Hurricane Dorian came to a catastrophic daylong halt over the northwest Bahamas, flooding the islands of Abaco and Grand Bahama with walls of water that lapped into the second floors of buildings, trapped people in attics and drowned the Grand Bahama airport under 6 feet of water. At least five people died and 21 injured people were airlifted to the capital by the US Coast Guard, Bahamas officials said. "We are in the midst of a historic tragedy," Prime Minister Hubert Minnis said. "The devastation is unprecedented and extensive."

Winds and rain continued to pound the northwest islands, sending people fleeing the floodwaters from one shelter to another. By Tuesday morning, the storm's top sustained winds had dipped to 120 mph (193 kph), making it a Category 3 hurricane, but it remained almost stationary. It was centered 25 miles (40 kilometers) northeast of Freeport ¿ roughly the same distance from the city as at 9 am. Hurricane-force winds extended out as far as 45 mph (75 kilometers) in some directions. Hundreds of thousands of people in Florida, Georgia and South Carolina were ordered to evacuate before the storm rolls up the Eastern Seaboard, bringing the possibility of life-threatening storm-surge flooding even if the storm's heart stays offshore, as forecast.
