Tropical Storm Isaias to Hit Florida Saturday as Hurricane, Forecasters Predict VOA News Tropical Storm Isaias could strengthen into a hurricane and threaten the East Coast after battering Puerto Rico and the Dominican Republic, according to U.S. forecasters. The [1]U.S. National Hurricane Center(NHC) has issued a tropical storm watch for parts of Florida's east coast, and the government of the Bahamas issued a similar warning for swaths of its territory. Other areas under a tropical storm watch or warning include parts of Haiti, the Dominican Republic, and the Turks and Caicos Islands. A tropical storm warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A tropical storm watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Isaias was moving northwest at 32 kmh (20 mph), and its center was expected to hit the southeastern Bahamas by late Thursday night, according to the NHC. The latest forecast map showed Isaias striking the Florida coast as a hurricane Saturday afternoon and working its way up the Atlantic seaboard. References 1. https://www.nhc.noaa.gov/#Isaias .
