DISCUSSION AND OUTLOOK ---------------------- At 800 PM AST (0000 UTC), the center of Tropical Storm Laura was located near latitude 16.8 North, longitude 62.6 West. Laura is moving toward the west near 17 mph (28 km/h), and a generally west-northwestward motion at a slightly faster forward speed is expected over the next few days. On the forecast track, the center of Laura will move near or over portions of the Leeward Islands tonight, near or over Puerto Rico Saturday morning, and near the northern coast of Hispaniola Saturday night and early Sunday. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Some slow strengthening is forecast during the next few days. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Laura is expected to produce 3 to 6 inches of rain over Puerto Rico and the Virgin Islands, the Dominican Republic, the southern Haitian Peninsula and eastern Cuba through Sunday. Maximum amounts up to 8 inches are possible along eastern portions and the southern slopes of Puerto Rico, as well as over Haiti, the Dominican Republic and eastern Cuba. This heavy rainfall could lead to flash and urban flooding, as well as an increased potential for mudslides with minor river flooding in Puerto Rico. 1 to 3 inches of rain with isolated maximum totals of 5 inches is expected over the remainder of Haiti, the northern Leeward Islands, the Turks and Caicos and southeast Bahamas. WIND: Tropical storm conditions are expected within portions of the warning area area through Saturday. Tropical storm conditions are possible within portions of the watch area Saturday night and early Sunday. SURF: Swells generated by Laura are affecting portions of the northern Leeward Islands.
