DISCUSSION AND OUTLOOK

At 500 PM AST (2100 UTC), the eye of Hurricane Sam was located near latitude 30.0 North, longitude 61.8 West. Sam is moving toward the north near 20 mph (31 km/h). A turn toward the north-northeast, at a slightly slower forward speed, is expected by tonight, followed by a northeastward motion Saturday night through Monday. On the forecast track, the center of Sam will pass well to the east of Bermuda tonight.

Maximum sustained winds are near 150 mph (240 km/h) with higher gusts. Sam is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Although fluctuations in intensity are still possible, weakening is forecast during the next couple of days. However, Sam is expected to remain a major hurricane through at least Saturday night.

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). The estimated minimum central pressure is 937 mb (27.67 inches).

HAZARDS AFFECTING LAND

SURF: Swells generated by Sam will impact the northern Leeward Islands, the Greater Antilles, the Bahamas, and Bermuda during the next couple of days. Swells are expected to reach the United States east coast and Atlantic Canada on Saturday. These swells could cause life-threatening surf and rip current conditions.
