SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Bermuda A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 200 AM AST (0600 UTC), the eye of Hurricane Sam was located near latitude 25.6 North, longitude 61.6 West. Sam is moving toward the north-northwest near 16 mph (26 km/h). A turn toward the north with a slight increase in forward speed is anticipated later today, 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. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 150 mph (240 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 day or so, followed by gradual weakening. Sam is forecast to remain a major hurricane into Saturday, with additional weakening forecast 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 175 miles (280 km). The minimum central pressure based on data from the reconnaissance aircraft is 936 mb (27.64 inches).

WIND: Tropical storm conditions are expected on Bermuda beginning tonight 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 later today, 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.
