DISCUSSION AND OUTLOOK

At 1100 AM EDT (1500 UTC), the center of Tropical Storm Nana was
located near latitude 17.1 North, longitude 84.6 West. Nana is
moving toward the west near 17 mph (28 km/h), and this general
motion with some decrease in forward speed is expected 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 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. Strengthening is expected, and Nana is forecast to become a
hurricane tonight before it reaches the coast of Belize. Weakening
is expected after landfall.

Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.

The estimated minimum central pressure is 998 mb (29.47 inches).

expected in the Tropical Storm Warning area in Belize, Guatemala,
and Mexico by tonight, with hurricane conditions possible in the
Hurricane Watch area tonight. Tropical storm conditions are
possible within the watch area in Honduras, including Isla Roatan

STORM SURGE: A dangerous storm surge will raise water levels by as
