You know, the thing about Katrina was that it essentially missed New Orleans entirely.

The worst case scenario is for the storm to hit to the East, because the rotation would push the water from Lake Ponchatrain into the city. It would have been better off taking a direct hit.

Yep, but also, if say a cat 5 were to hover SE of the river for a day or two and push water into the lake that entire time, and then move up east of the city such that the wind blew from north to south, that would be a doomsday type scenario for the city.

Katrina essentially did that, however im not sure how long it remained in the gulf S or SE of of the river outlet.

That is when I saw it, on saturday afternoon. I admit I wasn’t paying a damn bit of attention to it, then I happned to click of Drudgereport at about 4:00 pm that day, saw where it was and what it was, and I got the FLIP OUT OF DODGE with my dogs, my best friend and my mom as fast ask I could, which was at midnight that evening.

Had I left even 4 hours later, I would not have been able to get two hotel rooms that allowed pets, and I would have been stuck in contra flow traffic for God knows how long.

We were extremely fortunate, God helped us, that’s all I can say.

Isaac came up from the southeast and eventually stalled just south of New Orleans. That cause a westward traveling flow into the lake. There was initially an immense amount of pressure on the northern New Orleans levies. Then after it moved off into the northwest, that pressure subsided. Northward winds pushed the Lake Ponchartrain water up into the northern shore areas that all flooded.

The problem they have to deal with eventually is a flooded Lake Pontchartrain. And they have just started releasing water from a dam up in Mississippi that empties into Lake Pontchartrain. That Lake will rise to near record levels. All the rivers north of that lake are over flood stage. And the Mississippi will be filling up with Isaac water falling up north. Basically a flooding Lake Pontchartrain is what flooded New Orleans last time. The Mississippi levies all held. Heck, if the Mississippi levies failed, New Orleans would have been wiped clean off the map.
