Earl is then forecast to slow down considerably Saturday night through Monday. Maximum sustained winds are near 100 mph (155 km/h) with higher gusts. Slight fluctuations in intensity are possible today. Earl is expected to complete its transition to a powerful hurricane-force extratropical low on Saturday and then steadily weaken through early Monday. Hurricane-force winds extend outward up to 80 miles (130 km) from the center and tropical-storm-force winds extend outward up to 230 miles (370 km). The estimated minimum central pressure is 961 mb (28.38 inches).

SURF: Swells generated by Earl are affecting Bermuda and portions of the U.S. East Coast and are expected to reach Nova Scotia and Newfoundland tonight and on Saturday.
