The NHC cautioned that Isaias could produce 4 to 8 inches of rain across the Dominican Republic, the Bahamas, Turks and Caicos, and northern Haiti. The NHC estimated Isaias should reach the southern tip of Florida by Saturday at 8 pm EDT. Tropical storm warnings were issued for parts of the Florida Peninsula, including Miami, Fort Lauderdale, and West Palm Beach, while a hurricane watch was put in effect from Deerfield Beach to the Volusia-Brevard County line. Tropical storm conditions are anticipated to reach the eastern coast of the state on Saturday, August 1. The eastern Carolinas could face heavy rains associated with Isaias by early next week, with possible isolated flash and urban flooding, as the hurricane moves up the east coast.

The Federal Emergency Management Agency (FEMA) provides guidance for individuals impacted by the inclement weather brought about by Hurricanes. It’s important to remember that flash floods can develop with little to no warning. It is imperative that individuals seek higher ground, and to avoid walking or driving in flood waters. Individuals should heed the warnings of local authorities and remain safe as Hurricane Isaias approaches. The Hagerty Blog Team will continue providing information and updates.
