Hurricane Iota

17 Nov 2020 / Nicaragua

At 900am CST (1500 UTC), the center of Hurricane Iota was near latitude 13.7 North, longitude 85.2 West and moving toward the west near 12 mph (19 km/h). The hurricane will move farther inland across northern Nicaragua today (17 November), and move across southern Honduras tonight before dissipating near El Salvador early Wednesday.

Maximum sustained winds have decreased to near 75 mph (120 km/h) with higher gusts. Iota should weaken to a tropical storm this afternoon, a tropical depression this evening, and degenerate into a remnant low pressure area on Wednesday.

Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km)…

…Strong winds are occuring near the center of Iota and these winds will spread farther inland across northern Nicaragua during the next several hours. Tropical storm conditions are occurring in the Tropical Storm Warning areas in Nicaragua and Honduras.

Iota is expected to produce the following rainfall accumulations through Thursday:
- Honduras, northern Nicaragua, southeast & central Guatemala and southern Belize: 10-20 inches (250-500 mm), with isolated maximum totals of 30 inches (750 mm).
- El Salvador and Panama: 4-8 inches (100-200 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: 3-5 inches (75-125 mm), with isolated maximum totals of 10 inches (250 mm).

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…
