DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ The broad circulation of Erika is gradually moving inland over Haiti, and at 800 PM EDT (0000 UTC), the center of Tropical Storm Erika was estimated near latitude 18.3 North, longitude 72.0 West. Erika is moving toward the west near 21 mph (33 km/h). A turn toward the west-northwest or northwest is expected tonight, with this motion continuing with a decrease in forward speed through Sunday. On the forecast track, the center of Erika will move over western Haiti and the Gulf of Gonave early Saturday and will be near the southeastern Bahamas or eastern Cuba on Saturday afternoon. Maximum sustained winds are near 45 mph (85 km/h) with higher gusts. Erika is forecast to weaken to a tropical depression on Saturday, but there is a good possibility that Erika could even degenerate into a trough of low pressure while it is moving over the high terrain of Hispaniola and eastern Cuba. Tropical storm force winds extend outward up to 140 miles (220 km) to the east of the center. Barahona in the western portion of the Dominican Republic is reporting wind gusts to 40 mph (65 km/h). The estimated minimum central pressure, based on observations from the Dominican Republic and Haiti, is 1008 mb (29.77 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions across portions of the Dominican Republic are gradually subsiding. Tropical storm conditions are expected to spread across Haiti, the Turks and Caicos Islands and the southeastern Bahamas tonight, and the central Bahamas on Saturday. Tropical storm conditions are possible over eastern Cuba on Saturday and in the northwestern Bahamas by Saturday night. RAINFALL: Erika is expected to produce total rainfall accumulations of 3 to 6 inches with maximum amounts of 10 inches possible across portions of the Dominican Republic and Haiti, the Turks and Caicos Islands, eastern Cuba, and the southeastern and central Bahamas through Saturday. An additional 1 to 2 inches are expected in Puerto Rico. These rains could cause life-threatening flash floods and mud slides.
