DISCUSSION AND OUTLOOK
----------------------
At 1000 AM CDT (1500 UTC), the center of Tropical Depression
Seventeen was located near latitude 25.6 North, longitude 94.4 West.
The depression is moving toward the north near 16 mph (26 km/h).  A
motion toward the north-northeast at a faster forward speed is
expected this afternoon through Sunday.  On the forecast track, the
center of the cyclone should move across the northwestern Gulf of
Mexico this afternoon and then move over the northern Gulf coast
tonight or Saturday morning.
Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Some strengthening is expected today, and the depression could
become a tropical storm this afternoon.  The cyclone is then
expected to merge with a cold front and become a post-tropical low
with gale-force winds tonight before the center reaches the Gulf
coast.  An Air Force Reserve Hurricane Hunter aircraft is scheduled
to investigate the depression this afternoon.
The estimated minimum central pressure is 1006 mb (29.71 inches).
HAZARDS AFFECTING LAND
----------------------
WIND: Gale-force winds associated with this system should spread
over portions of the northern Gulf coast tonight and Saturday
morning.
RAINFALL: The depression and rainfall ahead of the system along and
north of the frontal boundary across the Central Gulf coast is
expected to produce total rainfall accumulations of 2 to 4 inches
with maximum totals of 8 inches across the Central Gulf coast into
the Lower Mississippi Valley through Saturday morning.  These rains
may produce flash flooding across the Central Gulf coast into the
Lower Mississippi Valley.
COASTAL FLOODING: Above-normal tides and associated coastal
flooding are possible across portions of the northern Gulf coast.
Please see products from local National Weather Service forecast
offices for additional information.
