DISCUSSION AND OUTLOOK
At 100 AM EST (0600 UTC), the center of Hurricane Eta was located
near latitude 13.8 North, longitude 84.4 West. Eta is moving toward
the west near 6 mph (9 km/h). A faster west-northwestward motion is
expected through early Thursday. A turn toward the north, and then
north-northeast is forecast Thursday night and Friday. On the
forecast track, the center of Eta is expected to move farther inland
over northern Nicaragua through this morning, and then move across
the central portions of Honduras through Thursday morning. The
system is forecast to emerge over the northwestern Caribbean Sea
Thursday night or Friday.
Maximum sustained winds have decreased to near 85 mph (140 km/h)
with higher gusts. Rapid weakening will occur over the next couple
of days while the center of Eta moves inland over Nicaragua and
Hurricane-force winds extend outward up to 25 miles (35 km) from
the center and tropical-storm-force winds extend outward up to 115
miles (185 km).
The estimated minimum central pressure is 980 mb (28.94 inches).

WIND: Significant wind damage is expected within the Hurricane
Warning area and also across inland areas of northeastern
Nicaragua near the path of the center. Tropical storm conditions
are expected in the Tropical Storm Warning area through this
RAINFALL: Eta is expected to produce the following rainfall amounts
through Sunday morning:
Much of Nicaragua and Honduras: 15 to 25 inches (380 to 635 mm),
isolated maximum totals of 40 inches (1000 mm) in northeast
Nicaragua and eastern Honduras.
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).
El Salvador and southeast Mexico: 5 to 10 inches (125 to 255 mm),
isolated amounts of 15 inches (380 mm)
Jamaica, Southern Haiti, the Cayman Islands: An additional 3 to 5
inches (75 to 125 mm), isolated storm totals of 15 inches (380 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 will be 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 5 to 10 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.
