SITUATION OVERVIEW
------------------
At 700 PM CDT, the center of Tropical Storm Cristobal was located near
latitude 29.6 North, longitude 89.8 West. Cristobal is moving toward
the north near 7 mph. A turn toward the north-northwest is expected
later this evening and tonight, followed by a northward motion Monday
night and Tuesday.

Gusty winds will continue over the eastern coastal waters this evening
as Tropical Storm Cristobal continues to move inland along the southeast
Louisiana coast. With the storm forecast to remain east of the area, a
predominately offshore flow will prevail tonight. A moderate onshore
flow will develop over the coastal waters on Monday.

There is the potential for heavy rainfall that may lead to flash flooding
over portions of southwest, south central and central Louisiana on Monday
with potential rainbands around Cristobal.

Coastal flooding from storm surge of 1 to 3 feet above the ground will
also be possible by tonight 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 mainly on
Monday afternoon and evening with some of the rainbands around
Cristobal.

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

* WIND:
Prepare for hazardous wind having possible limited impacts across
SOUTH CENTRAL LOUISIANA. Potential impacts in this area 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:
Prepare for locally hazardous surge having possible limited impacts
across COASTAL SOUTH CENTRAL LOUISIANA. 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.

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across CENTRAL AND SOUTH CENTRAL 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 SOUTHWEST LOUISIANA.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across
SOUTH CENTRAL, AND SOUTHWEST LOUISIANA AND SOUTHEAST TEXAS. 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.
