DISCUSSION AND OUTLOOK
----------------------
At 700 PM CDT (0000 UTC), an Air Force Reserve Hurricane Hunter
aircraft located the center of Tropical Storm Nana near latitude
17.0 North, longitude 86.8 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
continue to pass just north of the Bay Islands of Honduras during
the next couple of hours, and the center should make landfall on the
coast of Belize later tonight or early Thursday.
 
Maximum sustained winds are near 60 mph (95 km/h) with higher
gusts. While Nana has not strengthened over 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 latest minimum central pressure estimated from reconnaissance 
aircraft data is 994 mb (29.35 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected in the Hurricane Warning
area in Belize tonight and early Thursday, with tropical storm
conditions expected by tonight.  Tropical storm conditions are
expected in the Tropical Storm Warning area in Belize, Guatemala,
and Mexico tonight, with hurricane conditions possible in the
Hurricane Watch area tonight.  Tropical storm conditions are
expected in Isla Roatan and the Bay Islands tonight.  Tropical
storm conditions are possible within the watch area in Honduras.
 
STORM SURGE:  A dangerous storm surge will raise water levels by as
much as 1 to 3 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 the following rainfall
accumulations through Friday:
 
Northern coast of Honduras: 1 to 3 inches
 
Belize, Guatemala and the Mexican states of Chiapas and Tabasco: 3
to 6 inches, isolated totals of 8 inches
 
The southeast portion of the Mexican state of Quintana Roo:  2 to 4
inches
 
The eastern portions of the Mexican states of Veracruz and Oaxaca: 6
to 8 inches, isolated totals of 12 inches
 
These rainfall amounts may produce life threatening flash floods and
mudslides
 
SURF:  Swells generated by Nana are affecting the Cayman Islands,
and are spreading along the coasts of Honduras and Belize, and
along the east coast of the Yucatan peninsula of Mexico. These
swells are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.
