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 18.6 North, longitude 58.5 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. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 50 mph (85 km/h) with higher gusts. Some gradual weakening is forecast during the next several days. Tropical-storm-force winds extend outward up to 140 miles (220 km) primarily to the northeast of the center. The estimated minimum central pressure is 1004 mb (29.65 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. NEXT ADVISORY ------------- Next complete advisory at 500 AM AST. $$ Forecaster Reinhart |
