At 400 AM EST (0900 UTC), the center of Hurricane Iota was located 
near latitude 13.7 North, longitude 84.3 West. Iota is moving toward 
the west near 9 mph (15 km/h), and this general motion is expected 
to continue during the next day or so.  On the forecast track, Iota 
will move farther inland across northern Nicaragua today, and move 
across southern Honduras tonight and Wednesday.
 
Maximum sustained winds are near 105 mph (165 km/h) with higher
gusts.  Iota is now a category 2 hurricane on the Saffir-Simpson 
Hurricane Wind Scale.  Additional rapid weakening is expected today
into Wednesday, and Iota is forecast to dissipate over Central 
America by Wednesday night.
 
Hurricane-force winds extend outward up to 35 miles (55 km) from 
the center and tropical-storm-force winds extend outward up to 
175 miles (280 km).  Puerto Cabezas airport in Nicaragua recently 
reported a sustained wind of 51 mph (82 km/h) and a gust to 77 mph

HAZARDS AFFECTING LAND
----------------------
Key messages for Hurricane 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.
 
STORM SURGE:  A life-threatening storm surge will raise water levels
by as much as 5 to 10 feet above normal tide levels in areas of
onshore winds along the coast of Nicaragua and Honduras.  Near the
coast, the surge will be accompanied by large and destructive waves.
 
WIND:  Significant wind damage is occurring near Iota's eyewall 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.
 
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 couple of
days. These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.
