DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 100 AM CDT (0600 UTC), the disturbance was centered near latitude
24.5 North, longitude 89.9 West. The system is moving generally
toward the north-northwest near 8 mph (13 km/h). A turn toward the
northwest should occur by Tuesday morning, and that motion is
expected to continue into Wednesday. On the forecast track, the
disturbance is expected to be near the Louisiana coast on Wednesday.

Maximum sustained winds are near 40 mph (65 km/h) with higher
gusts. Some slight strengthening is possible before the system
reaches the coast.

Upper-level winds are expected to be marginally conducive for some
additional development of this system during the next day or two,
and a tropical or subtropical cyclone is likely to form during that
time.
* Formation chance through 48 hours...high...80 percent
* Formation chance through 5 days...high...80 percent

Tropical-storm-force winds extend outward up to 205 miles (335 km)
to the north and east of the center.

The estimated minimum central pressure is 1000 mb (29.53 inches).


HAZARDS AFFECTING LAND

WIND:  Tropical storm conditions are expected to first reach the
coast within the warning area by Tuesday afternoon. Tropical storm
conditions are possible in the watch area on Wednesday.

RAINFALL:  The disturbance is expected to produce total rain
accumulations of 4 to 8 inches with isolated maximum amounts of
10 inches over southeastern Louisiana, southern Mississippi,
southern Alabama, and the Florida Panhandle through Wednesday
evening.
