DISCUSSION AND OUTLOOK ---------------------- At 500 AM EDT (0900 UTC), the center of Tropical Storm Zeta was located by a NOAA Hurricane Hunter aircraft near latitude 18.7 North, longitude 84.3 West. Zeta is moving toward the northwest near 9 mph (15 km/h). A northwestward motion with an increase in forward speed is expected over the day or so, followed by a turn toward the north Tuesday night. A faster northward to north-northeastward motion is forecast on Wednesday. On the forecast track, the center of Zeta will move near or over the northern Yucatan Peninsula later today or tonight, move over the southern Gulf of Mexico on Tuesday, and approach the northern Gulf Coast on Wednesday. Data from a NOAA Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 70 mph (110 km/h) with higher gusts. Strengthening is forecast, and Zeta is expected to become a hurricane later this morning. Additional strengthening is expected before Zeta moves over the Yucatan Peninsula. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The latest minimum central pressure estimated from NOAA reconnaissance aircraft data is 990 mb (29.24 inches).

RAINFALL: Rainfall totals of 4 to 8 inches with local amounts of 12 inches are possible through Tuesday along and east-northeast of Zeta’s track across the Yucatan Peninsula of Mexico, the Cayman Islands, and central to western Cuba. Between Tuesday night and Thursday, storm total rainfall of 2 to 4 inches with isolated amounts of 6 inches is expected across portions of the central U.S. Gulf Coast, Tennessee Valley, southern Appalachians, and Mid-Atlantic States near and in advance of Zeta. The expected rainfall could lead to flash, urban, and small stream flooding, along with minor river flooding.

Tropical storm conditions are expected within the Tropical Storm Warning area in Mexico by late today. Tropical storm conditions could occur in the warning area in western Cuba beginning later today.
