Hurricane Ida - Another Katrina in the Making?

As a fledgling forecaster back in 2005, I traveled to and experienced the aftermath of hurricane Katrina, first hand. I moved to the Mississippi Gulf Coast, not long afterwards. Near Waveland, Mississippi I observed 20+ storm surge for the first time in my life, and saw neighborhoods wiped clean, except for the slabs and the washing machines. It was surreal ...

According to Levi Cowan:nw: the best young PHD forecaster I know for tropical systems, the key concern for Ida is the favorable upper level environment, coupled with the Gulf Stream Loop Current, which sits directly in the path of Mt. Ida.  This is a big problem for the Gulf Coast, because this is going to provide a substantial boost to the storm, just before she moves inland. I don't think Ida will have the highly advantageous upper level venting profile that Katrina did, but at the surface, we have perfection ...

At the 12 minute Mark is Levi's discussion.

The etymology of Ida has an interesting ancient religious context, related to “Mountain Mother.”

It reminds me of an oldie but goodie ….

AND:  Mt. Ida is a town in Arkansas and a shortleaf pine tree ring chronology.

The name Ida in this case came from a railroad magnate's daughter.  Idabel in Oklahoma is the combined names of his two daughters, Ida and Belle.  His wife's nickname was Queen; hence, DeQueen, Arkansas.  Keeoing it all in the family.

I was referring to the ancient religious context, which is why I linked that reference.  The general consensus seems to refer to "Mountain Mother." Generally, you also see "mountain" with "ida" in the etymological references.

When I researched this hurricane name in prior years, I came up with "Mountain Mother," also.

Ida appears to be taking a breather, after passing over Cuba's Isle of Youth, which we've seen in prior years, also.

My concern right now is for New Orleans, which cannot handle a Cat 5 to their levee system. It will go under, again, and people will drown, again.

They need to be moving these people out of harms way, now, and that includes poor people who cannot move themselves. If the same mistake is made again, what will that tell U.S. about ourselves, as a first world nation?

Camille looked similar from 69

I was 8-years-old and 250 miles away when Camille came ashore and I lived in Jackson Mississippi in 2005 (45)  when Katrina rolled over New Orleans and paid us a visit up there and STILL, I can tell you, Camille was a FAR worse storm. It was a very small, compact storm but it is still the standard by which all the rest are judged along the Gulf Coast.  Not to put too fine a point on it but Katrina only killed as many as it did because corrupt politicians in the Parishes around N.O. used the billions that they received from Uncle Sugar to divert to uh... "other contingencies" :angry:  To this day, despite huge amounts of evidence of what they did, not one indictment for it.  I hope, for the sake of those in the path this time, they spent the money on the levies and pumps :( 

I feel badly for them, I certainly don't want a visit from a Cat 4 but the fact that they think it will suddenly go from a Cat 4 to a Cat 1 as it reaches the coast is very unusual.  The water in the shallows at the coast must be much cooler than normal.

Hurricane Ida is currently undergoing rapid intensification. She is now projected to reach Category 4 status as she arrives near New Orleans in two days, as the most recent projections from the National Hurricane Center, show:

The big question, now is, can the New Orleans levee system handle a Category 5 super surge, coming at the perfect angle to push water into the city, and at high tide? The answer is an emphatic, "no."  They did not build the levee system to withstand a Category 5 storm surge, after Katrina, and this means that this could potentially be another multibillion dollar catastrophe to add to the Federal balance sheet, when it can least afford it. Unless, you want to add another half a trillion to the infrastructure bill.

greater New Orleans. Experts say that is not enough.

Oh, I wouldn't worry overly about that.  Our media will ignore most of it unless there's some BOM angle they can attach to it.  Remember the "fiery but mostly peaceful" riots?  

I'm more concerned with whether the current administration in N.O. will take care of their responsibilities this time rather than forgetting their people as a means to harm the guy in the WH.  Oh, wait, it's a Biden, not a Bush.  Nawlins folks should be fine...

If I didn't have transportation I would grab what I needed and start walking now. To heck with waiting on someone to help get me out of harms way. I'm sure the buses are running. They'll get you a good start.

The only one I had to endure up close and personal, so to speak, was Frederick in 1979.  It was a "strong" Cat 3 and that was the only time in my life before or since when I actually thought I wouldn't live to see another sunrise.  The sound of that kind of wind is like you're hearing a living thing outside the doors and windows.  I can't even imagine a Cat 5.  I'm praying that the folks over there leave while they can.

Hurricane Ida is expected to hit as a CAT 4. The Gulf is exceptionally warm now. I don't see anything about any cooler coastal water that will weaken the storm. I hope everyone in danger is getting out. Now.

https://www.accuweather.com/en/hurricane/hurricane-watches-issued-for-new-orleans-parts-of-gulf-coast/1006485

Our local news is saying it will hit sometime Sunday night with 10-15 ft storm surge, 10-20 inches of rain and winds around 140 mph. Earlier tonight they mentioned the hospitals preparing as they have quite a number of Covid cases. Terrible scenario. I'm waiting for the 11 pm news now to hear. It should be on in an hour. It's expected it could bring more rain to us Wednesday into Thursday.

Perfect Angle + Slow Motion Turn at Landfall + Rapid Intensification + Possible Category 5 + Possible 20’ Storm Surge = Deadly Serious For All Land, Air Breathing Animals 

If you do not have wings to fly out - You should be Driving or Riding Out of New Orleans ….

New Orleans Mayor says “No Time for Evacuation” 

Meanwhile - This is could be way worse than Katrina, because intensification will be occurring at landfall.

When one of these monsters is intensifying at landfall, which is rare, it’s effect is more like a giant tornado. Don’t think Katrina, think Camille, mayor.

So I think some of our amateur prognosticators here. were correct. @and then 

The good news is, so far the wind field is not of sufficient size to produce a 20’ storm surge, but that’s is a problem, she looks small, when she’s planning to give you a giant middle finger.

Traffic jams as those with vehicles flee Ida, a..k.a. Earth Operation “Mountain Mother.”

While this is a good sign, what I want to see is the lower ninth Ward of New Orleans, to see what the poor folks are doing. Do they even know the “Mountain Mother” is coming?

If anyone has seen any media about the lower 9th evacuation, please give U.S. a view.

Compare Katrina to Ida on the same date 8-28-2005/2021, at roughly the same position in the Gulf.

Which would you rather be facing? The monster that had already peaked and that moved to the East of New Orleans, or the monster that likely won’t peak until landfall, tomorrow… and is coming in just to your West?

I think I would pick Katrina over Ida … unless I was Forest Gump ….

Its actually quite normal for hurricanes to quickly diminish when coming into contact with land. The wind has to deal with something sticking up and solid and it creates a braking effect.

Shallow coastal water will be as hot as water further out in the Gulf.

I drove over to see my sister who lives in the Mobile, metro area and I10 was nearly gridlocked headed back east.

Perhaps it's the scale of the map I'm looking at but most storms I've lived through, either at a distance or "up close and personal" ;)  have gone down rather more slowly than they seem to predict for this one.  As an example, we moved up to the Jackson, MS area a couple of decades back and were far enough "in-land" to feel like we wouldn't be bothered by hurricane winds any more.  Katrina came through that area as a Cat 1.  That's about 160 miles from the putting your toe in the Gulf.  Anyway, I sincerely hope that those who CAN get out, WILL get out.  The problem so many usually come up against is that work or other commitments force them to stay until everyone is trying to get out at the same time.  My sister once stayed on the road for 8 hours trying to leave Mobile and drive to Jackson.  It's miserable to be in gridlocked traffic in that circumstance.

The National Hurricane Director in his latest advisory says, wind damage in New Orleans will likely be “catastrophic.”

20” of rain + a 15’ storm surge will test the upgraded levees, that’s for sure. It’s not much room for error, is the problem. As I understand it, some of the levees are only 18’ foot above sea level.

It’s easy to find many articles on the Internet, where the U.S. Army Corps of Engineers admits that the levee improvements made following hurricane Katrina, are not designed for a CAT 5 storm, and we are knocking on that door, by a slim margin.

I was also in Frederick...in Gulfport on the CB base...where were  you?
