"The truth is, New Orleans, if hit, will flood. How badly depends on the hurricane. In his book The Storm (Viking; 320 pages), out this week, Louisiana State University researcher Ivor van Heerden argues that Katrina wasn't the mythical Big One, a frightening conclusion for a city entering a new hurricane season.
The storm made landfall east of New Orleans as a fast-moving Category 3, he notes, but the winds that lashed the city—weakened by wetlands and miles of subdivisions—registered only as a Category 1. Van Heerden, deputy director of the LSU Hurricane Center in Baton Rouge, warns that a slow-moving Category 3 hurricane passing west of the city would flood levee to levee—including the historic French Quarter, which was spared last time—even without the embankments breaking.
Another man-made disaster, like the levee breaches after Katrina, could turn New Orleans into a "Cajun Atlantis," Van Heerden fears, crippling the coastal economy along with it. "The uneasiness is not just in New Orleans. It's right across the southern part of the state," he says.
On a tour of the city's earthen and floodwall defenses last week, Van Heerden said levee problems could endanger areas that were not flooded after Katrina, including the west bank of the Mississippi and the western suburbs of New Orleans, most notably near the airport, an area crucial to every evacuation plan."
