A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Interests elsewhere in Nicaragua and Honduras should monitor the progress of this system. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 100 PM EST (1800 UTC), the center of Tropical Storm Eta was located near latitude 14.9 North, longitude 78.1 West. Eta is moving toward the west near 15 mph (24 km/h), and this motion with some decrease in forward speed is expected to continue through tonight. A slower motion toward the west-southwest is forecast on Monday and Tuesday. On the forecast track, the center of Eta is expected to be near the northeastern coasts of Nicaragua and Honduras by Tuesday morning. Maximum sustained winds have increased to near 50 mph (85 km/h) with higher gusts. Strengthening is forecast during the next couple of days, and Eta is expected to become a hurricane by late Monday. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The estimated minimum central pressure is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected in the Hurricane Warning area by early Tuesday, with tropical storm conditions possible in this area by late Monday. Tropical storm conditions are expected in the Tropical Storm Warning area by late Monday, and hurricane conditions are possible in the Hurricane Watch area by early Tuesday. RAINFALL: Eta is expected to produce the following rainfall amounts through Thursday evening: Central and northern Nicaragua into much of Honduras: 15 to 25 inches (380 to 635 mm), isolated amounts of 35 inches (890 mm). Eastern Guatemala and southern Belize: 10 to 20 inches (255 to 510 mm), isolated amounts of 25 inches (635 mm). Jamaica: 5 to 10 inches (125 to 255 mm), isolated amounts of 15 inches (380 mm) over southern areas. Southern Haiti and the Cayman Islands: 3 to 5 inches (75 to 125 mm), isolated amounts of 10 inches (255 mm). This rainfall may lead to life-threatening flash flooding and river flooding, along with landslides in areas of higher terrain. STORM SURGE: A dangerous storm surge will raise water levels by as much as 6 to 9 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.
