August 29th is a hell of a date for Louisiana

Hurricane Ida tied Hurricane Laura (2020) and the Last Island Hurricane (1856) as the strongest hurricane on record to make landfall in Louisiana, with maximum sustained winds of 150 mph at its point of impact near Port Fourchon. The storm made landfall on August 29, 2021, and caused catastrophic damage, particularly in southeastern Louisiana, leaving over a million people without power.

Here it is on radar, showing the western eyewall over Ascension Parish and the eastern eyewall over Livingston Parish







She was a big one, and much stronger than Katrina. Had she made landfall 40 miles to the east, we might have had a repeat of Katrina, possibly even worse.

I got the hell out when I saw what Ida was turning into. I offered to pick my parents, brother and SIL up on the way out and they insisted they were staying. The strongest parts passed right over their houses. My mom said they spent all night awake in the hallway praying for it to end. She said she'll never ride out another one like that.

That third loop is deceiving for Houma. On IR it looks like they got in the eye, but they never did. It was just hours of getting raked and battered by the eye wall as it slowed down to a near stall and began to make its turn.

Ida was a monster. Rode it out in old Mandeville. Didn't even get the eye wall, but Ive never seen wind make 80 foot tall, 4 foot diameter pine trees bend as far as Ida did. And that bitch just came to a crawl once it hit land.

The 'Houma' label on that third loop is SE of Houma. The small '+' NW of the label is downtown Houma - which was close to but never in the total clear of the eye as you pointed out.

The Ida track was about as bad as possible since the eastern eye wall devastated the towns along Bayou Lafourche (where I live) and the western eye wall devastated the towns along Bayou Terrebonne south and north of Houma and Houma itself without either bayou having much - if any- of the total calm of the center of the eye..

Many structures that had never been significantly damaged by Hurricane Betsy in 1965 or any other hurricane before or after that until Ida were damaged by wind and/or wind-driven water.

In case anyone has not seen this video of Ida from Chauvin, LA (south of Houma), it is an impressive display of the power of nature. It is from a homeowner and is definitely not a professional video nor is all the commentary safe for work (NSFW).

I linked it to start at the most intense part, but you can also watch the entire video. 6:30 to 18:00 is the must-see part.

Got 4 to 5 inches of water in my house in Hammond, stout came and helped me put it back together.

I never thought we would flood since we didn't in spring or fall off 2016, but ida dumped almost 30" of rain on Hammond.

Just no. Katrina may have begun degrading with its maximum winds dropping when the ERC failed and dry air began to intrude but Katrina was still massive and stronger compared to Ida.

A better measure is the integrated kinetic energy. At landfall, Katrina was a whopping 113 terajoules and Ida was 36 terajoules.

Ida's eye wall was full of mesovortices. I remember waiting for the first satellite images of storm damage to be posted becauseoin radar it looked like those mesovorts were a big problem, and they were. A lot of the damage in that area (Houma and the areas that dealt with the right from quadrant extensively) looked like tornado damage.

Can confirm that. Watched a 70 foot section of fence get lifted out of the ground vertical and slammed back down in Ida’s eye wall.

Depends what you are talking about. Wind wise, yes. Ida was stronger. So was Laura, for that matter. But Katrina had a mind boggling storm surge of 25’-28’, twice that of Ida and Laura.

You guys did a great job of getting some posters to evacuate … o e guy was hesitating to leave his grandparents … but the hurricane hunters were grounded and TWC was behind in info iirc.

All I know is I trust info here first and this is my weather info source.

Yeah. We all had damage, but driving around you could see that some small areas had more significant structural damage whereas homes of similar age and similarly-built may have only had shingle and siding damage.

The home of an aquaintance of mine was one of the few newer brick homes that was structurally damaged beyond repair with the second floor being partially ripped off the bottom floor by what had to have been a small mesovort of some sort. Neighbors' houses only a few feet away had damage but nothing like that.

2020 and 2021 weather was a real arse to Louisiana. Just an insane amount of extreme weather.

I was going to comment that in hindsight it’s wild that we got Laura and Ida in back to back years. Both were right on the edge of 4 and 5 and I’ve seen some people say both should have been rated 5.
