inland.

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

* SURGE:
Prepare for life-threatening surge having possible significant
impacts across VERMILION BAY AND ATCHAFALAYA BAY. Potential impacts in
this area include:
    - Areas of inundation with storm surge flooding accentuated by
      waves. Damage to non-elevated structures is possible.
    - Sections of 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, and piers. Several small
      craft broken away from moorings, especially in unprotected
      anchorages.


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

* WIND:
Prepare for dangerous wind having possible significant impacts across
SOUTHWEST AND SOUTH CENTRAL LOUISIANA. Potential impacts in this area
include:
    - Some damage to roofing and siding materials, along with damage
      to porches, awnings, carports, and sheds. A few buildings
      experiencing window, door, and garage door failures. Mobile
      homes damaged, especially if unanchored. Unsecured lightweight
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater
      numbers in places where trees are shallow rooted. Several
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges and access routes
      impassable.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines.

* FLOODING RAIN:
Prepare for locally hazardous rainfall flooding having possible
limited impacts across SOUTHWEST LOUISIANA and SOUTHEAST TEXAS.
Potential impacts include:
    - Localized rainfall flooding may prompt a few evacuations.
    - Rivers and tributaries may quickly rise with swifter currents.
      Small streams, creeks, canals, and ditches may become swollen
      and overflow in spots.
    - Flood waters can enter a few structures, especially in usually
      vulnerable spots. A few places where rapid ponding of water
      occurs at underpasses, low-lying spots, and poor drainage
      areas. Several storm drains and retention ponds become
      near-full and begin to overflow. Some brief road and bridge
      closures.

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

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