Heavy rainfall from Tropical Storm Dolly could affect the Leeward Islands, Virgin Islands, Puerto Rico, and Hispaniola starting late Saturday into Monday. The NHC warns that this rain may lead to flash flooding, particularly in areas with higher terrain. While Dolly is forecast to weaken into a tropical wave, its precipitation could still pose risks to communities in the Caribbean. Residents in these areas should remain alert to potential flooding and monitor updates from local authorities.
