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 500 PM EDT (2100 UTC), the center of Subtropical Storm Ana was located near latitude 31.7 North, longitude 77.4 West. The storm has been meandering today, but is expected to begin a north- northwestward motion overnight. A turn toward the northwest with a slight increase in forward speed is expected on Saturday. On the forecast track the center of Ana will be close to the coasts of South and North Carolina on Sunday. Maximum sustained winds remain near 45 mph (75 km/h), with higher gusts. Satellite images indicate that Ana continues its transition to a tropical storm, which should be complete by early Saturday. Little change in strength is expected while the storm approaches the coastline over the next couple of days. Winds of 40 mph extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 1001 mb (29.56 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected within the warning area, and possible within the watch areas, by Saturday 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 intermediate advisory at 800 PM EDT. Next complete advisory at 1100 PM EDT. $$ Forecaster Blake |
