1. checked satellite just now, eye is moving due west. marked it with the cursor to see nt

[Cheezoholic]

4. Please dont post misinformation

The NHC doesnt check movement with a cursor. Hurricanes wobble, especially strong ones. The overall motion is right along the NHC's track. This is a very dangerous situation, this storm is stronger than Katrina and will be stronger than Katrina at landfall. You checked it with your cursor. Get real man.

19. One of our local meteorologists in New Orleans explained last night

that the location of the center of the eye can be deceiving. He said that he has to use multiple sources to find the true eye. It can be difficult to place with just one type of imagery.

8. Thoughtful post!

6. Oh shit.

9. Looks like it wants to do an ERC

but might not get there before landfall. Looks like there is a ragged eye there.

12. I had to look up what ERC stands for

For those who don't know, it's the "Eyewall Replacement Cycle", which is basically the phenomenon wherein a powerful hurricane forms another eye around the previous one and eventually replaces it. The hurricane weakens during this process, but once the new eye replaces the old one, the storm re-strengthens.

18. Thanks for adding to the thread

This is a hobby of mine for over 50 years so...

What tends to happen with the stronger storms (if they have enough time to do it before hitting land somewhere on their path) is that as the pressure deepens and the convection around the central core starts wrapping around what is attempting to be or is a small eye, if the convection that is wrapping around closes off (and it normally does that in a wider radius than the eye), then the center starts to collapse (and weaken) as the circulation attempts to re-establish itself closer to the wider convective circulation... And if that is successful, the center of what was the old eye starts clearing, and a new eye (usually a little wider) is formed.

You tend to see this more with storms that are coming from a distance (i.e., to this hemisphere across the Atlantic) where they have enough time to intensify before encountering land. In that case, they can even go through a couple ERCs before a landfall.

10. This is a deadly storm - stay safe folks

[wnylib]

11. Wasn't 2021 supposed to be better than 2020?

[zuul]

20. So far it sucks.

[ashredux]

13. It's a Hoax...the Gov wants to control you, (Am I doing this right?). There is no Ida!

Radar? It’s not real !

[spinbaby]

14. That was earlier than predicted

Which is definitely not a good sign.

15. Wind speed now 145 mph

Just now on CNN

[malaise]

16. Now 145mph, this is the strongest hurricane that will hit Louisiana in over a century

Let that sink in!
The airport is more crowded than the one in Afghanistan and those are the people with means. This is going to be a catastrophe.

21. And on the New Orleans subreddit

A lot of them were refusing to evacuate. Whole neighborhoods were staying.

Life-threatening storm surge inundation is expected today along portions of the coasts of Louisiana, Mississippi, and Alabama, and could reach 9 feet or greater above ground level somewhere within the area from Burns Point, Louisiana, to Ocean Springs, Mississippi #Ida

Inundation could reach 12 to 16 feet above ground level from Port Fourchon, Louisiana, to the Mouth of the Mississippi River. This is a life-threatening situation! Everyone in the Storm Surge Warning area should follow the advice given by local officials http://hurricanes.gov

That potential of surge is akin to what happened in 2018 with Hurricane Michael's (as a Cat 5) landfall in Mexico Beach, FL - https://www.wtvy.com/2021/04/18/hurricane-micahel-storm-surge-catastrophic-for-mexico-beach/

23. Cat 4 storm means people on the margin can die. Right now, a lot of people are on the margin.

This is not looking good.

[NickB79]

24. CNN just said it hit 150 mph, only 7 mph short of a Cat 5

Gonna hit New Orleans dead on. Holy shit.
