A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. Interests elsewhere in Nicaragua and Honduras should monitor the progress of Iota. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 100 AM EST (0600 UTC), the center of Hurricane Iota was located by an Air Force Reserve reconnaissance aircraft near latitude 13.5 North, longitude 80.7 West. Iota is moving toward the west near 10 mph (17 km/h). A westward to west-northwestward motion is expected through landfall. After landfall, a westward to west-southwestward motion is forecast. On the forecast track, the core of Iota will pass near or over Providencia island during the next few hours, and make landfall within the hurricane warning area in northeastern Nicaragua and eastern Honduras tonight. Reports from the aircraft indicate that maximum sustained winds have increased to near 125 mph (205 km/h) with higher gusts. Iota is now a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Rapid strengthening is expected during the next 24 hours, and Iota is forecast to be an extremely dangerous category 4 hurricane when it approaches Central America tonight. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 150 miles (240 km). The latest data from the reconnaissance aircraft indicate that the minimum central pressure is 945 mb (27.91 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Hurricane Iota can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1, WMO header WTNT41 KNHC and on the web at www.hurricanes.gov/text/MIATCDAT1.shtml. RAINFALL: Iota is expected to produce the following rainfall accumulations through Friday morning: Honduras, northern Nicaragua, 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 and Panama: 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 and southern Nicaragua: 3 to 5 inches (75 to 125 mm), with isolated maximum totals of 10 inches (250 mm). Northern Colombia: An additional 1 to 3 inches (25 to 75 mm), with isolated maximum totals near 12 inches (300 mm). WIND: Potentially catastrophic wind damage is expected where Iota's eyewall moves onshore within the Hurricane Warning area in Nicaragua and Honduras beginning late tonight with tropical storm conditions expected this morning. Hurricane conditions are expected on the island of Providencia shortly with tropical storm conditions expected to continue through this morning and possibly into the early afternoon. Tropical storm conditions are expected to begin on the island of San Andres shortly with hurricane conditions possible there later this morning. Tropical storm conditions are expected in the Tropical Storm Warning area in Nicaragua by late afternoon and in the warning area in Honduras by tonight. STORM SURGE: A life-threatening storm surge will raise water levels by as much as 10 to 15 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 much of the coast of Central America, the Yucatan Peninsula, Jamaica, and Colombia during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
