protect life and property from rising water and the potential for
other dangerous conditions.  Promptly follow evacuation and other
instructions from local officials.

DISCUSSION AND OUTLOOK
----------------------
At 400 AM CDT (0900 UTC), the broad circulation center of Tropical
Storm Barry was located near latitude 28.1 North, longitude 90.2
West. Barry is moving toward the west-northwest near 5 mph (7 km/h).
A track toward the northwest is expected to begin later today,
followed by a turn toward the north on Saturday. On the forecast
track, the center of Barry will be near or over the central or
southeastern coast of Louisiana tonight or Saturday, and then
move inland into the Lower Mississippi Valley on Sunday.

Data from an Air Force Reserve reconnaissance aircraft, a few
hours ago, indicate that the maximum sustained winds remain near 50
mph (85 km/h) with higher gusts.  Some strengthening is expected
during the next day or so, and Barry could become a hurricane
tonight or early Saturday when the center is near the Louisiana
coast.  Weakening is expected after Barry moves inland.

Tropical-storm-force winds extend outward up to 175 miles (280 km)
to the east of the center.

The estimated minimum central pressure estimated from a surface
observations nearby was 1000 mb (29.53 inches).


HAZARDS AFFECTING LAND
----------------------
Key Messages for Barry can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.

STORM SURGE:  The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline.  The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Mouth of the Atchafalaya River to Shell Beach...3 to 6 ft
Shell Beach to the Mississippi/Alabama border...2 to 4 ft
Intracoastal City to the Mouth of the Atchafalaya River...3 to 5 ft
Lake Pontchartrain...2 to 4 ft

Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances. For
information specific to your area, please see products issued by
your local National Weather Service forecast office.

RAINFALL:  Barry is expected to produce total rain accumulations of
10 to 20 inches over southeast Louisiana and southwest Mississippi,
with isolated maximum amounts of 25 inches. These rains are expected
to lead to dangerous, life-threatening flooding over portions of the
central Gulf Coast into the Lower Mississippi Valley.  Over the
remainder of the Lower Mississippi Valley, total rain accumulations
of 4 to 8 inches are expected, with isolated maximum amounts of 12
inches.

WIND:  Hurricane conditions are expected in the Hurricane Warning
area tonight or Saturday morning, with tropical storm conditions
expected to begin later today.  Hurricane conditions are possible
within the Hurricane Watch area by tonight or Saturday morning.
Tropical Storm conditions are expected to spread across the Tropical
Storm Warning area starting early today, with tropical storm
conditions possible in the Tropical Storm Watch area
by tonight or Saturday.

TORNADOES:  A few tornadoes are possible today and tonight across
southeast Louisiana, far southern Mississippi, and the Alabama
coast.
