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 1200 PM CST (1800 UTC), the center of Tropical Storm Iota was located near latitude 13.7 North, longitude 85.7 West. Iota is moving toward the west near 12 mph (19 km/h). The storm will move farther inland across northern Nicaragua today, and move across southern Honduras tonight before dissipating near El Salvador early Wednesday. Maximum sustained winds have decreased to near 65 mph (105 km/h) with higher gusts. Iota should weaken to a tropical depression this evening, and degenerate into a remnant low pressure area on Wednesday. Tropical-storm-force winds extend outward up to 175 miles (280 km). The estimated minimum central pressure is 988 mb (29.18 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for 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. WIND: Strong winds are occuring near the center of Iota and these winds will spread farther inland across northern Nicaragua and southern Honduras during the next several hours. Tropical storm conditions are also occurring in the Tropical Storm Warning areas along the coast in Nicaragua and Honduras. RAINFALL: Iota is expected to produce the following rainfall accumulations through Thursday: Honduras, northern Nicaragua, southeast and central Guatemala and southern Belize: 10 to 20 inches (250 to 500 mm), with isolated maximum totals of 30 inches (750 mm). El Salvador and Panama: 4 to 8 inches (100 to 200 mm), with isolated maximum totals of 12 inches (300 mm). This rainfall will 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 and the Yucatan Peninsula during the next day or so. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 300 PM CST. $$ Forecaster Blake

Hurricane Iota Forecast Discussion Number 17

2020-11-17 15:41:27| National Hurricane Center (Atlantic)

Issued at 900 AM CST Tue Nov 17 2020 000 WTNT41 KNHC 171441 TCDAT1 Hurricane Iota Discussion Number 17 NWS National Hurricane Center Miami FL AL312020 900 AM CST Tue Nov 17 2020 Satellite images indicate that Iota continues to weaken over land with warming cloud tops near the center. It still has a small core, however, so the initial wind speed will be lowered to 65 kt on this advisory, in line with the Decay-SHIPS model. Further weakening is expected today as Iota moves westward at about 10 kt, with Iota becoming a tropical storm this afternoon, and a tropical depression tonight. Iota should degenerate into a remnant low near El Salvador by tomorrow due to the rugged terrain of central America. While the winds of Iota are weakening, there are still life- threatening hazards ongoing for central America, including flash flooding and mud slides, which could result in potentially catastrophic effects, especially when compounded upon Hurricane Eta's destruction from a couple of weeks ago. Key Messages: 1. Life-threatening flash flooding and river flooding is expected through Thursday across portions of Central America due to heavy rainfall from Iota. Flooding and mudslides across portions of Honduras, Nicaragua and Guatemala could be exacerbated by Hurricane Etas recent effects there, resulting in significant to potentially catastrophic impacts. 2. Strong winds, primarily close to the center of Iota and along the coasts of Nicaragua and Honduras, are still expected for the next several hours.
