SITUATION OVERVIEW

At 1000 AM CDT, the center of Hurricane Delta was located
along the northern coast of the Yucatan Peninsula. A northwestward
motion is expected over the next 24 hours, followed by a
north-northwestward motion by late Thursday, and a faster northward
to north-northeastward motion Friday and Friday night. On the
forecast track, the center of Delta will move over the southern
Gulf of Mexico this afternoon, be over the southern or central Gulf
of Mexico through Thursday, and approach the northern Gulf coast
within the hurricane watch area on Friday.

Maximum sustained winds are near 105 mph with higher gusts.
Strengthening is forecast when the hurricane moves over the
southern and central Gulf of Mexico through Thursday, and Delta
is expected to become a major hurricane again.  Some weakening is
is forecast as Delta approaches the northern Gulf coast on Friday.

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

* SURGE:
Prepare for life-threatening surge having possible devastating
impacts across coastal 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, prepare for life-threatening surge having possible significant
to extensive impacts across coastal southwest Louisiana.

Also, prepare for 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:
Prepare for life-threatening wind having possible devastating impacts
across southwest and south 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, prepare for life-threatening wind having possible significant
to extensive impacts across southeast Texas and central Louisiana.

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across Louisiana. Potential impacts
include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - Rivers and tributaries may quickly become swollen with swifter
      currents and overspill their banks in a few places, especially
      in usually vulnerable spots. Small streams, creeks, canals, and
      ditches overflow.
    - Flood waters can enter some structures or weaken foundations.
      Several places may experience expanded areas of rapid
      inundation at underpasses, low-lying spots, and poor drainage
      areas. Some streets and parking lots take on moving water as
      storm drains and retention ponds overflow. Driving conditions
      become hazardous. Some road and bridge closures.

Prepare for locally hazardous rainfall flooding having possible
limited impacts across southeast Texas.

* TORNADOES:
Prepare for 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:

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

For those not under evacuation orders, assess the risk from wind,
falling trees, and flooding at your location. If you decide to move,
relocate to a safer location nearby. If you do not relocate, help
keep roadways open for those under evacuation orders.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.

When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.

If in a place that is vulnerable to high wind, such as near large
trees, a manufactured home, or on a boat, plan to move to safe shelter.

If you live in a place particularly vulnerable to flooding, such as
near the Gulf or a large inland lake, in a low-lying or poor
drainage area, or near an already swollen river, plan to move to
safe shelter on higher ground.

Always heed the advice of local officials and comply with orders that
are issued. Do not needlessly jeopardize your life or the lives of
others.

When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.

Be sure to let friends and family members know of your intentions for
weathering the storm and your whereabouts. Have someone located away
from the threatened area serve as your point of contact. Share vital
contact information with others. Keep cell phones handy and charged.

Check on those who may not be fully aware of the situation or who are
unable to make personal preparations.

If you are a visitor, know the name of the county or parish in which
you are located and where it is relative to current watches and
warnings. If staying at a hotel, ask the management staff about their
onsite disaster plan. Listen for evacuation orders, especially
pertaining to area visitors.

Closely monitor weather.gov, NOAA Weather Radio and local news
outlets for official storm information. Listen for possible changes
to the forecast.

There is a threat from tornadoes with this storm. Have multiple ways
to receive Tornado Warnings. Be ready to shelter quickly.
