This is a NEW disaster
17th Street Canal -- two block breach.
oh this is not good and there will be more breeches
This is almost the worst case. The flooding will fill the bowl of the main part of the city. It is just as if the storm surge had overtopped the levee, but will take a bit longer. If they can't plug that leak, it will flood to sea level, 8-12 deep in much of the city. The FQ and Superdome are above sea level, but the flooding just got much worse.
