CORE OF SAM NOW EAST-SOUTHEAST OF BERMUDA TONIGHT…SWELLS EXPECTED TO REACH THE EAST COAST OF THE U.S. AND ATLANTIC CANADA ON SATURDAY
According to the NHC Advisory 37A…Sam is moving moving just east of due north near 20 mph (31 km/h). A turn toward the north-northeast, at a slightly slower forward speed, is expected 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).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected on Bermuda beginning tonight or early Saturday.
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.

Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Victor is expected to gradually weaken over the next 72 hours. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center.
