DISCUSSION AND OUTLOOK ---------------------- At 900 PM CST (0300 UTC), the center of Tropical Depression Eta was located near latitude 16.6 North, longitude 87.8 West. The depression is moving toward the north near 8 mph (13 km/h). A turn toward the northeast is expected on Friday, with this motion continuing through early Sunday. On the forecast track, the center of Eta will be over the western Caribbean Sea through Friday, approach the Cayman Islands Saturday and Saturday night, and be near Cuba on Sunday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Eta is forecast to become a tropical storm again on Friday, with further strengthening possible through early Sunday. The estimated minimum central pressure based on nearby surface observations is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Eta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT4.shtml. 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).

These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
