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).
