DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the center of Tropical Storm Nana was
located near latitude 17.0 North, longitude 85.9 West. Nana is
moving toward the west near 15 mph (24 km/h), and 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 and the Bay Islands this evening, and the center should 
make landfall on the coast of Belize tonight or early Thursday.
 
Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
While Nana has not strengthened during the past several hours, 
strengthening is expected before landfall, and Nana could become a 
hurricane by the time the center reaches the coast of Belize.
 
Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.
 
The estimated minimum central pressure is 999 mb (29.50 inches).
