WATCHES AND WARNINGS
There are no coastal watches or warnings in effect.
Although the coastal warnings have been discontinued, the

heavy rain and flooding in those countries, and interests in
Nicaragua and Honduras should continue to monitor the progress of
this system. Interests in Belize, western Cuba, and the Cayman
Islands should also monitor the progress of this system.
DISCUSSION AND OUTLOOK
At 300 PM CST (2100 UTC), the center of Tropical Storm Eta was
located near latitude 13.9 North, longitude 85.7 West. Eta is moving
toward the west near 7 mph (11 km/h). A west-northwestward motion
at a faster forward speed is expected this evening through Thursday
morning. A turn toward the north, and then northeast is forecast
Thursday night and Friday. On the forecast track, the center of Eta
is expected across Honduras later this afternoon through Thursday
morning. The system is forecast to emerge over the Gulf of Honduras
or the northwestern Caribbean Sea Thursday night and Friday.
Maximum sustained winds are now near 40 mph (65 km/h) with higher
gusts. Continued weakening will occur while Eta moves over land
during the next day or two, and Eta should become a tropical
depression during the next few hours. Re-intensification is
possible once the center of Eta reached the Caribbean Sea.
Tropical-storm-force winds extend outward up to 45 miles (75 km)
from the center.
The estimated minimum central pressure is 999 mb (29.50 inches).

Portions of Honduras, Guatemala and Belize: An additional 15 to 30

(1000 mm) in eastern Honduras.
Portions of Nicaragua, El Salvador and Costa Rica: An additional 15
to 20 inches (380 to 510 mm), isolated maximum storm totals of 40
inches (1000 mm) in eastern Nicaragua.
Southeastern Mexico: 5 to 15 inches (125 to 380 mm), isolated
maximum totals of 20 inches (510 mm).
Jamaica: An additional 3 to 5 inches (75 to 125 mm), isolated

The Cayman Islands into western Cuba: 10 to 25 inches (255 to 635
mm), isolated maximum totals of 30 inches (760 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, southern
Haiti, the Cayman Islands and western Cuba.
STORM SURGE: Water levels along the coasts of Nicaragua and
Honduras should decrease this evening.
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.
