Tropical Storm Isaias is bringing torrential rainfall, high winds and frequent lightning strikes to Puerto Rico Thursday morning. It had maximum sustained winds of 50 miles per hour (80 kph) and was moving west northwest at 20 miles per hour (32 kph).
Tropical Storm Warnings are in effect from parts of the U.S and British Virgin Islands, through Puerto Rico, into the Dominican Republic and Haiti, as well as parts of the Turks and Caicos Islands and the Bahamas.
The NHC warns that part of the region could see 75-150 mm of rainfall, and as much as 250 mm in the worst-affected areas, along with risky storm surge and strong winds. Floridians should continue to monitor the progress of Isaias and plan accordingly while listening to their local emergency managers. Still other models are having Isaias veering northeast in the deep Atlantic Ocean, away from any shore, he said.
The newly formed Tropical Storm Isaias is heading toward SC. It may pose a threat to the United States coastline this weekend or early next week, but questions remain about its eventual track.
Isaias was centered about 165 miles (265 kilometers) southeast of Puerto Plata, Dominican Republic late Thursday morning, according to the U.S. National Hurricane Center.
Isaias is forecast to be near the Central Bahamas Friday night and approach the Northwest Bahamas or southern Florida Friday night and Saturday. "Model forecasts are showing a complex evolution of the tropical cyclone during the next day or two".
Based on the latest forecast track, forecasters are expecting the center of Tropical Storm Isaias to move over Hispaniola on Thursday, near the southeastern Bahamas by early Friday and close to southern Florida on Saturday. The storm is predicted to drench Florida over the weekend.
"On its current forecast track, the probability for any significant and/or direct impacts from the storm system across our region is low", experts at the the National Weather ServiceCharleston said in their Thursday morning update.
"Isaias is expected to move across Hispaniola, as the storm's interaction with the mountainous island should cause some weakening and disruption to the circulation".
