DISCUSSION AND OUTLOOK
----------------------
At 700 PM CDT (0000 UTC), the center of Tropical Storm Barry was
located near latitude 27.8 North, longitude 89.3 West. Barry has
moved little over the past few hours, but a motion toward the west
near 3 mph (5 km/h) is expected to resume later tonight. A turn
toward the northwest is expected on Friday, 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 Friday night or Saturday, and then move inland into the
lower Mississippi Valley on Sunday.

Maximum sustained winds have increased to near 45 mph (75 km/h) with
higher gusts. Strengthening is expected during the next day or two,
and Barry could become a hurricane late Friday 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 140 miles (220 km)
from the center.

The minimum central pressure estimated by data from NOAA and Air
Force reconnaissance aircraft is 1001 mb (29.56 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...2 to 4 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. 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 by Friday night or Saturday morning, with tropical storm
conditions expected by Friday morning. Hurricane conditions are
possible within the Hurricane Watch area by Friday night or
Saturday morning. Tropical Storm conditions are expected to spread
across the Tropical Storm Warning area starting late tonight, with
tropical storm conditions possible in the Tropical Storm Watch area
by Friday night or Saturday.

TORNADOES: A few tornadoes are possible Friday late morning through
Friday night across southeast Louisiana, far southern Mississippi,
and the Alabama coast.
