DISCUSSION AND OUTLOOK ---------------------- At 800 AM EDT (1200 UTC), the center of Tropical Storm Zeta was located near latitude 35.3 North, longitude 83.5 West. Zeta is racing toward the northeast near 39 mph (63 km/h). An even faster northeastward motion is expected later today, followed by a rapid east-northeastward motion tonight and Friday. On the forecast track, the center of Zeta will move across portions of the southeastern U.S. this morning, across the Mid-Atlantic states this afternoon, and emerge over the western Atlantic by tonight. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Zeta is expected to become a non-tropical gale-force low later today. The low should become absorbed by a frontal system over the western Atlantic by Friday night. Tropical-storm-force winds extend outward up to 175 miles (280 km) from the center. A sustained wind of 41 mph (67 km/h) and a gust to 82 mph (131 km/h) was recently reported at Cashiers, North Carolina. The estimated minimum central pressure based on surface observations is 990 mb (29.18 inches).

STORM SURGE: Water levels along the Central Gulf coast will gradually subside throughout the day. Consult products issued by your local National Weather Service forecast office for additional information. WIND: Damaging winds, especially in gusts, are spreading across northern Georgia, western South Carolina, and western North Carolina. These winds will shift into other portions of North Carolina and southeastern Virginia later today. Wind gusts could be especially severe across the southern Appalachian Mountains. RAINFALL: Areas of heavy rainfall, both in advance of Zeta and along the track of Zeta, will impact areas from the central Appalachians, Mid-Atlantic and lower to middle Ohio Valley through Thursday. Rainfall totals of 1 to 3 inches are expected across these areas, resulting in possible flash, urban, small stream, and isolated minor river flooding.
