Is anyone familiar with the infrastructure of I-10 and 90 with regards to the Atchafalaya? Worst case scenario and the River shifts west, would any bridges be in danger of failure?

Yeah. Should be.

Record snow in the Rockies this year. Though most of that flows west of continental divide
Quite a bit will flow down the Arkansas and Platte but it will end up in reservoirs before it gets to the Mississip.

Most of them and several pipelines.

The total qpf up to March 17 didn't look overly terrible. 2-3 inches in the Tennessee Valley, 1-2 in the Ohio Valley, and less than that in the upper Mississippi.
Too far out to trust. If you get a couple of lows following that path more should end up in the Ohio and Tennessee. The WPC is getting pretty good out to a week on the qpf.
Pretty much anything in the upper Mississippi is likely to be snow for the entire period. It'll be coming later.
It's the right now that's going to be helpful. This break in the pattern will have it dropping up there before this potential rain gets in the system.

I was afraid of that.

Lots of snow in the Missouri watershed.

Yeah that was the one positive. The systems are moving pretty quick

More wishcasting going on ITT than a hurricane one. People can start panicking when the coe start dynamiting levee upstream to try and save the orcs.

That kind of thinking ignores the danger posed by the continued silting of the river immediately south of ORCS. The flows could be withing Design Flood, but if there isnt enough area to hold than flow the river going to run higher than designed, and you have a problem.
For example, in 2011 Morganza didnt open due to the flow, it was due to the river height. That should tell you that something is going on with the river bed elevations.

The demise of Ur was perhaps owing to drought, changing river patterns, and the silting of the outlet to the Persian Gulf.

Looks like it’s coming down pretty good in Memphis area, has it crested in that area yet?
I drove to Gatlinburg yesterday, the rivers I crossed all looked tapped out on capacity. First time I’ve seen flooded stands of pine.

The Atchafalaya Expressway wasn't designed for the flow of the Mississippi river (or the debris that would be striking the pilings). It would sustain critical damage and failures.
Somewhere out there is a report that was done in the early 80s (or late 70s) by LSU estimating the impacts of an ORCS failure and the rerouting of the Mississippi down the Atchafalaya under the same conditions of the 73 flood. It's Roland Emmerich's wet dream.

Should just let it happen. Would get billions and billions from feds to rebuild infrastructure.
Only way we getting a loop baws.

True but would still drip down to a loop and 6 lane Basin Bridge.

The post ORCS failure LA frightens me more than the failure itself. Talk about a cluster frick trying to get shite done.

Don't know if you saw that old video of the building of the Atchafalaya Expressway, but they did that shite in 2 years.
With OSHA and the environmental impact studies, it would be 10 years at a minimum before I-10 was rebuilt.
President could declare national emergency to bypass all that (which is what Trump should do about the I-10 bridge/loop issue)
