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

At 400 PM CDT, the center of Tropical Storm Cristobal was located near
latitude 25.2 North, longitude 90.2 West. Cristobal is moving toward
the north near 12 mph and this general motion is expected to continue
for the next day or so, followed by a gradual turn toward the
north-northwest. On the forecast track, the center of Cristobal will
move northward over the central Gulf of Mexico tonight, and will be
near the northern Gulf of Mexico coast on Sunday. Cristobal's center
is then forecast to move inland across Louisiana late Sunday through
Monday morning, and northward across Arkansas and Missouri Monday
afternoon into Tuesday.

Tropical storm force winds are likely within the Tropical Storm
Warning over the coastal waters beginning tonight and likely within
the Tropical Storm Warning along the coast early Sunday.

There is the potential for heavy rainfall that may lead to flash
flooding over portions of south central Louisiana late Sunday 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 Sunday into early Monday, mainly around the
Vermilion and Atchafalaya Bays when onshore flow returns.

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

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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across LOWER ATCHAFALAYA BASIN. 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.

Protect against locally hazardous rainfall flooding having possible
limited impacts across SOUTH CENTRAL AND EAST CENTRAL LOUISIANA.

* SURGE:
Protect against locally hazardous surge having possible limited
impacts across LOCATIONS AROUND THE VERMILION AND ATCHAFALAYA BAYS.
Potential impacts in this area 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.

* WIND:
Protect against hazardous wind having possible limited impacts across
SOUTH CENTRAL LOUISIANA. Potential 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.

* 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:

preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.
