Hurricane Floyd on Saturday whirred away from the Caribbean's Leeward Islands, but forecasters warned that Puerto Rico and the Virgin Islands could be hit by heavy rains and flooding.
The hurricane itself was likely to pass well north of the islands, meteorologists said. Floyd was unlikely to hit land soon.
The hurricane center said there was a 10 percent possibility that Floyd could pass within 65 miles of Miami by Tuesday afternoon.
The Atlantic season's sixth tropical storm, Floyd formed Wednesday and reached hurricane strength Friday. At 11 p.m. Saturday, Floyd was centered about 310 miles northeast of San Juan, Puerto Rico's capital. It was expected to move west-northwest at 12 mph.
