If this doesn't silence the Mayor of New Orleans and the Governor of Louisiana that no one ever warned them about what would happen if cat 4 hurricane hit New Orleans I don't know what would.
Read the full article. It predicts almost exactly what occurred when Katrina hit N.O.

What if Hurricane Ivan Had Not
Missed New Orleans?
Author’s Note: This column was originally intended to be the final disaster in the “Disasters Waiting to Happen” series. As I was developing the hypothetical situation depicting a devastating hurricane striking New Orleans, Louisiana, the disaster waiting to happen threatened to become a reality: Hurricane Ivan, a category 4 hurricane (with 140 mph winds) fluctuating to a category 5 (up to 155 mph winds), was slowly moving directly toward New Orleans. Forecasters were predicting a one-in-four chance that Ivan would remain on this direct path and would be an “extreme storm” at landfall. In reality, the storm veered to the north and made landfall east of Mobile Bay, Alabama, causing devastation and destruction well into the central Gulf shoreline and throughout the Southeast and the Mid-Atlantic states.
What if Ivan Had Hit New Orleans?
New Orleans was spared, this time, but had it not been, Hurricane Ivan would have:
* Pushed a 17-foot storm surge into Lake Pontchartrain;
* Caused the levees between the lake and the city to overtop and fill the city “bowl” with water from lake levee to river levee, in some places as deep as 20 feet;
* Flooded the north shore suburbs of Lake Pontchartrain with waters pushing as much as seven miles inland; and
* Inundated inhabited areas south of the Mississippi River.
Up to 80 percent of the structures in these flooded areas would have been severely damaged from wind and water. The potential for such extensive flooding and the resulting damage is the result of a levee system that is unable to keep up with the increasing flood threats from a rapidly eroding coastline and thus unable to protect the ever-subsiding landscape.
Should this disaster become a reality, it would undoubtedly be one of the greatest disasters, if not the greatest, to hit the United States, with estimated costs exceeding 100 billion dollars. According to the American Red Cross, such an event could be even more devastating than a major earthquake in California. Survivors would have to endure conditions never before experienced in a North American disaster.
