DISCUSSION AND OUTLOOK

At 900 AM CST (1500 UTC), the center of Tropical Depression Eta was
located near latitude 17.8 North, longitude 87.0 West. The
depression is moving toward the north-northeast near 7 mph       
(11 km/h).  A turn toward the northeast and a faster forward speed 
are 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 central or western 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 is 1004 mb (29.65 inches).

(380 mm).

This rainfall will continue 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

the Bahamas and Southern Florida.

WIND: Tropical storm conditions are expected in the Cayman Islands
late Saturday and Saturday night.  Tropical storm conditions are 
possible in the watch area in Cuba Saturday night and Sunday.

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.
