New Orleans is the most hurricane-vulnerable major city in the United States. Most of the city sits below sea level — in some areas 8 to 10 feet below — protected only by an elaborate system of levees and floodwalls. Hurricane Katrina in 2005 caused catastrophic levee failures that flooded 80% of the city, killed over 1,800 people, and caused $170 billion in damage — the costliest natural disaster in US history. Hurricane Ida in 2021 tested the post-Katrina flood protection system to its limits as a Category 4.

// Preparedness Recommendations

  • Evacuation routes inland should be identified in advance.
  • Store at least 72 hours of food and water.
  • Elevate critical belongings above flood level.
  • Have backup power ready in case of grid failure.

// Recommended Supplies

Essential gear for power outages, severe weather, and emergency situations in your area.
