DISCUSSION AND OUTLOOK ---------------------- Satellite imagery and ship and buoy data indicate that the circulation of the low pressure system has become better defined, and the disturbance is now Tropical Storm Nestor. At 100 PM CDT (1800 UTC), the center of Tropical Storm Nestor was located near latitude 26.3 North, longitude 89.5 West. Nestor is moving toward the northeast near 22 mph (35 km/h), and this general motion is expected to continue through Sunday, followed by a turn toward the east-northeast by early Monday. On the forecast track, the center of Nestor will approach the northern Gulf Coast later today and tonight and move inland across portions of the southeastern United States Saturday and Sunday as it becomes a post-tropical cyclone. Nestor is expected to move offshore of the coast of North Carolina into the western Atlantic by late Sunday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Some strengthening is expected later today, with weakening forecast after Nestor moves inland. Nestor is expected to lose tropical characteristics and become post-tropical on Saturday. Tropical-storm-force winds extend outward up to 175 miles (280 km), mainly to the northeast and east of the center. The estimated minimum central pressure is 1001 mb (29.56 inches). HAZARDS AFFECTING LAND ---------------------- STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Indian Pass FL to Chassahowitzka FL...3 to 5 ft Chassahowitzka to Clearwater Beach FL...2 to 4 ft Tampa Bay...1 to 3 ft Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. WIND: Tropical storm conditions are expected to reach the coast within the warning area by later today and this evening, making outside preparations difficult or dangerous. Gale-force winds are likely along portions of the Atlantic coast of the southeastern United States by Saturday. RAINFALL: Nestor is expected to produce total rainfall accumulations of 2 to 4 inches this weekend from the central Gulf Coast and northern and central Florida to the eastern Carolinas, with isolated maximum amounts of 6 inches. TORNADOES: A tornado or two is possible tonight and early Saturday near the Florida Gulf Coast from the central panhandle to western parts of the Florida peninsula.
