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


At 7 AM CDT, the center of Tropical Storm Cristobal continues to move
north toward the Louisiana coast, and is expected to move ashore south
of Houma later this afternoon. Cristobal's center is then forecast to
track inland across southern Louisiana east of the Atchafalaya River
tonight and into northeast Louisiana by Monday morning.

Tropical storm force winds are occurring within the Tropical Storm
Warning over the coastal waters, and are likely within
the Tropical Storm Warning along the coast later this morning.

There is the potential for heavy rainfall that may lead to flash
flooding over portions of south central Louisiana late tonight into
Monday near the track of Cristobal.

Coastal flooding from storm surge of 1 to 3 feet above the ground will
also be possible by late today into early Monday, mainly around the
Vermilion and Atchafalaya Bays when onshore flow returns.

There is a low end potential for a few isolated tornadoes as early as
this afternoon in lower Acadiana with some of the leading outer
bands.

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

* WIND:
Potential impacts from the main wind event are now unfolding across
coastal south central Louisiana. Remain well sheltered from hazardous
wind having possible 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 SOUTHWEST LOUISIANA AND SOUTHEAST TEXAS, little to
no impact is anticipated.

* SURGE:
Potential impacts from the main surge event are now unfolding across
coastal south central Louisiana. Remain well away from locally hazardous
surge having possible limited impacts. If realized, these impacts
include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots, or in areas
      farther inland along rivers and bayous that drain into the Gulf.
    - Sections of roads and parking lots near bodies of water may
      become overspread with surge water. Driving conditions
      dangerous in places where surge water covers the road.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly
      in usually vulnerable locations. Strong rip currents.
    - Minor to locally moderate damage to marinas, docks, and piers.
      A few small craft broken away from moorings.

Elsewhere across SOUTHWEST LOUISIANA AND SOUTHEAST TEXAS, little to
no impact is anticipated.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
central and south central Louisiana. Remain well guarded against dangerous
flood waters having possible significant impacts.  If realized, these
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.

Elsewhere across SOUTHWEST LOUISIANA AND SOUTHEAST TEXAS, little to
no impact is anticipated.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across SOUTHWEST
LOUISIANA AND SOUTHEAST TEXAS. 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.

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

* EVACUATIONS:

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 stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a
battery-powered radio, charged cell phone and flashlight handy.
