On the forecast track, the center of Sam will move away from Bermuda today. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds have decreased to near 140 mph (220 km/h) with higher gusts. Sam is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Additional weakening is forecast during the next couple of days, but Sam is expected to remain a major hurricane into Sunday. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 205 miles (335 km). Several automated stations on Bermuda have recently reported wind gusts between 40 and 50 mph (65 to 80 km/h). Data from the Hurricane Hunter aircraft indicate that the minimum central pressure has risen to 945 mb (27.91 inches).

SURF: Swells generated by Sam will impact the northern Leeward Islands, the Greater Antilles, the Bahamas, and Bermuda during the next couple of days.
