DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Tropical Storm Nana was located near latitude 17.0 North, longitude 80.9 West. Nana is moving toward the west near 18 mph (30 km/h), and this general motion is expected to continue through Wednesday. A westward or west-southwestward motion is expected Wednesday night and Thursday. On the forecast track, Nana will be moving near but north of the coast of Honduras on Wednesday and likely be approaching the coast of Belize Wednesday night and early Thursday. Data from an Air Force Reserve reconnaissance aircraft indicate that the maximum sustained winds have increased to near 60 mph (95 km/h) with higher gusts. Additional strengthening is expected, and Nana is forecast to become a hurricane on Wednesday or Wednesday night before it reaches the coast of Belize. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The estimated minimum central pressure is 999 mb (29.50 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical Storm conditions are expected within the warning area in Belize by late Wednesday, with hurricane conditions likely over a portion of the area Wednesday night and early Thursday. Tropical storm conditions are expected within the warning area in Mexico and Guatemala late Wednesday. Tropical storm conditions are possible within the watch area in Honduras on Wednesday. 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 on Wednesday and Wednesday night. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
