It's only a matter of time before South Louisiana takes a direct hit from a major hurricane. Billions have been spent to protect us, but we grow more vulnerable every day.
Five-Part Series
It's a matter of when, not if. Eventually a major hurricane will hit New Orleans head on, instead of being just a close call. It's happened before and it'll happen again.

"A catastrophic hurricane represents 10 or 15 atomic bombs in terms of the energy it releases," said Joseph Suhayda, a Louisiana State University engineer who is studying ways to limit hurricane damage in the New Orleans area. "Think about it. New York lost two big buildings. Multiply that by 10 or 20 or 30 in the area impacted and the people lost, and we know what could happen."
Hundreds of thousands would be left homeless, and it would take months to dry out the area and begin to make it livable. But there wouldn't be much for residents to come home to. The local economy would be in ruins.
The scene has been played out for years in computer models and emergency-operations simulations. Officials at the local, state and national level are convinced the risk is genuine and are devising plans for alleviating the aftermath of a disaster that could leave the city uninhabitable for six months or more. The Army Corps of Engineers has begun a study to see whether the levees should be raised to counter the threat. But officials say that right now, nothing can stop "the big one."
Like coastal Bangladesh, where typhoons killed 100,000 and 300,000 villagers, respectively, in two horrific storms in 1970 and 1991, the New Orleans area lies in a low, flat coastal area. Unlike Bangladesh, New Orleans has hurricane levees that create a bowl with the bottom dipping lower than the bottom of Lake Pontchartrain. Though providing protection from weaker storms, the levees also would trap any water that gets inside -- by breach, overtopping or torrential downpour -- in a catastrophic storm.
