DISCUSSION AND OUTLOOK ---------------------- At 1000 PM EST (0300 UTC), the center of Tropical Storm Iota was located near latitude 12.7 North, longitude 77.0 West. Iota is moving toward the west near 5 mph (7 km/h). A general westward motion is expected during the next few days. On the forecast track, Iota will move across the southwest Caribbean Sea tonight and Sunday, pass near or over Providencia island on Monday and approach the coasts of Nicaragua and northeastern Honduras Monday evening. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Rapid strengthening is expected during the next day or two, and Iota is forecast to be a major hurricane when it approaches Central America. Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. The estimated minimum central pressure is 990 mb (29.24 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Iota is expected to produce the following rainfall accumulations through Thursday: Honduras, northern Nicaragua, eastern Guatemala, southern Belize: 8 to 16 inches (200 to 400 mm). Isolated maximum totals of 20-30 inches (500 to 750 mm) will be possible, especially from northeast Nicaragua into northern Honduras. Costa Rica, Panama, and northern Colombia: 4 to 8 inches (100 to 200 mm), with isolated maximum totals of 12 inches (300 mm). This rainfall would lead to significant, life-threatening flash flooding and river flooding, along with mudslides in areas of higher terrain. El Salvador, southern Nicaragua and southern Honduras: 2 to 4 inches (50 to 100 mm), with isolated maximum totals of 6 inches (150 mm). Jamaica: 1 to 3 inches (25 to 75 mm). WIND: Hurricane conditions are expected on the island of Providencia by late Sunday night with tropical storm conditions expected beginning Sunday evening. Hurricane conditions are expected within the Hurricane Warning area in Nicaragua and Honduras by late Monday. Tropical storm conditions are expected to begin on the island of San Andres late Sunday or Sunday night with hurricane conditions possible there Sunday night or early Monday. Tropical storm conditions are expected in the Tropical Storm Warning area in Nicaragua by late Monday and in the warning area in Honduras by Monday night. STORM SURGE: A dangerous storm surge will raise water levels by as much as 9 to 13 feet above normal tide levels in areas of onshore winds along the coast of Nicaragua and Honduras. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Iota will affect portions of the coast of Colombia, and the southern coasts of Hispaniola and Jamaica during the next day or two. Swells will begin to reach the coasts of Nicaragua and Honduras on Monday. These swells are likely to cause life-threatening surf and rip current conditions.
