The governments of Nicaragua and Honduras continue to issue warnings on heavy rain and flooding in those countries, and interests in Nicaragua and Honduras should continue to monitor the progress of this system. Interests in Belize, western Cuba, and the Cayman Islands should also monitor the progress of this system. 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). 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 Monday morning: Portions of Honduras, Guatemala and Belize: An additional 15 to 30 inches (380 to 760 mm), isolated maximum storm totals of 40 inches (1000 mm) in eastern Honduras. Portions of Nicaragua, El Salvador and Costa Rica: An additional 15 to 20 inches (380 to 510 mm), isolated maximum storm totals of 40 inches (1000 mm) in eastern Nicaragua. Southeastern Mexico: 5 to 15 inches (125 to 380 mm), isolated maximum totals of 20 inches (510 mm). Jamaica: An additional 3 to 5 inches (75 to 125 mm), isolated maximum storm totals totals of 15 inches (380 mm). The Cayman Islands into western Cuba: 10 to 25 inches (255 to 635 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. Flash flooding and river flooding will be possible across Jamaica, southeast Mexico, southern Haiti, the Cayman Islands and western Cuba. 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.
