DISCUSSION AND OUTLOOK
----------------------
At 900 PM CST (0300 UTC), the center of Tropical Depression Eta 
was located near latitude 14.2 North, longitude 86.3 West. The 
depression is moving toward the west-northwest near 7 mph (11 km/h). 
A northwestward motion is expected later tonight through Thursday 
morning. A turn toward the north, and then the northeast is forecast 
to occur Thursday night and Friday.  On the forecast track, the 
center of Eta is expected to move across Honduras through Thursday 
afternoon, and emerge over the Gulf of Honduras by Thursday night. 
Eta is forecast to approach the Cayman Islands and western or 
central Cuba this weekend.
 
Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Additional weakening is expected while Eta remains over land, and
Eta will likely degenerate to a remnant low or trough of low
pressure on Thursday.  However, re-intensification is forecast once
the center of Eta moves over the northwestern Caribbean Sea.
 
The estimated minimum central pressure is 1003 mb (29.62 inches).

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

products from your local weather office.
