Interests elsewhere in Honduras, the Bay Islands, western Cuba and the Yucatan Peninsula should monitor the progress of the depression. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 AM EDT (0900 UTC), the center of Tropical Depression Sixteen was located near latitude 13.3 North, longitude 83.3 West. The depression is moving toward the northwest near 7 mph (11 km/h), and this motion is expected to continue this morning. A north- northwestward motion at a faster forward speed is forecast to begin later today and continue through Friday night. On the forecast track, the center of the depression should move across northeastern Nicaragua and eastern Honduras later today and then over the northwestern Caribbean Sea Thursday night and Friday. The center is expected to approach the coast of the Yucatan peninsula late Friday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. The depression could strengthen to a tropical storm before it moves inland over northeastern Nicaragua today. Strengthening is likely over the northwestern Caribbean Sea Thursday night and Friday. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: The depression is expected to produce the following rain accumulations through Friday night: Nicaragua...15 to 20 inches, isolated 30 inches Costa Rica and Panama...5 to 10 inches, isolated 20 inches Honduras and Belize...2 to 5 inches, isolated 8 inches Eastern portions of the Yucatan peninsula...4 to 8 inches, isolated 12 inches Heavy rainfall will occur over a wide area, including locations well away from the center along the Pacific coast of Central America. This rainfall could cause life-threatening flash floods and mudslides. WIND: Tropical storm conditions are expected within portions of the warning area in Nicaragua and Honduras late today and tonight. Tropical storm and hurricane conditions are possible within the watch area in Mexico beginning late Friday. SURF: Swells generated by the cyclone are affecting portions of the coast of Nicaragua, and will begin to affect other land areas around the northwestern Caribbean later this week. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
