DISCUSSION AND OUTLOOK ---------------------- At 400 AM CDT (0900 UTC), the center of Tropical Storm Zeta was located near latitude 34.0 North, longitude 85.5 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. The estimated minimum central pressure based on surface observations is 988 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: Tropical storm conditions are expected to continue within the warning area near the northern Gulf Coast for a few more hours. Damaging winds, especially in gusts, are spreading well inland across portions of central and northern Alabama, and northern Georgia, and these winds will shift into eastern Tennessee, the Carolinas, 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. TORNADOES: A few tornadoes could occur this morning from parts of the Florida Panhandle across southeastern Alabama and Georgia. A tornado or two is possible later today over the Carolinas and southern Virginia. NEXT ADVISORY ------------- Next intermediate advisory at 700 AM CDT.
