Hurricane Katrina devastates Gulf Coast as FEMA and DHS response fails

Hurricane Katrina makes final landfall as a Category 3 storm, causing catastrophic flooding across Louisiana, Mississippi, and Alabama. The storm kills nearly 2,000 people and displaces 1 million residents. FEMA Director Michael Brown and DHS Secretary Michael Chertoff face widespread criticism for inadequate preparation and response. Senate investigations find that DHS and FEMA failed to pre-position supplies and personnel, lacked situational awareness, and suffered organizational failures. Brown admits logistics response was beyond FEMA capacity. Congress later passes the Post-Katrina Emergency Management Reform Act restructuring FEMA within DHS.
