Hurricane Katrina: A look back at the humanitarian crisis

Many of the over million residents who left the Gulf Coast who left because of Hurricane Katrina never returned. For those who stayed, many had to endure years of hardships.

THE TAKEAWAY

• Aug. 29, 2026 marks the 21st anniversary of Hurricane Katrina's landfall in Louisiana.
• Adjusted for inflation, NOAA estimates the 2024 value of damage caused by the storm to be north of $201 billion.
• Within 48 hours of landfall, authorities estimated that 80% of New Orleans was underwater.

NEW ORLEANS – Twenty-one years ago, Hurricane Katrina roared ashore along the Gulf Coast, leaving an indelible mark as one of the deadliest and most destructive disasters in U.S. history.

The cyclone first developed on Aug. 23, 2005, as a tropical depression over the southeastern Bahamas and, within a day, strengthened into Tropical Storm Katrina before moving toward Florida. 

Katrina quickly organized, fueled by the warm waters of the Gulf, and made landfall near the Miami-Dade and Broward County line as a Category 1 hurricane with winds of 80 mph.

The storm stayed compact as it traveled across Florida, and once it reached the warm waters of the Gulf, leading to the explosive intensification of one of the worst hurricanes to ever impact the U.S.

Within 72 hours, Katrina became a Category 5 hurricane with peak sustained winds of 175 mph and a central pressure of 902 millibars.

Katrina later weakened to a Category 3 hurricane before making landfall at 6:10 a.m. local time on Aug. 29, 2005, near the mouth of the Mississippi River near Buras, Louisiana. 

The storm carved a deadly path across Louisiana, Mississippi, Alabama and the Florida Panhandle, killing more than 1,000 people and causing over $100 billion in damage.

The storm’s death toll also ranks among the 10 deadliest hurricanes in U.S. history. 

While the official count stands at 1,392, discrepancies in medical records and incomplete reporting have led to debate over the exact number.

The world’s attention turned to New Orleans, where flooding reached levels unseen in the city’s long history.

The combination of rainfall and surge overwhelmed levee systems and within 48 hours of landfall, authorities estimated that 80% of the Big Easy was underwater, displacing hundreds of thousands of residents.

"It was frightening beyond words," FOX Weather Hurricane Specialist Bryan Norcross recounted. "A meteorologist at the National Weather Service in New Orleans wrote this epic warning that neighborhoods are going to be unlivable for a long period of time."

Hurricane Katrina’s legacy is measured not only in the lives lost and neighborhoods destroyed, but in how it reshaped disaster preparedness, and flood protection.
