Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Weakening is forecast to begin later this afternoon or evening, and Ileana is likely to degenerate into a remnant low tonight. The remnant low is expected to dissipate by Monday. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The Mexican Navy station at Topolobampo recently reported sustained winds of 31 mph (50 km/h) and a wind gust of 40 mph (65 km/h). The estimated minimum central pressure is 1002 mb (29.59 inches).
