DISCUSSION AND OUTLOOK
At 1000 AM CDT (1500 UTC), the center of Tropical Storm Zeta was
located near latitude 19.1 North, longitude 85.3 West. Zeta is
moving toward the northwest near 10 mph (17 km/h). A northwestward
motion with some increase in forward speed is expected over the
next 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.
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Strengthening is forecast, and Zeta is expected to become
a hurricane later today. Some weakening is likely while Zeta
moves over the Yucatan Peninsula tonight and early Tuesday. Zeta
is forecast to strengthen again while it moves over the southern
Gulf of Mexico later on Tuesday
Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center.
The estimated minimum central pressure is 992 mb (29.29 inches).
