For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 200 AM EDT (0600 UTC), the center of Subtropical Storm Ana was located near latitude 32.2 North, longitude 77.5 West. The storm is moving toward the north-northwest near 3 mph (6 km/h). A turn toward the northwest and then back to the north at a slightly faster forward speed is expected over the next 48 hours. On the forecast track, the center will be near the coasts of South and North Carolina by Sunday morning. Data from NOAA Doppler weather radars indicate that maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Little additional strengthening is forecast through today. A gradual weakening trend is likely to begin within 24 hours. Winds of 40 mph extend outward up to 140 miles (220 km) from the center. During the past hour, the Frying Pan Shoals NOAA buoy measured a sustained wind of 37 mph (57 km/h) and a gust to 47 mph (76 km/h). The estimated minimum central pressure was 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected within the warning area, and possible within the watch area, by this afternoon or evening. STORM SURGE: The combination of storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters. The water could reach 1 to 2 ft above ground at times of high tide in coastal areas from Cape Hatteras, North Carolina southward through South Carolina. For information specific to your area, please see products issued by your local National Weather Service forecast office. RAINFALL: Ana is expected to produce rainfall accumulations of 2 to 4 inches, with isolated amounts of 6 inches, over eastern portions of North Carolina and South Carolina through the weekend. SURF: Swells generated by Ana are affecting portions of the southeastern U.S. coast. These swells will likely cause life- threatening surf and rip currents. Please see statements issued by your local National Weather Service forecast office. NEXT ADVISORY ------------- Next complete advisory at 500 AM EDT. $$ Forecaster Stewart/Roberts
