Actually let me walk this back, gonna be a really close call. Also really impressive winds on the 6 PM update 1 Link to comment Share on other sites More sharing options...

Not as intense of course, but it's about as hairy as anything I've seen today. I have not seen that video. I probably just missed the real wild videos. I don't doubt you as the storms presentation is very good. 1 1 Link to comment Share on other sites More sharing options...
jojo762 Posted August 29, 2021 Share Posted August 29, 2021 Well that’s umm… bad with MANY more hours of upstream flow/surge. Does anyone happen to know or have access to data about the levees on each side of the Mississippi? (Eg, how much higher is the levee on the NOLA side vs the eastern side that has been overtopped?)

It is moving due north for sure with an occasional NNE wobble. Going to be VERY close for NOLA proper. Going to be a rough ride for sure in Kenner. Yes…it’s perfectly round and symmetrical now, more so than it was at landfall. Friction with the land tightening things up maybe? Link to comment Share on other sites More sharing options...

jbenedet Posted August 29, 2021 Share Posted August 29, 2021 NOLA aside, there really isn’t a way to implement infrastructure for a track and storm like this in an area broadly at or below sea level. The combination of coastal flooding, river, lake and stream flooding over such a large region for 10+ hours and myriad points of potential failure is just too much to plan for. If there isn’t widespread flooding in Southeast LA all the way up to Lake Maurepas area I’ll be shocked. The rainfall amounts are going to be incredible from IDA as well. Widespread 15”+. Just my 2 cents. 15 Link to comment Share on other sites More sharing options...

Instead I saw 3 roofs blown off, leaning utility poles, and not much else. Maybe it's just solid American construction ha. Concrete buildings simply won't be leveled in a hurricane. I'm sure there will be many many wood buildings that are being leveled that we'll see in the aftermath. 1) people's whose homes/businesses that are being leveled probably don't care to share videos of it on Twitter, and 2) the chasers are generally smart enough to be in areas of concrete buildings rather than wood buildings. 4 Link to comment Share on other sites More sharing options...

MattPetrulli Posted August 29, 2021 Share Posted August 29, 2021 Something that hasn't been talked about much is the lake surge. Gonna continue for a few more hours at least too as the eyewall nears. 2 Link to comment Share on other sites More sharing options...

I am just comparing some of the Youtube videos of past major storms. Maybe no ones position if directly under the worst of the eyewall. Reed Timmers video in Houma definitely has not shown true near white out conditions as we saw many times with Michael. Ida's radar and satellite presentation is so impressive so chasers must be just missing the inner eyewall. How drunk are you ?

Just my 2 cents. This. Ultimately a city built below sea level and South of a gigantic lake is going to near impossible to mitigate given the aforementioned infrastructure from any storm like this. That is why a more coherent and effective evacuation plan is critical, and why this was not better executed Is beyond me. 5 Link to comment Share on other sites More sharing options...
