At 5 p.m. AST, the center of Tropical Storm Isaias (pronounced “ees-ah-EE-ahs”) was located about 155 miles (250 km) west-northwest of Punta Cana, Dominican Republic.
It’s moving toward the northwest near 20 mph (31 km/h) and a 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 near the Southeastern Bahamas by late tonight. Isaias is forecast to be near the Central Bahamas Friday night and move near or over the Northwest Bahamas and near South Florida on Saturday.
Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Tropical-storm-force winds extend outward up to 240 miles (390 km) from the center. Strengthening is forecast to take place during the next day or so, and Isaias is forecast to become a hurricane on Friday or Friday night.
Isaias is expected to produce the following rain accumulations:
– Puerto Rico, Dominican Republic and northern Haiti: 4 to 8 inches, with isolated maximum totals of 12 inches.
– Bahamas, Turks and Caicos: 4 to 8 inches.
– Cuba: 1 to 2 inches, with isolated maximum totals of 4 inches.
These rainfall amounts will lead to life-threatening flash flooding and mudslides, as well as river flooding. Urban and small stream flooding is expected for the U.S. Virgin Islands, eastern and southwestern Puerto Rico, and Hispaniola.Heavy rains associated with Isaias may begin to affect eastern Florida over the weekend. This rain could result in isolated flash and urban flooding, especially in low-lying and poorly drained areas.
