DISCUSSION AND OUTLOOK
----------------------
At 200 PM EDT (1800 UTC), the center of Tropical Storm Nana was
located near latitude 16.7 North, longitude 78.4 West. Nana is
moving toward the west near 18 mph (30 km/h), and this general
motion is expected to continue through 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 on
Thursday.
 
Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts. Additional strengthening is forecast during the next 48
hours, and Nana could become a hurricane just prior to landfall on
Thursday.
 
Tropical-storm-force winds extend outward up to 80 miles (130 km)
from the center, mainly northeast through northwest of the center.
 
The estimated minimum central pressure based on data from the
reconnaissance aircraft is 1002 mb (29.59 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions are possible within the watch
areas by late 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
2 to 4 inches across northern Honduras, Belize, and the southeast
portion of the Mexican state of Quintana Roo.
 
SURF:  Swells generated by this system are affecting portions of the
southern coast of Jamaica, and will continue into Wednesday morning.
These swells are likely to cause life-threatening surf and rip
current conditions.  Please consult products from your local weather
office.
