You are at risk for all hurricanes especially if:

  •   You live outside of levee protection.
  •   You live in a mobile home or recreational vehicle.
  •   You live in a low-lying inland area or on the coast.
  •   Everyone is especially at risk if a hurricane is category 3(slow) or, 4, and 5(slow/fast).

Evacuation Considerations

  •   Has your area been advised to evacuate by local and/or State officials via   radio and television?
  •   When recommended to evacuate will Public Shelters be available locally or outside the Jefferson Parish area?
  •   Have you planned for your destination out of the risk area and studied what routes will be available?


Hurricane Evacuation Guidelines

The overall strategy of all Southeast Louisiana Parishes when confronted with the possibility of a catastrophic hurricane is to evacuate as much of the risk population as possible from the path of the storm. Evacuees would be recommended to relocate to a place of relative safety outside the projected high water mark of the storm surge flooding and hurricane force winds. Sophisticated computer models of hurricane storm surge effects in Southeast Louisiana indicate that the hurricane protection levees built to protect life and property would be overtopped from the storm surge generated by a direct strike of a major hurricane resulting in widespread flooding.

The Greater New Orleans area also represents a difficult evacuation problem due to a large population attempting to use an inadequate road network that is limited and susceptible to flooding.

An evacuation notice will be issued when a hurricane is forecasted to present a danger to Jefferson Parish. The timing of this notice will depend on the probability of landfall in this area and the severity and forward speed of the storm.

The public is encouraged to act in their best interest and voluntarily evacuate the risk area when advised to do so.

If you plan to evacuate, leave as early as possible before tropical storm force winds and storm surge cause road closures. Leaving early will also help you avoid possible traffic jams and road restrictions that will be in place after contraflow is implemented.

State Police Phased Evacuation

During a threat of a hurricane, a phased evacuation will be based on geographic location and time in which tropical storm winds are forecasted to reach the affected areas.

Phase I - 50 Hours before onset of tropical storm winds. Includes areas south of the Intracoastal Waterway. These areas are outside any levee protection system and are vulnerable to Category 1 and 2 storms. During Phase 1, there are no route restrictions.

Phase II - 40 Hours before onset of tropical storm winds. Includes areas south of the Mississippi River which are levee protected but remain vulnerable to Category 2 or higher storms. During Phase II, there are no route restrictions.

Phase III - 30 Hours before onset of tropical storm winds. Includes areas on the East Bank of the Mississippi in the New Orleans Metropolitan Area which are within the levee protection system but remain vulnerable to a slow-moving Category 3 or any Category 4 or 5 storm. During Phase III, certain routes will be directed and the Contraflow Plan implemented.
