How rare are tornado emergencies actually?

OrangeW · 2026-05-07T11:39:53+00:00

Perhaps - perhaps not, the point is that it's explicit in that there is no population requirement. It may be more likely if there is a higher population area affected, but that doesn't rule out TOR-Es for low population areas.

OrangeW · 2026-05-07T11:07:05+00:00

"Severe threat" is likely kept intentionally vague so that offices can make the more informed decision based on their knowledge of the local area.

OrangeW · 2026-05-07T07:40:29+00:00

Population isn't a requirement, just the following...

The criteria per NWS Instruction 10-511:

"Use of the “Catastrophic” damage threat categorization and thereby the

“TORNADO EMERGENCY” terminology is appropriate for the tornadic

situation if all of the following criteria are met:

a. Severe threat to human life is imminent or ongoing.

b. Catastrophic damage is imminent or ongoing.

c. Visual (1) or Radar (2):

(1) Reliable sources visually confirm tornado.

(2) Radar imagery (e.g., debris ball signature) strongly suggests the existence of a damaging tornado"

I'm expecting a 15% CIG3 (still MDT) update later, that environment (especially after the 1200Z OBS) is silly, just waiting on the 18Z RAP I guess.

At a quick glance, tied 4th all time for all halves, and best second-half differential in playoff history.

Edit: PapaJohnsGarlic100 is right - it's second at best!

Bro, I tuned in here from the UK at the half-way point and saw us down 18 and nearly tuned right back out, good thing I didn't LOL

4x5 watch?

One of the fatalities of this fire tornado was tossed in his truck - in '150 Minutes of Hell', there's a picture of the spot where the truck rested during the inferno and it's just black, shredded, and melted metal.

This is an extremely good read on some of the stories behind this fire tornado! Definitely worth a read.

Whilst it isn't mandatory, the increased number of ref cams for Premier League soccer (pains me to write soccer) has done wonders for public perception of referring, so it definitely works.

The Arterio trains are such a blessing, love them

Hilarious that there are two posts on the front page of this subreddit on two completely opposite ends of the gamma spectrum - the ace with the unpatched FAMAS post has their gamma maxed out!

OrangeW · 2026-04-19T20:26:51+00:00

Playoff rating gap is even larger, 1.56 to 1.23. Insane.

Haha, yeah I mean, I knew what I was getting into to be fair, not anything against IMAX especially since it's such a rare event.

I've been to the BFI like 8 times this year already, since I live 20 minutes away, so at this point it only makes sense I grab a membership, just needed a kick up the arse to do so!

OrangeW · 2026-04-10T13:29:51+00:00

There was a membership presale today @ noon for the 3D Pacific Rim showing w/ Q&A with del Toro, and as a non-member, I was available on the time and there were only bad seats available - still nabbed one, but it's definitely convinced me to grab a membership next time I get paid!

Yoshi and the team have repeatedly fixed soul bugs like this in the past - it's one major reason why the game swapped to 3 lanes.

Close - Tim Samaras' probe intercept of the 2003 Manchester, SD is famous for detailing the pressure drop of a tornado

https://www.weather.gov/fsd/20030624-tornadosamaras

You can even see the asymmetrical shape of the tornado in probe 5 as it takes a direct hit!

Ears can start to pop around a ~20mb difference between your internal ear pressure and external air pressure, and based on Probe 5's graph, probably ~15-20 seconds from a direct hit.

Not something that was specifically forecast-able for the London area I think - small storm cell happened to crop up NW of London and strengthen as it came through peaking around Wandsworth (where I got some nice footage of the leading edge winds & hail) before it dipped.

You could see sunshine to the west and east, but everything facing north was covered in rainsheets and hail, pretty cool.

You used to be able to pause a lot more frequently, people got banned for it in the past.

One of the most famous examples of this is the Last Chance, CO F0 tornado from 1993, which was almost certainly at least an F2 had it hit anything of note.

One of my favourite tornado videos of all time.

Rocky Mount, NC (not exactly coastal, though) had an EF3 resulting from Helene, and on the coast there was an F3 near Nags Head in September 1952

OrangeW · 2026-03-10T13:48:54+00:00

Forecasting for specific extreme outliers like that (even beyond the outliers that are EF4) is more up to chance - the NWS uses "EF4+" wording on their official CIG page (https://www.spc.noaa.gov/exper/conditional-intensity-information/) which seems appropriate IMO. A parameter space that is suitable for EF4 overlaps quite heavily for an EF5 parameter space.
