DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the center of Tropical Storm Barry was
located near latitude 28.7 North, longitude 90.9 West. Barry is
moving toward the west-northwest near 6 mph (9 km/h). A motion
toward the northwest should begin during the next several hours,
followed by a turn toward the north Saturday night or Sunday. On
the forecast track, the center of Barry will approach the central or
southeastern coast of Louisiana through tonight and then make
landfall over the central Louisiana coast on Saturday. After
landfall, Barry is expected to move generally northward through the
Mississippi Valley through Sunday night.

Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts. Strengthening is forecast before landfall, and Barry is
expected to be a hurricane when the center reaches the Louisiana
coast on Saturday. Weakening is expected after Barry moves inland.

Tropical-storm-force winds extend outward up to 175 miles (280 km)
from the center. An oil rig located southwest of the Mouth of the
Mississippi River recently reported sustained winds of 74 mph and a
wind gust of 85 mph at an elevation of 295 ft.

The estimated minimum central pressure is 993 mb (29.33 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 Biloxi MS...3 to 5 ft
Intracoastal City to the Mouth of the Atchafalaya River...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.
These rains are expected to lead to dangerous, life threatening
flooding over portions of the central Gulf Coast into the Lower
Mississippi Valley. 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. By early next week, Barry is
expected to produce rainfall accumulations of 4 to 8 inches across
western portions of the Tennessee Valley.

WIND: Hurricane conditions are expected in the Hurricane Warning
area tonight or Saturday, with tropical storm conditions currently
spreading across the area. Hurricane conditions are possible within
the Hurricane Watch area tonight or Saturday morning. Tropical
storm conditions are occurring across the Tropical Storm Warning
area in southeastern Louisiana at this time. Tropical storm
conditions are possible in the Tropical Storm Watch area by tonight
or Saturday. Wind gusts to tropical-storm force in squalls are
possible along portions of the coasts of Alabama and the western
Florida Panhandle through Saturday night.

TORNADOES: A couple tornadoes are possible late tonight through
Saturday across southeast Louisiana and southern Mississippi.
