DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 800 AM EDT (1200 UTC), the center of Tropical Storm Nate was located near latitude 13.9 North, longitude 83.4 West. Nate is moving toward the northwest near 8 mph (13 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 Nate should move across northeastern Nicaragua and eastern Honduras today and then over the northwestern Caribbean Sea tonight and Friday. The center is expected to approach the coast of the Yucatan peninsula late Friday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Little change in strength is expected today as the center of Nate moves across northeastern Nicaragua and eastern Honduras. Strengthening is likely over the northwestern Caribbean Sea tonight and Friday. Tropical-storm-force winds extend outward up to 60 miles (95 km) mainly over water to the east of the center. The estimated minimum central pressure is 999 mb (29.50 inches). Puerto Cabezas recently reported a pressure of 1001 mb (29.56 inches) HAZARDS AFFECTING LAND ---------------------- RAINFALL: Nate 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 today and tonight. Tropical storm and hurricane conditions are possible within the watch area in Mexico beginning late Friday. SURF: Swells generated by Nate 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.
