DISCUSSION AND OUTLOOK
----------------------
At 700 PM EST (0000 UTC), the eye of Hurricane Eta was located near
along the coast of Nicaragua near latitude 13.8 North, longitude
83.7 West. Eta is moving toward the west near 5 mph (7 km/h) A
faster westward or west-northwestward motion is expected through
early Thursday.  A turn toward the north, and then north-northeast
is forecast Thursday night and Friday. On the forecast track, the
center of Eta is expected to move inland over northern Nicaragua
through Wednesday morning, and then move across the central portions
of Honduras through Thursday morning.  The system is forecast to
emerge over the northwestern Caribbean Sea Thursday night or Friday.

Maximum sustained winds have decreased to near 110 mph (175 km/h)
with higher gusts.  Eta is now a strong category 2 hurricane on the
Saffir-Simpson Hurricane Wind Scale.  Rapid weakening will continue
as the center moves farther inland tonight and Wednesday.

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). During the past couple of hours, a sustained wind of
107 mph (172 km/h) and a gust to 135 (217 km/h) were measured at the
Puerto Cabezas, Nicaragua, airport.

The estimated minimum central pressure is 965 mb (28.50 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Eta can be found in the Tropical Cyclone Discussion
under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC.

WIND:  Catastrophic wind damage is expected where Eta's eyewall
tracks within the Hurricane Warning area.  Tropical storm
conditions are expected in the Tropical Storm Warning area through
tonight.

RAINFALL:  Eta is expected to produce the following rainfall amounts
through Sunday morning:

Much of Nicaragua and Honduras: 15 to 25 inches (380 to 635 mm),
isolated amounts of 35 inches (890 mm).

Eastern Guatemala and Belize: 10 to 20 inches (255 to 510 mm),
isolated amounts of 25 inches (635 mm).

Portions of Panama and Costa Rica: 10 to 15 inches (255 to 380 mm),
isolated amounts of 25 inches (635 mm).

El Salvador and southeast Mexico: 5 to 10 inches (125 to 255 mm),
isolated amounts of 15 inches (380 mm)

Jamaica, Southern Haiti, the Cayman Islands: An additional 3 to 5
inches (75 to 125 mm), isolated storm totals of 15 inches (380 mm).

This rainfall will lead to catastrophic, life-threatening flash
flooding and river flooding, along with landslides in areas of
higher terrain of Central America.  Flash flooding and river
flooding will be possible across Jamaica, southeast Mexico, El
Salvador, southern Haiti, and the Cayman Islands.

STORM SURGE:  A dangerous 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 within the hurricane warning
area, and 3 to 5 feet above normal tide levels along the coast of
Honduras within the tropical storm warning area.  Near the coast,
the surge will be accompanied by large and destructive waves.

SURF:  Swells generated by Eta are expected to affect portions of
the coast of Central America and the Yucatan Peninsula of Mexico
during the next few days.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
