Enhanced Fujita Ratings Debate Thread

I agree with you all that the EF scale needs work. What I don’t agree with is acting the way you do by directing a bunch of nonsense, borderline abuse, at the NWS’ offices on Twitter. Yes, it’s childish. The person running those social media accounts most likely didn’t have any say in the survey and are constantly taking a beating by weenies on Twitter. There isn’t some grand conspiracy to stick it to you all by screwing up ratings by the NWS.

I am not actually that angry I am really more stunned on how stupid some of these NWS offices act.

Do you think the Shawnee tornado of 5/19/13 was an EF5? I didn't think so at first, but after seeing Oakhurst classify it as one I started to question myself just a tad. I've also dug up some interesting things on Nitter:

This post, in which Nick K. shares a rumor he heard

The most "immediate" Before in a Before/After pic I've ever seen

The post that started it all

And, of course, Ben Holcomb hilariously busting after correctly identifying the location of the main show the day before, because despite it being off topic I still find it funny

What do you say, folks?

I know the motion of a tornado usually can mean the potential damage a tornado can ensue. That thing has some of the most wildest, video game, looking motion I’ve ever seen from a tornado. Had it hit Shawnee you MIGHTVE gotten the EF5 rating.

Sad to see that the Plevna tornado which had the most impressive velos i have ever seen live, will likely be rated an ef4, if not lower. Unless some miracle house was in its path. (By some cruel twist of irony there was a seemingly well built house by haviland that was directly hit... but it was torn down last year).

- you can check on google earth

1. Probably shouldn't describe a house getting hit by a tornado as a "miracle" in any way
2. The contextuals I have seen are actually really lackluster in comparison to what you'd expect from a signature like tnat, and an EF4 rating would be appropriate for that tornado.

1. Yeah bad wording
2. Have you seen contextuals from outside Plevna? I haven’t been able to find any, but I do think the tornado was occluding and lifting when it passed by Plevna.

After a very quick count on the wiki page for “EF4” tornados in the US, I counted at least 8 tornados that slabbed “well-anchored” or “anchor-bolted” houses. If you can’t even get an EF5 off well-anchored houses, what can you get them from?

A low-end EF4 rating would be appropriate given the circumstances of this tornado. It was 100% capable of producing EF5 damage. Also today is the 12 year anniversary of the last tornado to be rated EF5 ,which of course was in Moore, OK.

Yup......though it's not the last tornado to reach that intensity.

If I had my way with the ratings, we'd be rapidly coming up on the 1 year anniversary of the last EF5 in Sterling City, TX.

I call this the “Hollister dilemma”, where there’s just a weird radar-to-intensity disconnect. Of course it’s named for the Hollister EF1 last year that was called one of the most powerful ever, but I could say that’s what happened here. Upper-level rotation in the storm were stronger than the tornado itself, creating the “but it was an EF5” problem. The Essex EF1 this year had the exact same thing happen.

It's entirely possible it reached EF5 intensity. It was super impressive both visually and on radar, and it produced high-end contextual damage:

I believe this is the Roll-Montpelier EF3 of May 27, 2019 The Van Buren EF2 that preceded Roll-Montpelier Akron, IN EF3

Here's an aerial photo taken the following month near the mobile home park NW of Bethel Acres:

Anyway, that said, I don't think 190mph is egregious. It doesn't stand out as a clear-cut EF5 like, well.. [insert long list of tornadoes we've been carping about forever] lol

Wow, I could see the scar just by briefly glancing at the image. Yea, definitely violent contextuals, but didn’t it hit mainly mobile homes? Most intense+ tornadoes can obliterate mobile homes.

Mostly, yeah. It destroyed a few site-built homes as well, but IIRC all the ones I've seen had some issues (CMU foundations, weak anchoring, etc).
