Hurricane Katrina Makes Landfall in Louisiana

Katrina came ashore near Buras-Triumph at 11:10 UTC as a high-end Category 3 hurricane with 125 mph winds. Flooding from failures in the federally built levee system put 80% of New Orleans under water.

Katrina is the United States' costliest tropical cyclone, at an estimated $125 billion in damage, and killed 1,392 people — the deadliest American hurricane since the 1928 Okeechobee hurricane. [S]
It peaked as a Category 5 with 175 mph winds and a minimum pressure of 902 mbar early on 28 August, then weakened to Category 3 before landfall near Buras-Triumph at 11:10 UTC on 29 August. [S]
Eighty percent of New Orleans and large areas of neighbouring parishes flooded; an estimated 100,000 to 150,000 people stayed in the city despite mandatory evacuation orders. [S]
The largest loss of life came from engineering flaws in the federally built hurricane protection system, and investigators held the US Army Corps of Engineers responsible for the breached floodwalls. [S]
The National Hurricane Center was praised for forecasts accurate well in advance, while FEMA's response drew criticism that cost its director his job. [S]
The name Katrina was retired by the World Meteorological Organization in April 2006. [S]
