DISCUSSION AND OUTLOOK ---------------------- At 1200 PM CST (1800 UTC), the center of Tropical Depression Eta was located near latitude 17.9 North, longitude 86.9 West. The depression is moving toward the north-northeast near 6 mph (10 km/h). A turn toward the northeast and a faster forward speed are expected this afternoon, with this motion continuing through early Sunday. On the forecast track, the center of Eta will move across the northwestern Caribbean Sea today, approach the Cayman Islands Saturday, and be near central or western Cuba Saturday night and Sunday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Eta is forecast to become a tropical storm again this afternoon or tonight, with further strengthening likely through early Sunday. The estimated minimum central pressure 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.

Southeastern Mexico and Jamaica: An additional 2 to 5 inches (50 to 125 mm), isolated maximum storm totals of 15 inches (380 mm).

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