DISCUSSION AND OUTLOOK
----------------------
At 1000 AM EST (1500 UTC), the center of Tropical Storm Eta was
located near latitude 14.8 North, longitude 77.2 West. Eta is moving
toward the west near 15 mph (24 km/h), and this motion with
some decrease in forward speed is expected to continue through
tonight.  A slower motion toward the west-southwest is forecast on
Monday and Tuesday.  On the forecast track, the center of the
cyclone is expected to be near the northeastern coasts of Nicaragua
and Honduras by Tuesday morning.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Strengthening is forecast during the next couple of days, and Eta is
expected to become a hurricane by late Monday.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center.

The estimated minimum central pressure is 1005 mb (29.68 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected in the Hurricane Warning
area by early Tuesday, with tropical storm conditions possible in
this area by late Monday. Tropical storm conditions are expected in
the Tropical Storm Warning area by late Monday, and hurricane
conditions are possible in the Hurricane Watch area by early
Tuesday.

RAINFALL:  Eta is expected to produce the following rainfall amounts
through Thursday evening:

Central and northern Nicaragua into much of Honduras: 15 to 25
inches, isolated amounts of 35 inches.

Eastern Guatemala and southern Belize: 10 to 20 inches, isolated
amounts of 25 inches.

Jamaica: 5 to 10 inches, isolated amounts of 15 inches over southern
areas.

Southern Haiti and the Cayman Islands: 3 to 5 inches, isolated
amounts of 10 inches.

This rainfall may lead to life-threatening flash flooding and river
flooding, along with landslides in areas of higher terrain.

STORM SURGE:  A dangerous storm surge will raise water levels by as
much as 6 to 9 feet above normal tide levels in areas of onshore
winds along the coast of Nicaragua within the hurricane warning
area, and 3 to 5 feet above normal tide levels along the coast of
Honduras within the tropical storm warning area.  Near the coast,
the surge will be accompanied by large and destructive waves.

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.
