DISCUSSION AND OUTLOOK
At 300 AM CST (0900 UTC), the poorly-defined center of Tropical
Depression Eta was estimated near latitude 14.5 North, longitude
87.0 West. The depression is moving toward the west-northwest near 8
mph (13 km/h). A west-northwestward to northwestward motion is
expected today. A turn toward 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 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
Maximum sustained winds are near 30 mph (45 km/h) with higher gusts.
Eta will likely degenerate to a remnant low or trough of low
pressure this morning. However, re-intensification is forecast
once the center of Eta moves over the northwestern Caribbean Sea.
The estimated minimum central pressure is 1006 mb (29.71 inches).

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.
