Hurricane Dorian bore down on the northern Bahamas on Saturday with howling winds, surging seas and a threat of torrential rains, forcing some evacuations and hotel closures ahead of the fierce Category 4 storm. Forecasters expected Dorian, packing 150 mph (240 kph) winds, to hit some Bahamian islands Sunday before heading near Florida and then skirting along or off the U.S. Southeast seacoast. The projected turn north in the coming days could spare the U.S. a direct hit, but would still threaten Florida, Georgia and the Carolinas with powerful winds and rising ocean water that could cause potentially deadly flooding. Over two or three days, the hurricane could dump as much as 4 feet (1 meter) of rain, unleash devastating winds and whip up a dangerous storm surge, said private meteorologist Ryan Maue and some of the most reliable computer models. Bahamas Prime Minister Hubert Minnis warned that Dorian is a "dangerous storm," saying that people "who do not evacuate are placing themselves in extreme danger and can expect a catastrophic consequence."
