the north, and then the northeast is forecast to occur tonight and
Friday. On the forecast track, the center of Eta is expected to
move across northwestern Honduras through this afternoon, and
emerge over the Gulf of Honduras by tonight. Eta is forecast to
approach the Cayman Islands and western or central Cuba this
weekend.

Maximum sustained winds are near 30 mph (45 km/h) with higher gusts.
Little change in strength is likely through tonight. After that,
Eta is forecast to intensify over the northwestern Caribbean Sea.

The estimated minimum central pressure is 1005 mb (29.68 inches).

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

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.

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.
