DISCUSSION AND OUTLOOK ---------------------- At 200 AM AST (0600 UTC), the center of Tropical Storm Dorian was located by an Air Force Reserve Unit Hurricane Hunter aircraft near latitude 13.2 North, longitude 60.2 West. Dorian is moving toward the west-northwest near 13 mph (20 km/h), and this motion is expected to continue through tonight, followed by a turn toward the northwest on Wednesday. On the forecast track, the center of Dorian is expected to move across the Windward Islands and into the eastern Caribbean Sea during the next several hours. Dorian is forecast to pass near or south of Puerto Rico on Wednesday, move near or over eastern Hispaniola Wednesday night, and move north of Hispaniola on Thursday. Maximum sustained winds remain near 50 mph (85 km/h) with higher gusts. Some strengthening is forecast during the next 48 hours, and Dorian is forecast to be a hurricane when it moves near Puerto Rico and eastern Hispaniola. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center. The estimated minimum central pressure based on data from the Air Force Hurricane Hunters and surface observations is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- Rainfall: Dorian is expected to produce total rain accumulations of 3 to 8 inches in the Windward Islands from Martinique south to St. Vincent. Isolated maximum totals of 10 inches are possible across the northern Windward Islands. Rainfall totals of 1 to 3 inches are expected from the Grenadines, south to Grenada and across Dominica. Rainfall totals of 2 to 4 inches with maximum totals of 6 inches are possible across Puerto Rico and St. Croix. WIND: Tropical storm conditions are occurring in portions of the tropical storm warning area and these conditions are expected to continue during the next several hours.
