DISCUSSION AND OUTLOOK ---------------------- At 200 AM AST (0600 UTC), the center of Tropical Storm Laura was located by surface observations over southern Dominican Republic near latitude 18.6 North, longitude 70.1 West. Laura is moving toward the west-northwest near 16 mph (26 km/h), and this general motion is expected over the next few days. On the forecast track, the center of Laura will move across Hispaniola today, be near or over Cuba Sunday night and Monday, and over the southeastern Gulf of Mexico Monday night and Tuesday. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. No significant changes in strength are forecast during the next 36 to 48 hours while Laura moves near or over Hispaniola and Cuba. Strengthening is forecast once Laura moves into the Gulf of Mexico Monday night and Tuesday. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Laura is expected to produce the following rainfall accumulations through Tuesday: Dominican Republic and Haiti: 4 to 8 inches, with maximum amounts of 12 inches across southern areas. Cuba: 3 to 6 inches, with isolated amounts of 8 inches. This heavy rainfall could lead to life-threatening flash and urban flooding, and the potential for mudslides across the Greater Antilles. Widespread minor to potentially moderate river flooding is still possible in Puerto Rico today. Rainfall amounts of 1 to 3 inches, with isolated maximum totals of 5 inches, is expected over the Turks and Caicos, southeast Bahamas and Jamaica. WIND: Tropical storm conditions are expected within portions of the warning area through Sunday night. Tropical storm conditions are possible within portions of the watch area on Monday. SURF: Swells generated by Laura are affecting portions of the Virgin Islands, Puerto Rico, and Hispaniola. These swells are expected to spread across Cuba, much of the Bahamas, and the Florida Keys during the next few days. Please consult products from your local weather office.
