SITUATION OVERVIEW
------------------

OVERVIEW...

At 1000 AM CDT, the center of Tropical Storm Barry was
located near latitude 28.2 North, longitude 90.4 West. Barry is
moving toward the west-northwest near 5 mph (7 km/h). A motion
toward the northwest is expected to begin later today, followed by a
turn toward the north Saturday night. On the forecast track, the
center of Barry will approach the central or southeastern coast of
Louisiana 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.

Maximum sustained winds have increased to near 65 mph with higher
gusts.  Additional strengthening is forecast before landfall, and
Barry is expected to be a hurricane when the center reaches the
Louisiana coast. Weakening is expected after Barry moves inland.

POTENTIAL IMPACTS
-----------------

* WIND:
Protect against life-threatening wind having possible extensive
impacts across areas that are mainly across western Terrebonne Parish,
possibly extending into Assumption Parish. Potential impacts in
this area include:
    - Considerable roof damage to sturdy buildings, with some having
      window, door, and garage door failures leading to structural
      damage. Mobile homes severely damaged, with some destroyed.
      Damage accentuated by airborne projectiles. Locations may be
      uninhabitable for weeks.
    - Many large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. Several bridges, causeways, and
      access routes impassable.
    - Large areas with power and communications outages.

Also, protect against dangerous wind having possible significant
impacts across portions of southeast Louisiana and southwest
Mississippi that are generally along and southwest of a line from
Slidell to McComb.

* SURGE:
Protect against life-threatening surge having possible significant
impacts across coastal areas of southeast Louisiana and Mississippi.
Potential impacts in this area include:
    - Areas of inundation with storm surge flooding accentuated by
      waves. Damage to several buildings, mainly near the coast.
    - Sections of near-shore escape routes and secondary roads become
      weakened or washed out, especially in usually vulnerable low
      spots.
    - Major beach erosion with heavy surf breaching dunes. Strong and
      numerous rip currents.
    - Moderate damage to marinas, docks, boardwalks, and piers.
      Several small craft broken away from moorings, especially in
      unprotected anchorages.

Also, protect against locally hazardous surge having possible limited
impacts across the more inland low lying areas of coastal Louisiana,
and along the shores of Lake Maurepas.

Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across portions of southeast Louisiana and southern
Mississippi that are generally along and west of the I-55 corridor, also
including most of the south shore of Lake Pontchartrain.
Potential impacts include:
    - Extreme rainfall flooding may prompt numerous evacuations and
      rescues.
    - Rivers and tributaries may overwhelmingly overflow their banks
      in many places with deep moving water. Small streams, creeks,
      canals, and ditches may become raging rivers. In mountain
      areas, deadly runoff may rage down valleys while increasing
      susceptibility to rockslides and mudslides. Flood control
      systems and barriers may become stressed.
    - Flood waters can enter numerous structures within multiple
      communities, some structures becoming uninhabitable or washed
      away. Numerous places where flood waters may cover escape
      routes. Streets and parking lots become rivers of raging water
      with underpasses submerged. Driving conditions become very
      dangerous. Numerous road and bridge closures with some weakened
      or washed out.

Protect against life-threatening rainfall flooding having possible
limited to extensive impacts across the remainder of southeast
Louisiana and southern Mississippi.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across Southeast Louisiana and South Mississippi. Potential impacts
include:
    - The occurrence of isolated tornadoes can hinder the execution
      of emergency plans during tropical events.
    - A few places may experience tornado damage, along with power
      and communications disruptions.
    - Locations could realize roofs peeled off buildings, chimneys
      toppled, mobile homes pushed off foundations or overturned,
      large tree tops and branches snapped off, shallow-rooted trees
      knocked over, moving vehicles blown off roads, and small boats
      pulled from moorings.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
Listen to local official for recommended
preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.

Do not enter evacuated areas until officials have given the all
clear to return.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Ensure you are in a
safe location before the onset of strong winds or possible flooding.

Keep cell phones well charged. Cell phone chargers for automobiles
can be helpful, but be aware of your risk for deadly carbon monoxide
poisoning if your car is left idling in a garage or other poorly
ventilated area.

Rapidly rising flood waters are deadly. If you are in a flood-prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, turn around don't drown!

Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
