DISCUSSION AND OUTLOOK ---------------------- At 700 PM EST (0000 UTC), the eye of Hurricane Eta was located near along the coast of Nicaragua near latitude 13.8 North, longitude 83.7 West. Eta is moving toward the west near 5 mph (7 km/h) A faster westward or west-northwestward motion is expected through early Thursday. A turn toward the north, and then north-northeast is forecast Thursday night and Friday. On the forecast track, the center of Eta is expected to move inland over northern Nicaragua through Wednesday morning, and then move across the central portions of Honduras through Thursday morning. The system is forecast to emerge over the northwestern Caribbean Sea Thursday night or Friday. Maximum sustained winds have decreased to near 110 mph (175 km/h) with higher gusts. Eta is now a strong category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. Rapid weakening will continue as the center moves farther inland tonight and Wednesday. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 115 miles (185 km). During the past couple of hours, a sustained wind of 107 mph (172 km/h) and a gust to 135 (217 km/h) were measured at the Puerto Cabezas, Nicaragua, airport. The estimated minimum central pressure is 965 mb (28.50 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Eta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC. WIND: Catastrophic wind damage is expected where Eta's eyewall tracks within the Hurricane Warning area. Tropical storm conditions are expected in the Tropical Storm Warning area through tonight. RAINFALL: Eta is expected to produce the following rainfall amounts through Sunday morning: Much of Nicaragua and Honduras: 15 to 25 inches (380 to 635 mm), isolated amounts of 35 inches (890 mm). Eastern Guatemala and Belize: 10 to 20 inches (255 to 510 mm), isolated amounts of 25 inches (635 mm). Portions of Panama and Costa Rica: 10 to 15 inches (255 to 380 mm), isolated amounts of 25 inches (635 mm). El Salvador and southeast Mexico: 5 to 10 inches (125 to 255 mm), isolated amounts of 15 inches (380 mm) Jamaica, Southern Haiti, the Cayman Islands: An additional 3 to 5 inches (75 to 125 mm), isolated storm totals of 15 inches (380 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, El Salvador, southern Haiti, and the Cayman Islands. STORM SURGE: A dangerous storm surge will raise water levels by as much as 10 to 15 feet above normal tide levels in areas of onshore winds along the coast of Nicaragua within the hurricane warning area, and 3 to 5 feet above normal tide levels along the coast of Honduras within the tropical storm warning area. Near the coast, the surge will be accompanied by large and destructive waves. 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 few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
