The north Bahamas town of Marsh Harbour has been devastated by Dorian, with more than 60% of homes damaged by the storm, the country's Prime Minister Hubert Minnis said at a press conference in the capital Nassau on Tuesday.
Speaking at the National Emergency Management Agency (NEMA) headquarters, Minnis added that "a community outside Treasure Cay, Cooperstown, has been cut off from (the) main population, at least 30 people (are) trapped in the community and were waving yellow flags, sheets, shirts, to bring attention to their survival."
"Our urgent task will be to provide food, water, shelter, safety and security," Minnis said. "Additional food will be delivered by NEMA tomorrow."
The Prime Minister said that Dorian was "the greatest national crisis in our country's history."
