DISCUSSION AND OUTLOOK ---------------------- At 200 AM AST (0600 UTC), the center of Tropical Storm Laura was located near latitude 17.3 North, longitude 64.4 West. Laura is moving toward the west-northwest near 18 mph (30 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 Virgin Islands during the next several hours, near or over Puerto Rico later today, and near the northern coast of Hispaniola tonight and 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 205 miles (335 km) from the center. The estimated minimum central pressure is 1008 mb (29.77 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 northern Leeward Islands, the Turks and Caicos and southeast Bahamas. WIND: Tropical storm conditions are expected within portions of the warning area area this morning through Sunday.
