Monday, August 29
- Katrina makes landfall near Buras, Louisiana, on the west bank of the Mississippi, as a strong Category 3 storm. Levees in St. Bernard Parish begin failing, and levees around the Lower Ninth Ward follow. Levees around the Industrial Canal are first overtopped, then breached, leading to catastrophic flooding in the Lower Ninth. Breaching occurs in the London Avenue and 17th Street Canals (two drainage canals that empty into Lake Pontchartrain), leading to serious flooding of the Orleans Metro Bowl. The Army Corps confirms breaches, but that information does not make it to first responders or local emergency staff. Two-thirds of drowning deaths occur after the drainage-canal breaches.
Tuesday, August 30
- The water is still rising as the New Orleans bowl fills. Officials deny alarm and don’t appear aware of the continued flooding. DHS declares Katrina an “incident of national significance,” triggering the first use of the National Response Plan created after 9/11 to create a single federal command unit for military and civilian assets. Governor Blanco orders complete evacuation of the city. Media coverage describes mass “looting” and “lawlessness.”
Wednesday, August 31

Thousands of residents escaping flooding accumulate at the nearby convention center, an unofficial evacuation center without provisions. Joint Task Force Katrina is established, with Army Lieutenant Governor Russel Honoré as commander. Air Force One flies low over New Orleans, and President Bush is photographed looking out at the devastated city.
Thursday, September 1
- News coverage continues of several bodies in and around the convention center. In an NPR interview, DHS Secretary Michael Chertoff says he is unaware of evacuees at the center. FEMA Director Michael Brown says the government only just became aware that the center was being used as a shelter, despite regular media coverage. Police Chief Eddie Compass describes rapes and beatings, adding to rumors of widespread crime.
