DISCUSSION AND OUTLOOK
----------------------
At 700 PM CDT (0000 UTC), the center of Tropical Storm Barry was
located near latitude 30.7 North, longitude 92.7 West.  Barry is
moving toward the north-northwest near 8 mph (13 km/h) and this
general motion is expected to continue tonight.  A turn toward the
north is expected on Sunday.  On the forecast track, the center of
Barry will move across central Louisiana tonight, through northern
Louisiana on Sunday, and over Arkansas Sunday night and Monday.

Maximum sustained winds have decreased to near 60 mph (95 km/h)
with higher gusts, and these winds are occurring near the coast
to the southeast of the center.  Additional weakening is expected
as the center moves farther inland, and Barry is forecast to weaken
to a depression on Sunday.

Tropical-storm-force winds extend outward up to 175 miles (280 km)
from the center.  A National Ocean Service station at Eugene Island,
Louisiana, has recently reported sustained winds of 47 mph and a
wind gust of 55 mph.  In addition, the Acadiana Regional Airport in
New Iberia, Louisiana, recently reported a wind gust of 61 mph.

The estimated minimum central pressure is 998 mb (29.47 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...

Intracoastal City to Shell Beach...3 to 6 ft
Shell Beach to Biloxi MS...3 to 5 ft
Lake Pontchartrain...3 to 5 ft
Biloxi MS to the Mississippi/Alabama border...1 to 3 ft
Lake Maurepas...1 to 3 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 south-central Louisiana and southwest
Mississippi, with isolated maximum amounts of 25 inches.  Across the
remainder of the Lower Mississippi Valley, total rain accumulations
of 4 to 8 inches are expected, with isolated maximum amounts of 12
inches. This rainfall is expected to lead to dangerous,
life-threatening flooding.

WIND:  Tropical storm conditions are occurring across portions of
the Tropical Storm Warning area, and these conditions should persist
through Sunday morning.  Wind gusts to tropical-storm force in
squalls are possible along portions of the coasts of Mississippi,
Alabama, and the western Florida Panhandle through tonight.

TORNADOES:  Isolated tornadoes will be possible through tonight
across southwest Alabama, southern Mississippi, and southeast
Louisiana.
