The storm, which was forecast to reach Florida as a hurricane by Monday, dumped 9 inches (23 centimeters) of rain on Dominica late Wednesday, followed by another 6 inches (15 centimeters) early Thursday, according to the weather service in the nearby island of Antigua.
Police Superintendent Daniel Carbon said three of the deaths occurred during a mudslide in the southeast of the island. Authorities recovered the bodies of an elderly blind man and two children from the home.
