Today marks the five-year anniversary of Hurricane Katrina. Katrina formed over the Bahamas as a category one storm but grew into a category three before making landfall on the Gulf Coast. The storm caused excessive damage to the Gulf Coast but New Orleans was hit the hardest. The city’s levee system failed, causing extensive flooding and citywide devastation and chaos. The flood water then lingered for weeks, and a jaw-dropping 1,800 people lost their lives in the aftermath of the storm, while massive portions of New Orleans, Mississippi and other coastal areas were destroyed. The storm was the costliest in American history and the sixth deadliest; the total property damage was estimated at over 81 billion dollars.
