DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Tropical Storm Zeta was located near latitude 18.1 North, longitude 83.8 West. Zeta is drifting toward the north-northwest near 2 mph (4 km/h) but a faster northwestward motion is expected over the next couple of days, followed by a turn to the north. On the forecast track, the center of Zeta will move near or over the northern Yucatan Peninsula or the Yucatan Channel late Monday, move over the southern Gulf of Mexico on Tuesday, and approach the northern Gulf Coast on Wednesday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Strengthening is forecast, and Zeta is expected to become a hurricane before it moves near or over the Yucatan Peninsula late Monday. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 997 mb (29.44 inches).

Additional rainfall amounts of 1 to 2 inches with local amounts of 4 inches possible across Southern Florida and the Keys through Tuesday, with isolated storm total accumulations of 8 inches. Between Wednesday and Friday, storm total rainfall of 2 to 4 inches, with local 6 inch amounts, is expected across sections of the U.S. Gulf Coast and the southern U.S. near and in advance of Zeta. Heavy rainfall will spread north into the Tennessee Valley, Southern Appalachians, and portions of the Mid-Atlantic States near and in advance of Zeta late in the week. The expected rainfall could lead to flash flooding and minor river flooding.

STORM SURGE: A dangerous storm surge will raise water levels by as much as 1-3 feet above normal tide levels along the immediate coast in the Hurricane Warning area near and to the north of where the center makes landfall in the Yucatan Peninsula.
