Interests in the northern Leeward Islands, Virgin Islands, and Puerto Rico should monitor the progress of this system. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Tropical Storm Peter was located near latitude 19.8 North, longitude 62.8 West. Peter is moving toward the west-northwest near 12 mph (19 km/h). This general motion is expected to continue for the next day or so, followed by a turn to the northwest with a decrease in forward speed on Wednesday, and then a turn to the north by Wednesday night. On the forecast track, the center of Peter will pass north of the Virgin Islands and Puerto Rico on Tuesday. Recent satellite-derived wind data indicate that maximum sustained winds remain near 50 mph (85 km/h) with higher gusts. Slow weakening is forecast during the next few days. Tropical-storm-force winds extend outward up to 175 miles (280 km) from the center, primarily in the northeastern quadrant. 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 rainfall totals of 1 to 3 inches, with locally higher amounts possible, across portions of the Northern Leeward Islands, including the Virgin Islands, as well as Puerto Rico and the northern portions of Hispaniola through Tuesday. 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 on Tuesday and the Bahamas on Wednesday. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 500 AM AST. $$ Forecaster Reinhart
