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

Hurricane Delta has made its awaited north turn overnight, and will
begin to turn more to the northeast in the coming hours. As of 10 AM
CDT, Hurricane Delta has maximum sustained winds near 115 mph with
higher gusts, and as such Delta remains a category 3 major hurricane.
Cooler coastal waters and wind shear are expected to result in a
weakening trend as Delta moves closer to landfall, with landfall
expected this evening along the eastern Cameron coastline. Regardless
of any weakening trend, Hurricane Delta is expected to remain a large
and dangerous storm. Conditions will continue to deteriorate as the
day progresses, with life threatening storm surge expected in
vulnerable coastal areas. Winds are expected to increase to hurricane
strength in portions of southwest, south central, and central
Louisiana, with tropical storm force winds elsewhere. In addition,
heavy rain will result in a significant flash flood and river flood
threat as Delta moves ashore.

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

* SURGE:
Protect against life-threatening surge having possible devastating
impacts across coastal southwest and south central Louisiana.
Potential impacts in this area include:
    - Widespread deep inundation, with storm surge flooding greatly
      accentuated by powerful battering waves. Structural damage to
      buildings, with many washing away. Damage greatly compounded
      from considerable floating debris. Locations may be
      uninhabitable for an extended period.
    - Escape routes and secondary roads washed out or severely
      flooded. Flood control systems and barriers may become stressed
      or overtopped.
    - Extreme beach erosion. New shoreline cuts possible.
    - Massive damage to marinas, docks, and piers. Numerous small
      craft broken away from moorings with many lifted onshore and
      stranded.

Also, protect against life-threatening surge having possible
significant to extensive impacts across coastal southwest Louisiana.

Also, protect against locally hazardous surge having possible limited
impacts across coastal southeast Texas.

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

* WIND:
Protect against life-threatening wind having possible devastating
impacts across southwest, south central, and central Louisiana.
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 central and south central Louisiana, as
well as southeast Texas.

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across southwest and central Louisiana. 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
significant to extensive impacts across southeast Texas.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across south 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:
If evacuating, leave with a destination in mind
and allow extra time to get there. Take your emergency supplies kit.
Gas up your vehicle ahead of time.

If evacuating, follow designated evacuation routes. Seek
traffic information on roadway signs, the radio, and
from official sources.

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

* OTHER PREPAREDNESS INFORMATION:
Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.

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.

It is important to remain calm, informed, and focused during an
emergency. Be patient and helpful with those you encounter.

Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the local authorities.

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.
