COCOA BEACH, Fla. (AP) - Heavy rain lashed the Florida coast ahead of Hurricane Floyd Tuesday night, as evacuees from Florida to the Carolinas streamed inland in bumper-to-bumper traffic to flee one of the most fearsome storms of the century. The monstrous, 600-mile storm - bigger than the whole state of Florida - threatened to roll ashore early Thursday, probably in North Carolina. Nearly 2 million people were told to get out of the way as Floyd skirted the north-central Florida coast and headed farther north. Heavy rain fell from West Palm Beach to Cape Canaveral Tuesday evening, with forecasters expecting tropical storm winds to come ashore just before dawn. There still was a chance the coast could get hit with hurricane-force winds greater than 74 mph late Wednesday morning.
