DISCUSSION AND OUTLOOK
At 800 PM EDT (0000 UTC), the center of Tropical Depression Fourteen
was located by an Air Force Reserve Hurricane Hunter aircraft near
latitude 18.3 North, longitude 84.7 West. The depression is moving
toward the northwest near 13 mph (20 km/h). A slower northwestward
motion is expected over the next couple of days, followed by an
increase in speed by Sunday and Monday. On the forecast track, the
center of the system will approach the east coast of the Yucatan

northeastern part of the Yucatan Peninsula Saturday night and move
over the central Gulf of Mexico toward the northwestern Gulf on
Sunday and Monday.
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 tonight
or early Saturday. The system could be near hurricane strength when
it reaches the Yucatan Peninsula of Mexico late Saturday. Additional
strengthening is forecast Sunday and Monday as the system moves over
the central Gulf of Mexico.
The estimated minimum central pressure based on data from the
Hurricane Hunter plane is 1009 mb (29.80 inches).
