Maximum sustained winds have decreased to near 40 mph (65 km/h) with higher gusts. Additional rapid weakening is forecast, and Iota should weaken to a tropical depression tonight and degenerate into a remnant low pressure area on Wednesday. Tropical-storm-force winds extend outward up to 185 miles (295 km) from the center, mainly along the coast in the Tropical Storm Warning area. La Ceiba, Honduras, reported a wind gust of 58 mph (93 km/h) during the past few hours. The estimated minimum central pressure is 1000 mb (29.53 inches).
