DISCUSSION AND OUTLOOK
----------------------
At 1200 AM CST (0600 UTC), the center of Tropical Depression Eta was
located near latitude 17.0 North, longitude 87.6 West. The
depression is moving toward the north near 8 mph (13 km/h). A turn
toward the northeast is expected later today, with this motion
continuing through early Sunday.  On the forecast track, the center
of Eta will move across the northwestern Caribbean Sea today,
approach the Cayman Islands Saturday, and be near Cuba Saturday
night and Sunday.

Maximum sustained winds are near 35 mph (55 km/h) with higher
gusts. Eta is forecast to become a tropical storm again later today,
with further strengthening likely through early Sunday.

The estimated minimum central pressure based on nearby surface
observations is 1004 mb (29.65 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.

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

Portions of Central America: An additional 5 to 10 inches (125 to
255 mm), isolated maximum storm totals of 40 inches (1000 mm) in
eastern Honduras and eastern Nicaragua.

Southeastern Mexico and Jamaica: An additional 2 to 5 inches (50 to
125 mm), isolated maximum storm totals of 15 inches (380 mm).

The Cayman Islands into portions of Cuba: 10 to 20 inches (255 to
510 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.  Significant, life-threatening
flash flooding and river flooding is possible in the Cayman Islands
and Cuba.  Flash flooding and river flooding is expected for Jamaica
and southeast Mexico.

WIND: Tropical storm conditions are possible in the Cayman Islands
Saturday or Saturday night.

SURF:  Swells generated by Eta are expected to spread northeastward
and affect the Cayman Islands, Jamaica, and the southern coast of
Cuba 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.
