DISCUSSION AND OUTLOOK
----------------------
At 100 PM CDT (1800 UTC), the center of Tropical Storm Barry was
located near latitude 29.8 North, longitude 92.1 West.  Barry is
moving toward the northwest near 6 mph (9 km/h), and a turn toward
the north-northwest is expected tonight, followed by a turn toward
the north on Sunday.  On the forecast track, the center of Barry
will move through southern Louisiana this afternoon, into central
Louisiana tonight, and into northern Louisiana on Sunday.
Maximum sustained winds are now near 70 mph (115 km/h) with higher
gusts, and these winds are located over water to the southeast of
the center.  Weakening is expected as Barry moves farther inland,
and it is forecast to weaken to a tropical depression on Sunday.
Tropical-storm-force winds extend outward up to 175 miles (280 km)
from the center.  The National Ocean Service station at Eugene
Island, Louisiana recently reported sustained winds of 61 mph and a
wind gust of 72 mph.
The estimated minimum central pressure is 996 mb (29.41 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...2 to 4 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 and southeast Louisiana and
southwest Mississippi, with isolated maximum amounts of 25 inches.
Across the remainder of the Lower Mississippi Valley and western
portions of the Tennessee 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 the Hurricane
and Tropical Storm Warning areas to the east of the center.  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:  A few tornadoes are possible through tonight across
the southeast Louisiana, southern Mississippi, and southern Alabama.
