DISCUSSION AND OUTLOOK
At 1000 PM CDT (0300 UTC), data from an Air Force Reserve Hurricane
Hunter aircraft indicated that the center of Tropical Storm Gamma
was located near latitude 22.8 North, longitude 87.2 West. The
tropical storm is drifting toward the east near 2 mph (4 km/h).
Gamma is forecast to gradually turn toward the southwest or
west-southwest on Monday and move slowly in that direction through
mid-week. On the forecast track, the center of Gamma will continue
to meander offshore of the northern Yucatan Peninsula tonight 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.
Some weakening is forecast during the next 48 hours. Gradual
weakening is anticipated to begin 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 based on measurements from
the hurricane hunter plane is 998 mb (29.47 inches).
