Laura is moving toward the west near 21 mph (33 km/h) and a generally west-northwestward motion 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 and Puerto Rico this morning, near or over Hispaniola this afternoon and tonight, and near or over eastern Cuba Sunday and Sunday night. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Slow strengthening is expected during the next few days. Tropical-storm-force winds extend outward up to 205 miles (335 km) mainly to the north of the center. The estimated minimum central pressure based on surface observations 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 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.
