For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Tropical Storm Bonnie was located just inland over southeastern Nicaragua near latitude 10.9 North, longitude 83.8 West. Bonnie is moving toward the west near 16 mph (26 km/h), and a continued westward motion with a gradual decrease in forward speed is expected into Saturday night. A west-northwestward motion is expected to begin late Saturday night or on Sunday and continue into Monday. On the forecast track, the system will move across southern Nicaragua and northern Costa Rica tonight and emerge over the eastern Pacific Ocean on Saturday. The system will then move offshore of but parallel to the coasts of El Salvador, Guatemala, and southern Mexico Saturday through Monday. Reports from an Air Force Reserve Hurricane Hunter aircraft indicate that before landfall maximum sustained winds increased to near 50 mph (85 km/h) with higher gusts. Weakening is likely while the center of Bonnie crosses Nicaragua and Costa Rica. The storm is forecast to re-intensify over the eastern Pacific Saturday night and Sunday. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The minimum central pressure estimated from the Hurricane Hunter aircraft data is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Storm Bonnie can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC. RAINFALL: Bonnie will produce heavy rain across portions of Nicaragua and Costa Rica through Saturday. The following storm total rainfall amounts are expected: Nicaragua and Costa Rica: 4 to 8 inches, localized 12 inches. This rainfall is expected to result in life-threatening flash flooding and mudslides. WIND: Tropical storm conditions are occurring in the Tropical Storm Warning area along the Caribbean coasts of Nicaragua and Costa Rica, and these will spread westward to the Pacific coast within the warning areas overnight. STORM SURGE: Storm surge could raise water levels by as much as 1 to 3 feet above normal tide levels along the immediate coast of Nicaragua near and to the north of where the center makes landfall.
