DISCUSSION AND OUTLOOK
----------------------
At 700 AM CDT (1200 UTC), the disturbance was centered near latitude
22.0 North, longitude 94.9 West. The system is moving toward the north-northwest near 5 mph (7 km/h). A slow northwestward to
northward motion is expected over the next day or so, followed by a
faster motion to the northeast beginning late Tuesday. On the
forecast track, the disturbance is expected to move just offshore of
the northern Gulf Coast of Mexico through Tuesday, and approach the
Louisiana and Upper Texas coastline on Wednesday.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
The disturbance is expected to become a tropical storm later today,
with more significant intensification forecast to occur on Tuesday
and Wednesday. The system is forecast to become a hurricane before
it reaches the northwestern U.S. Gulf Coast.
* Formation chance through 48 hours... high...90 percent.
* Formation chance through 7 days...high...90 percent.

Tropical-storm-force winds extend outward up to 185 miles (295 km)
from the center.

The estimated minimum central pressure is 1003 mb (29.62 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are possible within the watch
area along the northern coast of Mexico and extreme southern Texas
beginning Tuesday.

RAINFALL: Potential Tropical Cyclone Six is expected to bring storm
total rainfall of 4 to 8 inches, with local amounts to 12 inches,
from the coast of far northeast Mexico northward along portions of
the southern Texas Coast and across southern Louisiana and southern
Mississippi into Thursday morning. This rainfall would lead to the
risk of considerable flash and urban flooding.

For a complete depiction of forecast rainfall associated with
Potential Tropical Cyclone Six, please see the National Weather
Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at1.shtml?rainqpf and the Flash Flood Risk
graphic at hurricanes.gov/graphics_at1.shtml?ero.

STORM SURGE: Minor coastal flooding is possible along the coast of
Mexico in areas of onshore winds.

SURF: Swells generated by this system are affecting portions of the
Gulf coast of Mexico and are expected to spread northwestward across
the northwestern Gulf of Mexico coastline through midweek. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
