DISCUSSION AND OUTLOOK
----------------------
At 900 AM CST (1500 UTC), the center of Tropical Storm Eta was
located near latitude 13.9 North, longitude 85.2 West. Eta is moving
toward the west near 7 mph (11 km/h).  A west-northwestward motion
at a faster forward speed is expected later today through Thursday
morning.  A turn toward the north, and then northeast is forecast
Thursday night and Friday.  On the forecast track, the center of Eta
is expected to move over northern Nicaragua through early this
afternoon, and then move across the central portions of Honduras
through Thursday morning. The system is forecast to emerge over the
Gulf of Honduras or the northwestern Caribbean Sea Thursday night
and Friday.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
Continued weakening will occur while Eta moves over land during the
next couple of days, and Eta should become a tropical depression
tonight.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
mainly to the east of the center.

The estimated minimum central pressure is 996 mb (29.42 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Eta can be found in the Tropical Cyclone Discussion
under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC, and on the
web at www.hurricanes.gov/text/MIATCDAT4.shtml.

WIND:  Tropical storm conditions are expected in the warning area
for a few more hours, and near the center of Eta for several more
hours.

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

Much of Nicaragua and Honduras: An additional 10 to 20 inches
(255 to 510 mm), isolated maximum totals of 40 inches (1000 mm) in
northeast Nicaragua and eastern Honduras..

Eastern Guatemala and Belize: 15 to 25 inches (380 to 635 mm),
isolated amounts of 30 inches (760 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)

The Cayman Islands:  An additional 5 to 15 inches (125 to 380 mm),
isolated storm totals of 20 inches (510 mm).

Jamaica and Southern Haiti: 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:  Water levels along the coasts of Nicaragua and
Honduras should gradually decrease today.

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.
