WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.

The governments of Nicaragua and Honduras continue to issue
warnings on heavy rain and flooding in those countries, and
interests in Nicaragua and Honduras should continue to monitor the
progress of this system.  Interests in Belize, western Cuba, and
the Cayman Islands should also monitor the progress of this system.

DISCUSSION AND OUTLOOK
----------------------
At 600 PM CST (0000 UTC), the center of Tropical Storm Eta was
located near latitude 14.1 North, longitude 86.1 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 tonight through Thursday
morning.  A turn toward the north, and then the northeast is
forecast Thursday night and Friday.  On the forecast track, the
center of Eta is expected to move across Honduras through Thursday
afternoon, and emerge over the Gulf of Honduras by Thursday night.
Eta is forecast to approach the Cayman Islands and western Cuba this
weekend.

Maximum sustained winds are now near 35 mph (55 km/h) with higher
gusts.  Additional weakening is expected while Eta remains over land
during the next day or so, and Eta could degenerate to a remnant low
during that time.  However, re-intensification is forecast once the
center of Eta moves over the Caribbean Sea.

The estimated minimum central pressure is 1002 mb (29.59 inches).


HAZARDS AFFECTING LAND

Portions of Honduras, Guatemala and Belize: An additional 15 to 30
inches (380 to 760 mm), isolated maximum storm totals of 40 inches
(1000 mm) in eastern Honduras.

Portions of Nicaragua, El Salvador and Costa Rica: An additional 15
to 20 inches (380 to 510 mm), isolated maximum storm totals of 40
inches (1000 mm) in eastern Nicaragua.

Southeastern Mexico: 5 to 15 inches (125 to 380 mm), isolated
maximum totals of 20 inches (510 mm).

Jamaica: An additional 3 to 5 inches (75 to 125 mm), isolated
maximum storm totals totals of 15 inches (380 mm).

The Cayman Islands into western Cuba: 10 to 25 inches (255 to 635
mm), isolated maximum totals of 30 inches (760 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, southern
Haiti, the Cayman Islands and western Cuba.

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 couple of days.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
