20 years after Katrina, New Orleans remembers
Next month marks the 20th anniversary of one of the most devastating natural disasters in US history: Hurricane Katrina, a Category 3 storm that made landfall on August 29, 2005. The storm itself was bad enough, but the resulting surge of water caused havoc for New Orleans in particular when the city's protective levees failed, flooding much of New Orleans and killing 1,392 people. National Geographic is marking the occasion with a new documentary series: Hurricane Katrina: Race Against Time. T
