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).
