DISCUSSION AND OUTLOOK
———————-
At 500 PM AST (2100 UTC), the eye of Hurricane Sam was located by an Air Force Hurricane Hunter aircraft near latitude 23.6 North, longitude 60.9 West. Sam is moving toward the northwest near 14 mph (22 km/h), and a turn toward the north-northwest with an additional increase in forward speed is expected tonight. A turn toward the north is anticipated on Friday, and a northeastward motion is forecast to begin on Saturday. On the forecast track, the core of Sam will pass to the east of Bermuda early Saturday.

Maximum sustained winds are near 145 mph (230 km/h) with higher gusts. Sam is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are expected during the next couple of days, but Sam is forecast to remain a major hurricane into Saturday, with more significant weakening anticipated later in the weekend.

Hurricane-force winds extend outward up to 60 miles (95 km) from the center, and tropical-storm-force winds extend outward up to 150 miles (240 km). The minimum central pressure reported by the Hurricane Hunters is 938 mb (27.70 inches).

HAZARDS AFFECTING LAND
———————-
WIND: Tropical storm conditions are expected on Bermuda beginning Friday night or early Saturday.

SURF: Swells generated by Sam will impact the northern Leeward Islands and the Greater Antilles, including Puerto Rico, during the next few days. Swells are expected to reach Bermuda and the Bahamas by Friday, and then spread to the United States east coast by this weekend. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
