DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Tropical Storm Peter was located near latitude 19.9 North, longitude 64.7 West. Peter is moving toward the west-northwest near 9 mph (15 km/h). A west-northwest motion is expected to continue today. A turn to the north with a decrease in forward speed is expected beginning tomorrow. On the forecast track, the center of Peter is currently passing north of the Virgin Islands and Puerto Rico today and should move well east of the southeastern Bahamas during the next few days. Maximum sustained winds have decreased to near 40 mph (65 km/h) with higher gusts. Additional weakening is forecast over the next several days. Peter is expected to weaken to a tropical depression by tonight and then degenerate to a remnant low by Thursday. Tropical-storm-force winds extend outward up to 150 miles (240 km) from the center. The estimated minimum central pressure is 1008 mb (29.77 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Rainfall around the southern periphery of Tropical Storm Peter could produce additional rainfall totals of 1 to 4 inches, with storm total accumulations up to 6 inches, across portions of the Northern Leeward Islands, including portions of the Virgin Islands, as well as Puerto Rico and the northern portions of Hispaniola through Thursday morning. This rainfall may lead to areas of urban and small stream flooding. SURF: Swells generated by Peter are affecting the northern Leeward Islands and Puerto Rico, and will continue spreading westward to Hispaniola later today and the Bahamas on Wednesday. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
