On the forecast track, Iota will move across the central Caribbean Sea during the next day or so, and approach the coasts of Nicaragua and northeastern Honduras on Monday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Steady to rapid strengthening is likely over the weekend, and Iota is forecast to be a major hurricane when it approaches Central America. Tropical-storm-force winds extend outward up to 90 miles (150 km) to the northeast of the center. The estimated minimum central pressure is 1005 mb (29.68 inches).
