RAINFALL:  Eta is expected to produce the following rainfall
amounts through Tuesday morning:
 
Portions of Central America: An additional 5 to 10 inches (125 to
255 mm), isolated maximum storm totals of 40 inches (1000 mm) in
eastern Honduras and eastern Nicaragua.
 
Southeastern Mexico and Jamaica: An additional 2 to 5 inches (50 to
125 mm), isolated maximum storm totals of 15 inches (380 mm).
 
The Cayman Islands into portions of Cuba: 10 to 20 inches (255 to
510 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.  Significant, life-threatening
flash flooding and river flooding is possible in the Cayman Islands
and Cuba.  Flash flooding and river flooding is expected for Jamaica
and southeast Mexico.
 
WIND: Tropical storm conditions are possible in the Cayman Islands
Saturday or Saturday night.
 
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 couple of days.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
