DISCUSSION AND OUTLOOK
----------------------
At 300 PM CST (2100 UTC), the center of Tropical Depression Eta was
located near latitude 17.3 North, longitude 86.5 West. The
depression is moving toward the northeast near 7 mph (11 km/h). A northeastward motion at a faster forward speed is expected trough
early Sunday. On the forecast track, the center of Eta will move
across the northwestern Caribbean Sea tonight and Friday, approach
the Cayman Islands Saturday, and be near central or western Cuba
Saturday night and Sunday.

Reports from an Air Force Reserve Hurricane Hunter aircraft
indicate that maximum sustained winds are near 35 mph (55 km/h)
with higher gusts. Eta is forecast to become a tropical storm
again this tonight, with further strengthening likely through
early Sunday.

The estimated minimum central pressure from the Hurricane Hunter
aircraft data is 1002 mb (29.59 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 Wednesday morning:

Portions of Central America: An additional 2 to 5 inches (50 to 125
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 threat of life-threatening flooding will continue across
portions of Central America, along with landslides in areas of
higher terrain. Significant, life-threatening flash flooding and
river flooding is possible in the Cayman Islands and Cuba. Flash
flooding and urban flooding is also possible for Jamaica, southeast
Mexico, the Bahamas and Southern Florida.

STORM SURGE: A dangerous storm surge will raise water levels by as
much as 2 to 4 feet above normal tide levels along the coast of
Cuba near and to the east of where the center makes landfall. Near
the coast, the surge will be accompanied by large and destructive
waves.

WIND: Tropical storm conditions are expected in the Cayman Islands
late Saturday and Saturday night. Tropical storm conditions are
expected in the warning area in Cuba Saturday night and Sunday, and
they 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.
