DISCUSSION AND OUTLOOK ---------------------- At 600 PM CST (0000 UTC), the center of Tropical Depression Eta was located near latitude 16.0 North, longitude 87.8 West. The depression is moving toward the north-northwest near 8 mph (13 km/h), and a turn toward the north is forecast during the next several hours. A turn toward the northeast is expected on Friday, with this motion continuing through Saturday night. 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 remain near 35 mph (55 km/h) over water, with higher gusts. Strengthening is forecast, and Eta is expected to re-gain tropical storm strength on Friday. 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). This rainfall will lead to catastrophic, life-threatening flash flooding and river flooding, along with landslides in areas of higher terrain of Central America. 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. WIND: Tropical storm conditions are possible in the Cayman Islands Saturday or Saturday night. 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.
