DISCUSSION AND OUTLOOK
----------------------
At 100 PM CDT (1800 UTC), the center of Tropical Storm Zeta was 
located by an Air Force Reserve Hurricane Hunter aircraft near 
latitude 19.3 North, longitude 85.6 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 minimum central pressure estimated from Hurricane Hunter
aircraft observations is 986 mb (29.12 inches).
