DISCUSSION AND OUTLOOK ---------------------- At 200 AM EDT (0600 UTC), the center of Tropical Storm Nana was located near latitude 17.0 North, longitude 81.8 West. Nana is moving toward the west near 18 mph (30 km/h), and this general motion is expected to continue today. A westward or west-southwestward motion is expected tonight and Thursday. On the forecast track, Nana will be moving near but north of the coast of Honduras today and likely be approaching the coast of Belize tonight and early Thursday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Strengthening is expected, and Nana is forecast to become a hurricane later today or tonight before it reaches the coast of Belize. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The minimum central pressure estimated from Air Force Hurricane Hunter aircraft observations is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical Storm conditions are expected within the warning area in Belize by tonight, with hurricane conditions likely over a portion of the area tonight and early Thursday. Tropical storm conditions are expected within the warning area in Mexico and Guatemala by tonight. Tropical storm conditions are possible within the watch area in Honduras today. STORM SURGE: A dangerous storm surge will raise water levels by as much as 3 to 5 feet above normal tide levels along the immediate coast near and to the north of where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Nana is expected to produce rainfall accumulations of 3 to 6 inches in Belize and northern Guatemala. 2 to 4 inches of rain is expected across northern Honduras and the southeast portion of the Mexican state of Quintana Roo. SURF: Swells generated by Nana are affecting portions of the southern coast of Jamaica and the Cayman Islands, and will spread along the coasts of Honduras and Belize today and tonight. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
