Gulf Coast — High Risk Zone

Hurricane Preparedness in Louisiana

Louisiana is one of the most hurricane-vulnerable states in the nation. With a coastline shaped by the Mississippi River delta, extensive low-lying marshland, and major population centers like New Orleans sitting below sea level, the storm surge risk here is extraordinary. Residents must prepare before storm season — not after a storm is named.

⚠ Storm Surge Warning

Storm surge — not wind — is the leading cause of hurricane deaths in Louisiana. Surge can exceed 15–20 feet in some coastal parishes during a major hurricane. Know your parish evacuation zone before the season starts.

Major Hurricanes Affecting Louisiana

Louisiana has endured some of the most destructive hurricanes in U.S. history, including Hurricane Katrina (2005), Hurricane Rita (2005), Hurricane Gustav (2008), Hurricane Ike (2008), Hurricane Laura (2020), and Hurricane Ida (2021). Ida caused over $75 billion in damage. Laura made landfall near Lake Charles as a Category 4 with a catastrophic storm surge.

⚡ Contraflow Operations

Louisiana activates contraflow (reverse lane) operations on I-10, I-12, and I-55 when major evacuations are ordered. Monitor DOTD and local news for contraflow activation. Leave early — contraflow does not start immediately and roads fill fast.

Louisiana Hurricane FAQ

Louisiana uses a parish-based evacuation zone system with zones A through D based on storm surge risk. Zone A has the highest risk and evacuates first. Contact your parish emergency management office or visit gohsep.la.gov for your specific zone.
Possibly — it depends on your zone and location. In Louisiana, storm surge from even a Category 1 or 2 storm can be life-threatening in low-lying coastal areas. Always follow parish-level evacuation orders. Don't base your decision solely on category.
Contraflow reverses the lanes of major interstates so that all lanes carry outbound traffic during large evacuations. Louisiana activates contraflow on I-10, I-12, and I-55 when ordered. Monitor DOTD and local emergency broadcasts for activation status.
