DISCUSSION AND OUTLOOK ---------------------- At 200 PM AST (1800 UTC), data from an Air Force Reserve reconnaissance aircraft and the Martinique radar indicate that the center of Tropical Storm Dorian has reformed farther north near latitude 15.0 North, longitude 62.0 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 will move across the eastern and northeastern Caribbean Sea during the next few days, passing near or south of Puerto Rico on Wednesday, move near or over eastern Hispaniola Wednesday night, and move north of Hispaniola on Thursday. On Thursday night and Friday, the center of Dorian is forecast to move near the Turks and Caicos and southeastern Bahamas. Maximum sustained winds remain near 50 mph (85 km/h) with higher gusts. Slow strengthening is forecast during the next 48 hours, and Dorian is forecast to be near hurricane strength when it moves close to 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 reconnaissance aircraft is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Dorian is expected to produce the following rain accumulations through Thursday: Martinique to Saint Vincent...3 to 6 inches, isolated 10 inches. Grenadines to Grenada...1 to 3 inches. Guadeloupe to Dominica...1 to 4 inches. Puerto Rico and Dominican Republic...4 to 6 inches, isolated 8 inches. U.S. Virgin Islands...1 to 3 inches, isolated 4 inches. This rainfall may cause life-threatening flash floods. WIND: Tropical storm conditions are diminishing over the Lesser Antilles. Tropical storm conditions are expected and hurricane conditions are possible in Puerto Rico on Wednesday and in portions of the Dominican Republic late Wednesday and Thursday. SURF: Swells generated by Dorian should gradually subside in the Lesser Antilles by this evening. Swells are expected to increase along the southern coasts of Puerto Rico and Hispaniola on Wednesday and they could cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 500 PM AST. $$ Forecaster Stewart |
