DISCUSSION AND OUTLOOK
At 700 PM EST (0000 UTC), the eye of Hurricane Iota was located near
latitude 13.6 North, longitude 83.0 West. Iota is moving toward the
west near 9 mph (15 km/h), and this general motion is forecast
through landfall. After landfall, a westward to west-southwestward
motion is expected. On the forecast track, the core of Iota will
make landfall within the hurricane warning area in northeastern
Nicaragua within the next few hours, and dissipate over Central
America on Wednesday.
Maximum sustained winds are near 160 mph (260 km/h) with higher
gusts. Little change in strength is expected until landfall, but
rapid weakening is forecast after Iota moves inland.
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 51 mph (82 km/h) with a gust to 81 mph
The estimated minimum central pressure is 918 mb (27.11 inches)
based on Air Force reconnaissance data.
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 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 expected where Iota's eyewall
moves onshore within the Hurricane Warning area in Nicaragua tonight
with tropical storm conditions already ongoing. Tropical storm
conditions are likely on the island of Providencia and San Andres
for the next few hours. Tropical storm conditions are occurring in
the Tropical Storm Warning area in Nicaragua and will begin in the
Tropical Storm Warning area in Honduras later tonight.
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) will be possible, especially from northeast
Nicaragua into 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
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, the Yucatan Peninsula, Jamaica, and Colombia 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.
