DISCUSSION AND OUTLOOK
At 800 AM EDT (1200 UTC), the center of Tropical Depression Fourteen
was located near latitude 16.2 North, longitude 84.2 West. The
depression is moving toward the west-northwest near 12 mph (19
km/h), and this general motion is forecast to continue this morning.
A turn toward the northwest with a decrease in forward speed is
expected by this afternoon and is forecast to continue through at
least Sunday. On the forecast track, the center of the system will
move near or just offshore the coast of northern Honduras, including
the Bay Islands, today and approach the east coast of the Yucatan
Peninsula of Mexico on Saturday. The center is then expected to
cross the Yucatan Peninsula Saturday night and move into the
south-central Gulf of Mexico on Sunday.
Maximum sustained winds are near 35 mph (55 km/h) with higher
gusts. Strengthening is forecast during the next couple of days,
and the depression is expected to become a tropical storm later
today. The system is forecast to be near or at hurricane strength
when it reaches the Yucatan Peninsula of Mexico late Saturday. Some
weakening is expected as it traverses the Yucatan Peninsula Saturday
night. Afterward, restrengthening is forecast on Sunday as it moves
offshore and enters the southern Gulf of Mexico
The estimated minimum central pressure is 1008 mb (29.77 inches).
