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

At 1 AM CDT, Tropical Storm Harvey is moving toward the northeast near
7 mph. Harvey is expected to move inland over the northwestern Gulf
coast early this morning. The main impact across southeast Louisiana
and south Mississippi will be isolated tornadoes, heavy rain and the
potential for flash flooding, minor coastal flooding outside of the
hurricane protection levee system, and gusty winds.

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

* TORNADOES:
Protect against a tornado event having possible limited impacts
across Southeast Louisiana and South Mississippi. 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.

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across the River Parishes and Bayou Region.
Potential impacts include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - 2 to 4 inches of rainfall will be possible.
    - 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,
      bayous, 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.

* SURGE:
Protect against locally hazardous surge having possible limited
impacts across immediate coastal areas of Terrebonne, Lafourche, and
Jefferson Parishes, including the city of Grand Isle. Potential impacts in
this area include:
    - 1 to 2 feet with isolated areas of 3 feet of storm surge inundation
      will be possible outside of levee protected areas.
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots, or in areas
      farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots 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, boardwalks,
      and piers. A few small craft broken away from moorings.

* WIND:
Protect against hazardous wind having possible limited impacts across
portions of the River Parishes and Bayou Region. 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.

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


* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and take necessary
actions to secure your home or business. Deliberate efforts should be
underway to protect life and property. Ensure that your Emergency
