DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 AM AST (0900 UTC), the center of Hurricane Joaquin was located near latitude 40.5 North, longitude 49.4 West. Joaquin is moving toward the east-northeast near 32 mph (52 km/h) and this motion is expected to continue through Friday. Maximum sustained winds have decreased to near 75 mph (120 km/h) with higher gusts, and additional weakening is forecast during the next 48 hours. Joaquin is expected to lose tropical characteristics by tomorrow evening, and to become a large extratropical cyclone by Thursday. Hurricane force winds extend outward up to 60 miles (95 km) from the center and tropical storm force winds extend outward up to 275 miles (445 km). The estimated minimum central pressure is 977 mb (28.85 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Joaquin will continue to affect Bermuda and Atlantic Canada during the next day or so. Swells affecting much of the eastern coast of the United States are now mostly associated with a non-tropical area of low pressure over the Western Atlantic, and these swells are expected to continue for the next day or two. Life-threatening surf and rip current conditions are likely in association with these swells. Please consult products from your local weather office.
