DISCUSSION AND OUTLOOK
———————-
At 1000 PM EST (0300 UTC), the center of Hurricane Iota was located
near latitude 13.6 North, longitude 83.4 West. Iota is moving toward
the west near 9 mph (15 km/h) and this motion is expected to
continue during the next day or so. On the forecast track, Iota
is expected to make landfall in northeastern Nicaragua during the
next hour or two and move inland across northern Nicaragua and
southern Honduras on Tuesday.

Maximum sustained winds are near 155 mph (250 km/h) with higher
gusts. Iota is an extremely dangerous category 4 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Rapid weakening is forecast
after Iota moves inland, and it is expected to dissipate over
Central America on Wednesday.

Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 175 miles
(280 km). Puerto Cabezas airport in Nicaragua recently reported
sustained winds of 70 mph (113 km/h) with a gust to 103 mph
(166 km/h).

The estimated minimum central pressure based on data from an Air
Force reconnaissance aircraft is 920 MB (27.17 inches).

HAZARDS AFFECTING LAND
———————-
STORM SURGE: A life-threatening storm surge will raise water levels
by as much as 15 to 20 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: Catastrophic wind damage is occurring near Iota’s eyewall and
these winds will spread inland across northern Nicaragua during the
next several hours. Tropical storm conditions are occurring in the
Tropical Storm Warning areas in Nicaragua and Honduras. Tropical
storm conditions should subside during the next few hours on the
islands of Providencia and San Andres.

RAINFALL: Iota is expected to produce the following rainfall
accumulations through Thursday:

Honduras, northern Nicaragua, southeast Guatemala and southern
Belize: 10 to 20 inches (250 to 500 mm). Isolated maximum totals of
30 inches (750 mm) across northeast Nicaragua and northern Honduras.

El Salvador and Panama: 6 to 10 inches (150 to 250 mm), with
isolated maximum totals of 15 inches (380 mm).

This rainfall would 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).

This rainfall would 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.
