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

* WIND:
Protect against life-threatening wind having possible devastating
impacts across Lower Acadiana. Potential impacts in this area include:
    - Structural damage to sturdy buildings, some with complete roof
      and wall failures. Complete destruction of mobile homes. Damage
      greatly accentuated by large airborne projectiles. Locations
      may be uninhabitable for weeks or months.
    - Numerous large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Many roads impassable from large debris, and more within urban
      or heavily wooded places. Many bridges and access routes
      impassable.
    - Widespread power and communications outages.

Also, protect against life-threatening wind having possible limited
to extensive impacts across the Atchafalaya Basin.

Elsewhere across Southwest Louisiana and Southeast Texas, little to
no impact is anticipated.

* SURGE:
Protect against life-threatening surge having possible extensive
impacts across Vermilion and Atchafalaya Bays. Potential impacts in
this area include:
    - Large areas of deep inundation with storm surge flooding
      accentuated by battering waves. Structural damage to buildings,
      with several washing away. Damage compounded by floating
      debris. Locations may be uninhabitable for an extended period.
    - Large sections of escape routes and secondary roads washed out
      or severely flooded. Flood control systems and barriers may
      become stressed.
    - Severe beach erosion with significant dune loss.
    - Major damage to marinas, docks, and piers. Many small craft
      broken away from moorings, especially in unprotected anchorages
      with some lifted onshore and stranded.

Also, protect against life-threatening surge having possible
significant impacts across coastal Vermilion Parish.

Also, protect against locally hazardous surge having possible limited
impacts across coastal Cameron Parish.

Elsewhere across Southwest Louisiana and Southeast Texas, little to
no impact is anticipated.

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across Lower Acadiana. 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. 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 South-Central and East-Central
Louisiana.

Elsewhere across Southwest Louisiana and Southeast Texas, little to
no impact is anticipated.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across South-Central and East-Central Louisiana. 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.

Elsewhere across Southwest Louisiana and Southeast Texas, little to
no impact is anticipated.

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

* EVACUATIONS:
WATCH/WARNING PHASE - Listen to local officials for recommended
preparedness actions, including possible evacuation. If ordered to
