DISCUSSION AND OUTLOOK ---------------------- At 600 PM CST (0000 UTC), the center of Tropical Depression Eta was located near latitude 17.7 North, longitude 85.8 West. The depression is moving toward the northeast near 8 mph (13 km/h). A northeastward motion at a faster forward speed is expected through early Sunday. A turn toward the north and northwest are expected late Sunday. On the forecast track, the center of Eta will move across the northwestern Caribbean Sea tonight, approach the Cayman Islands Saturday, be near central Cuba Saturday night and Sunday, and approach the Florida Keys or south Florida late Sunday. Reports from a NOAA Hurricane Hunter aircraft indicate that maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Eta is forecast to become a tropical storm again tonight, with further strengthening likely through early Sunday. The estimated minimum central pressure is 1002 mb (29.59 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 Wednesday morning: Portions of Central America: An additional 2 to 5 inches (50 to 125 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: 8 to 16 inches (200 to 400 mm), isolated maximum totals of 25 inches (650 mm). The Bahamas and Southern Florida, including the Keys: 5 to 10 inches (125 to 255 mm), isolated maximum totals of 15 inches (380 mm). The threat of life-threatening flooding will continue across portions of Central America, along with landslides in areas of higher terrain. Significant, life-threatening flash flooding and river flooding is possible in the Cayman Islands and Cuba. Flash flooding and urban flooding is also possible for Jamaica, southeast Mexico, the Bahamas and Southern Florida. STORM SURGE: A dangerous storm surge will raise water levels by as much as 2 to 4 feet above normal tide levels along the coast of Cuba near and to the east of where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. WIND: Tropical storm conditions are expected in the Cayman Islands Saturday afternoon and evening. Tropical storm conditions are expected in the warning area in Cuba Saturday night and Sunday, and they are possible in the watch area in Cuba Saturday night and Sunday. SURF: Swells generated by Eta are expected to spread northeastward and affect the Cayman Islands, Jamaica, and the southern coast of Cuba 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.
