DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 800 PM EDT (0000 UTC), the center of Subtropical Storm Ana was located near latitude 31.9 North, longitude 77.3 West. The storm continues to meander, 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 are near 45 mph (75 km/h), with higher gusts. Ana is expected to make the transition to a tropical storm by early Saturday. Little change in strength is expected over the next day or so, but some weakening is forecast to begin when the center nears the coastline. Winds of 40 mph extend outward up to 115 miles (185 km) from the center. The minimum central pressure estimated from Air Force Reserve Unit Hurricane Hunter aircraft data is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected within the warning area, and possible within the watch area, 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 complete advisory at 1100 PM EDT. $$ Forecaster Pasch
