Preparations to protect life and property should be rushed to completion. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous.

A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 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 400 PM EST (2100 UTC), the center of Tropical Storm Iota was located near latitude 12.6 North, longitude 76.5 West. Iota is moving toward the west-southwest near 7 mph (11 km/h). A westward motion with some increase in forward speed is expected to begin very soon and continue through Monday night. 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 afternoon or evening. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that the maximum sustained winds have increased to near 60 mph (95 km/h) with higher gusts. Steady to rapid strengthening is expected during the next day or two, and Iota is forecast to be at or near major hurricane strength 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 based on Air Force Reserve reconnaissance aircraft data is 995 mb (29.39 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 possible within the Hurricane Warning area in Nicaragua and Honduras by late Monday, with tropical storm conditions possible by Monday afternoon. Tropical storm conditions are expected to begin on the island of San Andres late Sunday or Sunday night with hurricane conditions possible Sunday night or early Monday. 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. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 700 PM EST. Next complete advisory at 1000 PM EST. $$ Forecaster Brown |
