A Hurricane Watch is in effect for…

* The northeastern coast of Nicaragua from the Honduras/Nicaragua

A Hurricane Watch means that hurricane conditions are possible

before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.

progress of this system. Additional watches or warnings will
likely be required for portions of these countries later today.

For storm information specific to your area, please monitor
products issued by your national meteorological service.

DISCUSSION AND OUTLOOK

At 700 AM EST (1200 UTC), the center of Tropical Storm Eta was
located near latitude 14.9 North, longitude 76.7 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 today and
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, and Eta is expected to become a
hurricane by 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 possible in the Hurricane Watch
area by early Tuesday, with tropical storm conditions possible in
this area by Monday night.

Jamaica, the Cayman Islands, and the southern coast of Hispaniola.
Across northern Honduras and northern Nicaragua, rainfall totals of
10 to 20 inches, with local maximum amounts of 30 inches are
expected. This rainfall may lead to life-threatening flash flooding
and river flooding, along with landslides in areas of higher
terrain.
