Hurricane Earl is moving rapidly toward the northeast near 35 mph, the National Hurricane Center said.
Earl is about 380 miles south of Cape Race Newfoundland with maximum sustained winds of 105 miles an hour.
The NHC said Earl, currently a Category 2 storm, is forecast to become a powerful hurricane-force extratropical low on Saturday afternoon, and "weakening is expected during the next few days, and Earl's winds are likely to fall below hurricane force tonight or early Sunday."
Earl is the fifth named system of the hurricane season and is not forecast to impact the U.S.
