum sustained winds have increased to near 90 mph (150 km/h)
with higher gusts. Jerry could strengthen during the next day or so
before weakening is anticipated by this weekend.
Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 80 miles (130 km).
The estimated minimum central pressure is 979 mb (28.91 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, and Anegada. This rainfall may produce life-threatening flash floods. Jerry is forecast to produce total rainfall accumulations of 1 to 2 inches with maximum amounts of 3 inches across the the Virgin Islands and Puerto Rico.
SURF: Swells generated by Jerry are beginning to affect portions of the northern Leeward Islands. These swells are likely to cause life-threatening surf and rip current conditions.
