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.

RAINFALL: The remnants of Iota are expected to produce the following additional rainfall accumulations through Thursday:

Portions of Honduras, Guatemala, southern Belize: 4 to 8 inches (100 to 200 mm), with isolated maximum totals of 12 inches (300 mm).

Portions of Nicaragua and El Salvador: 2 to 4 inches (50 to 100 mm), with isolated maximum totals of 6 inches (150 mm).

This rainfall will lead to significant, life-threatening flash flooding and river flooding, along with mudslides in areas of higher terrain.

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.
