WIND:  Strong winds are occuring near the center of Iota and
these winds will spread farther inland across southern Honduras
during the next several hours.  Tropical storm conditions are also
occurring in the Tropical Storm Warning areas along the coast in
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.
