It doesn't have to be a direct hit though, from what I understand the most possible damage will occur if it hits a little SW of the city which could lead to 20 feet of flooding. How close is the storm projected to be to the city?
From what I read if the storm comes close to New Orleans it would be all over for the city, it would just be underwater.
Nah. The storm is strong but it isn't THAT strong. Unless the levees along St. Charles give way, the city will have some flooding, but it will be fine. Being 'under water' for New Orleans will be a little different than what you may expect. Under flooding I've gone outside and seen my car in waist deep water, but that's almost 'accepted normal' for New Orleans.
When you know you're below sea level, there are certain things in the city that you just come to expect and accept. The nightmare scenario that people are talking about with 12-15 feet of standing water in downtown New Orleans would require a complete failure of the levees, the pumps, the canals, the routing walls, etc. That scenario is likely to occur ONLY in the event of a direct strike on the city by a slow moving hurricane that dumps water on the city continuously.
In the scenario that's expected there will be 'feet' of flooding possible, but nothing along the lines of Betsy or Camille.
