DISCUSSION AND OUTLOOK ---------------------- At 700 PM CDT (0000 UTC), the center of Tropical Storm Gamma was located by an Air Force Reserve Hurricane Hunter Aircraft near latitude 22.9 North, longitude 87.4 West. The tropical storm is currently drifting east-northeastward near 3 mph (5 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. 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 based on preliminary data from the Hurricane Hunter plane is 998 mb (29.47 inches).

RAINFALL: Gamma is expected to produce an additional 3 to 6 inches of rainfall, with isolated maximum amounts of 8 inches, across portions of the Mexican states of Yucatan, Campeche and Tabasco.

Tropical Storm conditions are possible within the Tropical Storm Watch area later today through Monday. NEXT ADVISORY ------------- Next complete advisory at 1000 PM CDT. $$ Forecaster Zelinsky
