DISCUSSION AND OUTLOOK

———————-

At 1100 AM AST (1500 UTC), the center of Hurricane Jerry was located near latitude 16.8 North, longitude 54.4 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 east of the southeastern Bahamas on Sunday.

Maximum sustained winds have increased to near 75 mph (120 km/h) with higher gusts. Jerry is forecast to strengthen during the next day before some weakening begins this weekend.

Hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm-force winds extend outward up to 45 miles (75 km).

An Air Force Reserve Hurricane Hunter aircraft recently reported a minimum central pressure of 988 mb (29.18 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.
