DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the center of Tropical Storm Gamma was
located near latitude 22.4 North, longitude 87.8 West and has
stalled just north of the northern coast of the Yucatan Peninsula.  
Gamma should slowly turn toward the west-southwest tonight or 
Monday, and a west-southwestward drift should continue Monday night 
through early Wednesday.  On the forecast track, the center of 
Gamma will meander offshore of the northern Yucatan Peninsula and 
over the extreme southern Gulf of Mexico today, and pass near or 
just offshore of the northern coast of the Yucatan Peninsula on 
Monday and Tuesday. 
 
Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
Gradual weakening is anticipated to begin later tonight or on Monday
and continue into Tuesday.  Afterward, little change in strength is 
forecast.

Tropical-storm-force winds extend outward up to 160 miles (260 km)
from the center.
 
The estimated minimum central pressure is 997 mb (29.44 inches).
