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

At 9 pm CDT...Hurricane Delta continues to penetrate inland over
southwest and south-central Louisiana after having made landfall
near Creole, LA around 6 pm this evening. Tropical storm force winds
and higher gusts near hurricane force are buffeting the area this
evening. These stronger winds will slowly lessen later tonight as
Delta weakens to tropical storm status.

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

* WIND:
Potential impacts from the main wind event are now unfolding across
east-central and southeast Louisiana and expanding into southwest
Mississippi. Remain well sheltered from hazardous
wind having additional limited impacts. If realized,
these impacts include:
    - Damage to porches, awnings, carports, sheds, and unanchored
      mobile homes. Unsecured lightweight objects blown about.
    - Many large tree limbs broken off. A few trees snapped or
      uprooted, but with greater numbers in places where trees are
      shallow rooted. Some fences and roadway signs blown over.
    - A few roads impassable from debris, particularly within urban
      or heavily wooded places. Hazardous driving conditions on
      bridges and other elevated roadways.
    - Scattered power and communications outages.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
southwest Mississippi and in portions of southeast Louisiana.
Remain well guarded against life-threatening flood waters having
possible extensive impacts. If realized, these impacts include:
    - Major rainfall flooding may prompt many evacuations and rescues.
    - Rivers and tributaries may rapidly overflow their banks in
      multiple places. Small streams, creeks, canals, and ditches may
      become dangerous rivers. Flood control systems and barriers may
      become stressed.
    - Flood waters can enter many structures within multiple
      communities, some structures becoming uninhabitable or washed
      away. Many places where flood waters may cover escape routes.
      Streets and parking lots become rivers of moving water with
      underpasses submerged. Driving conditions become dangerous.
      Many road and bridge closures with some weakened or washed out.

Potential impacts from the flooding rain are still possible elsewhere
in southern Louisiana. Remain well guarded against dangerous
flood waters having possible limited to significant impacts.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across Southeast
Louisiana and South Mississippi. Remain well braced against a tornado
event having possible limited impacts. If
realized, these 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.

* SURGE:
Potential impacts from the main surge event are now unfolding across
the central Louisiana coast. Remain well away from life-threatening
surge having possible significant impacts. If
realized, these impacts 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.

Potential impacts from the main surge event are also now unfolding
across the eastern Louisiana waters including the tidal lakes. Remain
well away from locally hazardous surge having possible limited impacts.

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

PRECAUTIONARY/PREPAREDNESS ACTIONS
