DISCUSSION AND OUTLOOK
———————-
At 700 PM EST (0000 UTC), the center of Hurricane Eta was located
near latitude 14.4 North, longitude 82.4 West. Eta is moving toward
the west-southwest near 9 mph (15 km/h), and this general motion is
expected to continue through early Tuesday. A slower westward or
west-northwestward motion is forecast to begin by Tuesday afternoon
and continue through Thursday. On the forecast track, the center of
Eta is expected to make landfall along the coast of Nicaragua within
the Hurricane Warning area early Tuesday. The center of Eta is
forecast to move farther inland over northern Nicaragua through
Wednesday night, and then move across central portions of Honduras
on Thursday.

Maximum sustained winds have increased to near 150 mph (240 km/h)
with higher gusts. Eta is a category 4 hurricane on the Saffir-
Simpson Hurricane Wind Scale. Additional strengthening is forecast
until Eta reaches the coast of Nicaragua. Weakening will begin
after the cyclone moves inland. An Air Force Reserve hurricane
hunter aircraft is currently en route to investigate Eta.

Hurricane-force winds extend outward up to 25 miles (35 km) from
the center and tropical-storm-force winds extend outward up to 125
miles (205 km).

The estimated minimum central pressure is 934 mb (27.58 inches).

HAZARDS AFFECTING LAND
———————-

WIND: Catastrophic wind damage is expected where Eta’s eyewall
moves onshore within the Hurricane Warning area beginning tonight,
with tropical storm conditions beginning within the next few hours.
Tropical storm conditions are expected in the Tropical Storm Warning
area tonight, and hurricane conditions are possible in the Hurricane
Watch area by early Tuesday. Tropical Storm conditions are possible
in the Tropical Storm Watch area by early Tuesday.

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

Much of Nicaragua and Honduras: 15 to 25 inches (380 to 635 mm),
isolated amounts of 35 inches (890 mm).

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

Portions of Panama and Costa Rica: 10 to 15 inches (255 to 380 mm),
isolated amounts of 25 inches (635 mm).

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

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

This rainfall will lead to catastrophic, life-threatening flash
flooding and river flooding, along with landslides in areas of
higher terrain of Central America. Flash flooding and river
flooding are also possible across Jamaica, southeast Mexico, El
Salvador, southern Haiti, and the Cayman Islands.

STORM SURGE: A dangerous storm surge will raise water levels by as
much as 12 to 18 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.
