The depression is moving toward the northwest near 9 mph (15 km/h), and this general motion is expected to continue 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 northwestern 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 this weekend. Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. Little change in strength is likely through tonight. After that, Eta is forecast to intensify over the northwestern Caribbean Sea. The estimated minimum central pressure is 1005 mb (29.68 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: 5 to 10 inches (125 to 255 mm), isolated maximum totals of 20 inches (510 mm).

The Cayman Islands into portions of Cuba: 10 to 20 inches (255 to 510 mm), isolated maximum totals of 30 inches (760 mm).

Significant, life-threatening flash flooding and river flooding is possible in the Cayman Islands 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.
