DISCUSSION AND OUTLOOK ---------------------- At 500 AM AST (0900 UTC), the center of Tropical Storm Peter was located near latitude 19.1 North, longitude 59.5 West. Peter is moving toward the west-northwest near 14 mph (22 km/h). This general motion is expected to continue during the next couple of days, followed by a turn to the northwest with a decrease in forward speed on Wednesday. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Slow weakening is forecast during the next several days. Tropical-storm-force winds extend outward up to 125 miles (205 km), primarily to the northeast of the center. The estimated minimum central pressure is 1006 mb (29.71 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 through Tuesday. This rainfall may lead to areas of urban and small stream flooding. SURF: Swells generated by Peter are expected to affect the northern Leeward Islands early this week, and then reach the Bahamas by midweek. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
