Bull...it was plenty forseen. They were calling this the big one on Saturday. The 48hr forecast had it making landfall as a 125kt hurricane and was right on track. I am a meteorologist...it was FORESEEN!
And this from the NHC well before landfall...
COASTAL STORM SURGE FLOODING OF 15 TO 20 FEET ABOVE NORMAL TIDE LEVELS...LOCALLY AS HIGH AS 25 FEET ALONG WITH LARGE AND DANGEROUS BATTERING WAVES...CAN BE EXPECTED NEAR AND TO THE EAST OF WHERE THE CENTER MAKES LANDFALL.
So...who said it was not forseen? This was totally forseen and was known to be the big one. The only people who did not "forsee" it were people who were not paying attention.
I've already corrected myself on that statement. Again, I stand corrected. What I meant was through the warnings, YES PEOPLE SHOULD HAVE GOTTEN OUT..those that stayed either couldn't get out for unknown reasons, or WANTED to stay..again, the day AFTER the storm it was reported that N.O. had dodged the bullet when the hurricane turned slightly NE and the weaker wall would hit. The levies broke a day or two after the hurricane, THAT is what was unexpected..
