DISCUSSION AND OUTLOOK
----------------------
At 1000 AM EST (1500 UTC), the center of Hurricane Iota was located
near latitude 13.3 North, longitude 78.5 West. Iota is moving toward
the west-northwest near 9 mph (15 km/h). A westward
to west-northwestward motion is expected during the next day or so
until landfall occurs. After landfall, a westward to
west-southwestward motion is forecast. On the forecast track,
the core of Iota will move across the southwestern Caribbean Sea
today, pass near or just north of Providencia island on
Monday, and approach the coasts of northeastern Nicaragua and
eastern Honduras within the hurricane warning area late Monday.

Maximum sustained winds have increased to near 90 mph (150
km/h) with higher gusts. Rapid strengthening is expected during the
next 36 hours, and Iota is forecast to be an extremely dangerous
category 4 hurricane when it approaches Central America.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 115 miles
(185 km).

The estimated minimum central pressure is 978 mb (28.88 inches).


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.

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

Honduras, northern Nicaragua, Guatemala, southern Belize: 8 to 16
inches (200 to 400 mm). Isolated maximum totals of 20-30 inches (500
to 750 mm) will be possible, especially from northeast Nicaragua
into northern Honduras.

Costa Rica and Panama: 4 to 8 inches (100 to 200 mm), with isolated
maximum totals of 12 inches (300 mm).

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

El Salvador and southern Nicaragua: 3 to 5 inches (75 to 125 mm),
with isolated maximum totals of 10 inches (250 mm).

Northern Colombia: An additional 1 to 3 inches (25 to 75 mm), with
isolated maximum totals near 12 inches (300 mm).

WIND: Potentially catastrophic wind damage is expected where Iota's
eyewall moves onshore within the Hurricane Warning in Nicaragua
and Honduras area beginning late Monday with tropical storm
conditions beginning Monday morning. Hurricane conditions are
expected on the island of Providencia by late tonight with tropical
storm conditions expected beginning this evening. Tropical storm
conditions are expected to begin on the island of San Andres this
evening with hurricane conditions possible there early Monday.
Tropical storm conditions are expected in the Tropical Storm Warning
area in Nicaragua by late Monday and in the warning area in Honduras
by Monday night.

STORM SURGE: A life-threatening storm surge will raise water levels
by as much as 10 to 15 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.

SURF: Swells generated by Iota will affect portions of the coast of
Colombia, and the southern coasts of Hispaniola and Jamaica during
the next day or two. Swells will begin to reach the coasts of
Nicaragua and Honduras tonight and Monday. These swells are
likely to cause life-threatening surf and rip current conditions.
