Hurricane Leslie Dawdles as Bermuda Braces

The U.S. Coast Guard is warning East-Coast boaters to use "extreme caution" through the weekend.

Officials in Bermuda urged residents to "prepare for the worst" as Hurricane Leslie headed toward the British territory, bringing with it powerful winds and heavy rain.

Meanwhile, the storm's effects were already being felt as far away as the U.S. East Coast, where forecasters issued warnings for life-threatening rip currents spawned by the distant storm.

In Bermuda, schools prepared to close Friday as residents got ready for the approaching storm.

"Leslie could be a historic storm for Bermuda as it is very large and forecast to intensify rapidly as it approaches," Bermuda's Emergency Measures Organization said in a statement. "The island could experience hurricane force winds for a sustained period of time, possibly up to two days."

The storm seemed to stall Thursday, moving just 10 miles (16 kilometers) since earlier in the day, the National Hurricane Center said. The storm was about 430 miles south-southeast of Bermuda, moving at 2 mph (3 kph), the center said.
