DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 800 AM AST (1200 UTC), the center of Tropical Storm Harvey was located near latitude 13.0 North, longitude 60.3 West. Harvey is moving toward the west near 18 mph (30 km/h), and a continued westward motion with a slight increase in forward speed is expected over the next couple of days. On the forecast track, Harvey should move through the Windward Islands and into the eastern Caribbean Sea this morning. Maximum sustained winds remain near 40 mph (65 km/h) with higher gusts. Some slight strengthening is possible during the next 48 hours. Tropical-storm-force winds extend outward up to 60 miles (95 km) mainly to the north of the center. The minimum central pressure estimated from Air Force Reserve Hurricane Hunter aircraft data is 1005 mb (29.68 inches). The Grantley Adams International Airport on Barbados recently reported a pressure of 1006 mb (29.71 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are spreading through the warning area at this time, making outside preparations difficult or dangerous. Tropical storm conditions are possible in the watch area today. RAINFALL: Harvey is expected to produce rainfall totals of 2 to 4 inches across portions of the Windward Islands from Martinique southward to Grenada. These rains could cause life-threatening flash floods and mudslides. NEXT ADVISORY ------------- Next complete advisory at 1100 AM AST. $$ Forecaster Beven
