According to the NHC Advisory 7A, Isaias is moving toward the northwest near 18 mph (30 km/h), and a west-northwestward to northwestward motion with some decrease in forward speed is expected over the next couple of days. On the forecast track, the center of Isaias will move over Hispaniola late today and near the Southeastern Bahamas by early Friday.
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Some weakening is likely when the center moves over Hispaniola with some re-strengthening expected by Friday.
Tropical-storm-force winds extend outward up to 345 miles (555 km) mainly to the northeast of the center. A Weatherflow station on Culebra recently reported sustained winds of 45 mph (72 km/h) with gusts to 53 mph (85 km/h).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions will continue across portions of the Leeward Islands, the U.S. and British Virgin Islands and Puerto Rico through tonight. These conditions are forecast to reach portions of the Dominican Republic and Haiti within the warning area by late tonight or early Thursday, and the southeastern Bahamas and Turks and Caicos Thursday afternoon. Tropical storm conditions are expected in the Central Bahamas beginning Friday morning and are possible in the northwestern Bahamas beginning late Friday.
RAINFALL: The disturbance is expected to produce the following rain accumulations:
Across the northern Leeward Islands, British and U.S. Virgin Islands: 3 to 6 inches.
Across Puerto Rico: 3 to 6 inches, with isolated maximum totals of 10 inches.
Across the Dominican Republic, northern Haiti and the Turks and Caicos: 3 to 6 inches, with isolated maximum totals of 8 inches.
Across the Inagua Islands: 4 to 8 inches, with isolated totals of 12 inches.
These rainfall amounts could lead to life threatening flash flooding and mudslides, as well as potential riverine flooding.
SURF: Swells generated by Isaias will be affecting portions of the Leeward Islands, the Virgin Islands, and Puerto Rico through Thursday. These swells are forecast to reach the north coast of the Dominican Republic, the Turks and Caicos Islands and the southeastern Bahamas tonight or Thursday. These swells are likely to cause life-threatening surf and rip current conditions.
