Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Some strengthening is forecast during the next 48 hours, and Zeta could become a hurricane by the time it moves near or over the Yucatan Peninsula late Monday. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The estimated minimum central pressure is 1005 mb (29.68 inches).
