DISCUSSION AND OUTLOOK
----------------------
At 100 PM EST (1800 UTC), the center of Tropical Storm Eta was
located near latitude 14.9 North, longitude 78.1 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 Eta is expected to be
near the northeastern coasts of Nicaragua and Honduras by Tuesday
morning.

Maximum sustained winds have increased to near 50 mph (85 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 1000 mb (29.53 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 (380 to 635 mm), isolated amounts of 35 inches (890 mm).

Eastern Guatemala and southern Belize: 10 to 20 inches (255 to 510
mm), isolated amounts of 25 inches (635 mm).

Jamaica: 5 to 10 inches (125 to 255 mm), isolated amounts of 15
inches (380 mm) over southern areas.

Southern Haiti and the Cayman Islands: 3 to 5 inches (75 to 125
mm), isolated amounts of 10 inches (255 mm).

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.
