ATL: IDA - Remnants - Discussion

[chaser1]

Have there been any news, weather service, or government graphics posted that provide a visual of those areas undergoing the worse flooding? I'm trying to get an idea if any of the flooding is within the levee dike system due to some type of breach, or if this is primarily storm surge related spilling out from Lake P north and west of those areas guarded by the levees in place.

I haven’t seen any graphics but this list of articles mentions two levee failures with areas affected https://www.nbcnews.com/news/us-news/li ... BlogHeader

I would like to personally apologize for sharing some unverified information which in hindsight I can see that I should have vetted or made mention of its credibility at the time.

Also going to say that earlier I had mentioned that maybe a well timed ERC could help level off/knock down intensity right at landfall however it is clear in this case that almost the exact opposite has occurred and that did indeed turn into a much worse situation. This shoe tastes horrible

My thoughts go out to all those affected

“ Lafitte-area levees overtopped, not failed: Jefferson Parish president

The levees in the area of Lafitte, 20 miles south of New Orleans, did not breach as Hurricane Ida hit overnight despite earlier reports, Jefferson Parish president said.

Cynthia Lee Sheng told the "TODAY" show Monday the levees were overtopped, but did not fail. It was earlier reported by the National Weather Service that the levees in the area may have breached, putting over 200 people were in "imminent danger.”

"There was no structural failure of the levees, it's just that the water was higher than the levee that was built," Sheng said. ”

Just saw the President of Jefferson Parish, the county that Grand Isle belongs to, say that they yet have to have contact with the approximate 40 people that stayed behind.
Very little cell service if any in around Nola, can't get in touch with many of my friends and family in the city. About 95% of SE LA has no power this morning.

Looking around in the internet this morning, many are saying how the highest winds reported at N.O. Int'l (MSY) was 90 mph, but there was a period of two hours that the reports coming out of MSY did not report wind speeds, in the moment they were reporting their lowest pressure of 977 mb, with the eye just a few miles to its west. So I am sure the city experienced higher winds than that.
Fox 8 TV station in Mid City Nola reported a wind gust up to 114 mph.

What do the numbers mean on the map you posted?

He did a screenshot from the Entergy Outage Tracker Map. Those numbers represent number of customers without power.

Ida 2009's and Ida 2021's tracks look eerily similar, just like Dorian 2013 and Dorian 2019: (Although unlike Dorian, there was a random Ida 2015 inbetween)

[Category5Kaiju]

Ida and Gustav's tracks are quite similar too, but Ida clearly came closer to New Orleans at a stronger strength compared to Gustav.

Are you frigging kidding me??

They meant "work with" in a professional capacity . . . donating, fundraising, et cetera, obviously. Not "you there, with the boat, show me your non-profit papers."

Exactly. I worked for one of the groups I mentioned, in a high level position. While I was there, we performed background checks on all volunteers that would perform rescues. I personally worked to put this policy onto place, after we found a convicted murderer performing water rescues during Harvey.

As an ex police officer and cyber security expert, I also researched claims of fraud and abuse. I found one guy, after Harvey, who was calling people, saying he was with the "Cajun Navy." His reasoning was because he was a Cajun and he had a boat. He was doing this to figure out when people were at work, so he and his buddies could go steal everything out their houses. Of course, this dude didn't work with us, but these disasters bring the scammers out the woodworks.

About the pets, they ask this because they need to know what supplies to bring and which shelters to route you to. If you have animals, but don't have a pet carrier, we'll find one. We even found a boat to transport a man's pet donkey, because the sheriff refused to take it and he refused to leave without it. Many of them partner with animal rescue groups, to help facilitate extraction. Further, If you have pets, it's going to be hard to bring you to a shelter that doesn't accept them and it's even harder when you have to leave your cat behind. Idk if how many of us are still with that group, but we know why they ask, "do you have any pets?" Some of these groups take this very seriously.

...and about the coastguard, they are some fine people, but they don't have the resources to deal with something of this magnitude. During 2016, I was performing rescues in Sorento, La. The USCG has 1 boat, with a 12 HP engine, while there was a steady stream of citizen volunteers. They were doing more to help people launch their boats than actually rescuing people. During Harvey, they received so many phone calls, it either shut down their system or they transferred their phones to Washington DC, because they stopped taking calls at their local office.

I setup the software used by one of the groups, during Harvey, to receive, track and verify rescues and I can say there were over 3,500 people we pulled out of floodwaters and delivered to dry land, in 24 hours. I estimate the actual number being closer to 5500-6000, because there were boaters being sent into areas where there was no cell service for a family of 3 and they would come out with 10 people. We heard about this later in the day, so it never got officially recorded.

LARanger is correct. My comment was directed at donations, volunteer work and mentions. Rant over.

I for one really did not appreciate the slow speed of this storm. How many times have we seen a hurricane slam into NC or the east coast of Florida in the early morning and then by evening it's a depression three states away? Ida is just crawling...

[jhpigott]

Anyone seen drone footage yet of the damage? I'm sure there will be plenty later today once all the weather clears out. Not much out there yet, but I did see this video:

After nearly a day after landfall, Ida still looks better than Barry did at landfall.

That's honestly not a hard comparison to beat

I think Ida will be upgraded to Cat 5 post analysis. A sustained wind found by an observation of 149mph is clearly an indicator that Ida was extremely powerful. Also this was recorded after Ida made landfall so I think it will be upgraded.

After Eta and Iota I'm more reluctant about post-season upgrades. While recon didn't find cat 5 FL winds, the 140 kt dropsonde could be indicative of an upgrade (even though as people later said in the thread, it measures instantaneous winds instead of sustained winds). In that regard this measurement is more impressive as it is a sustained observation. What is the standard undersampling factor used for ships, 0.9? If so that would be 149/0.9 = 165 mph or 143 kt. Still, compared to for example Michael the evidence here is a lot weaker so I'd put upgrade chances at ~20%. Anyways, that's perhaps a discussion for another day, the most pressing matter now is the direct impact of Ida which unfortunately seems to be very big.

Eh, I don't think that's very compelling evidence. Just one of the rare cases where a ground observation reading confirms what the recon was finding.
