the MS river is very high due to heavy rain the past 12 months , 16 feet At New Orleans,
the levees protect it to 20 feet
most of the time when tropical systems hit the river is only 4-8 feet
any surge will go up the MS river.... extreme example: Katrina raised it form 4 feet to 17 feet
but since the river s so high the downward momentum is also higher then a lower river level and the same surge at 3 feet level won’t be as high as 16 feet..
This is being discussed at various places and there appears o be no otvery little model data for such a scenario
NOLA already has tornados spawning.
