Preparations to protect life and property should have already been completed. 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 700 PM EST (0000 UTC), the eye of Hurricane Iota was located near latitude 13.6 North, longitude 83.0 West. Iota is moving toward the west near 9 mph (15 km/h), and this general motion is forecast through landfall. After landfall, a westward to west-southwestward motion is expected. On the forecast track, the core of Iota will make landfall within the hurricane warning area in northeastern Nicaragua within the next few hours, and dissipate over Central America on Wednesday. Maximum sustained winds are near 160 mph (260 km/h) with higher gusts. Little change in strength is expected until landfall, but rapid weakening is forecast after Iota moves inland. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). Puerto Cabezas airport in Nicaragua recently reported sustained winds of 51 mph (82 km/h) with a gust to 81 mph (130 km/h). The estimated minimum central pressure is 918 mb (27.11 inches) based on Air Force reconnaissance data. 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. STORM SURGE: A life-threatening storm surge will raise water levels by as much as 15 to 20 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. WIND: Catastrophic wind damage is expected where Iota`s eyewall moves onshore within the Hurricane Warning area in Nicaragua tonight with tropical storm conditions already ongoing. Tropical storm conditions are likely on the island of Providencia and San Andres for the next few hours. Tropical storm conditions are occurring in the Tropical Storm Warning area in Nicaragua and will begin in the Tropical Storm Warning area in Honduras later tonight. RAINFALL: Iota is expected to produce the following rainfall accumulations through Thursday: Honduras, northern Nicaragua, southeast Guatemala and southern Belize: 10 to 20 inches (250 to 500 mm). Isolated maximum totals of 30 inches (750 mm) will be possible, especially from northeast Nicaragua into northern Honduras. El Salvador and Panama: 6 to 10 inches (150 to 250 mm), with isolated maximum totals of 15 inches (380 mm). This rainfall would lead to significant, life-threatening flash flooding and river flooding, along with mudslides in areas of higher terrain. Southern Nicaragua and Costa Rica: 3 to 5 inches (75 to 125 mm), with isolated maximum totals of 10 inches (250 mm). 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.
