In the book “rising tide” this is the close to the same weather pattern they had in 1927
Wet fall all the way from gulf up to Minnesota
Wet spring in same areas with plenty of snowfall
Hopefully when the snow starts to melt the Tennessee and Ohio Valleys will go through a dry period

Looks like crest in BR got bumped up 44’.

Hypothetically if the levee broke without warning in BR, would it be the worst natural disaster in US history? You'd have 300,000 people sitting on their roofs.

I mean yeah, a surprise 10' flood would be bad for Baton Rouge.

There’s a lot of us in BR that wouldn’t flood.

300,000 people? It would no doubt be a disaster but you are overestimating the inundation.

They would open Morganza and blow levees up north flooding 100ks of acres of farm land before BR / NO levees get topped. If that ain’t enough then ORCS is, as many believe, vulnerable.
Are you referring to Bird Point floodway protecting Cairo?

Thing about that is the water would run back into the river downstream. It would take the pressure off Cairo (which is a ghost town now, btw. there's nothing to protect any more). But it wouldn't affect the downstream water levels.

That's kinda impressive. Know what those two red spots are in the Southern part of this scan?
They're the gypstacks in between Geismar and St. Gabriel. The big red blotch is the big one at 30 and 3115.

And it looks like they bumped up crest date a few days
Posted on 3/5/19 at 6:09 pm to LSUsmartass
What is crest date as of now?

What’s that rainbow river picture I’m looking at?
Posted on 3/5/19 at 7:12 pm to FeauxPaw
Very cool and helpful map. Can you post the next block over over, E. of -90.80?
What would the impact be there on watersheds below 1-12? Especially Tangipahoa and Tchefuncte Rvers?

That’s topography of BR area
Posted on 3/5/19 at 7:31 pm to Jim Rockford
It would be pretty bad. My guess is that it would get pretty close to Highland Rd

It went to 45' back in 2011. That was the highest it's been since 1945.
47' was the great flood of 1927, but obviously that was before the new infrastructure was put in place.

Bump for the latest forecast bumping it up to 44'.


Posted on 3/6/19 at 8:57 am to TDsngumbo
GFS shows about 50/50 below freezing temps and well above freezing temps for the central/northern plains as well as the Ohio River valley over the next two weeks. Combined with more rain, the snow will start to melt then refreeze then melt again.
