SEBRING — Tropical Storm Isaias may turn north and sideswipe Florida, if the predictions as of Thursday morning hold true.

The probability cone presented by the National Hurricane Center at the National Oceanic and Atmospheric Administration shows the center of the storm skirting the east coast of the state from 8 p.m. Saturday and 8 a.m. Sunday.

Maximum sustained winds are near 60 mph (95 km/h) with higher gusts, NHC reported. Tropical storm force winds extend outward up to 310 miles (500 km) primarily to the north of the storm center.

As of midday Thursday, Isaias (pronounced “ees-ah-EE-ahs”) was over the ocean, centered directly north of the straits between Dominican Republic and Puerto Rico, with storm warnings in effect for Puerto Rico, the U.S. Virgin Islands, Dominican Republic, Haiti, the Turks and Caicos Islands, and the Southeastern and Central Bahamas.

Isaias was moving toward the northwest at almost 20 mph (31 km/h), with a west-northwestward to northwestward motion, and expectation that the storm would slow as the center of Isaias moved over Hispaniola and near the Southeastern Bahamas by late Thursday/early Friday.

As of Thursday, tropical storm force winds were hitting the southern coast of Puerto Rico, with reports of sustained winds of 45 mph (72 km/h) with a gust to 54 mph (87 km/h).

A wind gust of 60 mph (96 km/h) was reported at Punta Cana on the eastern tip of the Dominican Republic.

By Friday night, Isaias should be over the Central Bahamas on approach to the Northwest Bahamas or southern Florida by Friday night or early Saturday morning.

Predicted rainfall was 4 to 8 inches in the Turks and Caicos Islands; 4 to 8 inches, with maximums of 10 inches in Puerto Rico, Dominican Republic and northern Haiti, and 1 to 2 inches, with isolated highs of 4 inches, in Cuba.

Predictions were for life-threatening flash floods and mudslides, in rivers and small streams in the U.S. Virgin Islands, Puerto Rico and Hispaniola.

While Isaias may weaken Thursday from passing over Hispaniola, re-strengthening is forecast for Friday and Friday night.

The NHC predicts that tropical storm force winds will hit central Florida at 8 p.m. Saturday.

Heavy rains associated with Isaias may start affecting South Florida by Saturday morning with the possibility of isolated flash and urban flooding, especially in low-lying and poorly drained areas.
