Automated system for description and I think it's outdated too cause didn't they delete their ECCCWeather accounts on that platform just near the end of last year for no apparent reason?

How Canada rates tornadoes officially changed in 2013 with this Ont. twister - The Weather Network On this day in weather history in 2013, the EF scale was used for the first time in Canada.

Canada decided to join its southern neighbours by adopting the EF scale on April 18, 2013, making the Sherburne, Ont., tornado the first one that was measured with the new measurement methodology. #ThisDayInWeatherHistory #ONstorm

I believe that tornado warning for Windsor might have been Environment Canada’s first-ever ‘Red Warning’. Which, while interesting, is something that IMHO breaks the logic of the new system ie. every tornado warning is a Red Warning, no matter the expected impact or confidence.

Hope she's doing better! ❤️

I feel like a "Tornado Warning (Yellow)" with impact level set to "high" and confidence level set to "medium" would be more warranted for that scenario and not a "Tornado Warning (Red)" that maxes out both impact & confidence levels. I'd expect that on a spotter or radar confirmed violent couplet...

Here's their description of "Impact" & "Confidence" levels btw:

Now say we have a QLCS spinup couplet coming through that is radar indicated, no CC drop (no debris detected on radar), and no spotter reports to confirm it's on the ground...

Their outlooks have the same impact vs confidence as they put in their colour coded warnings. If we went off of that alone then you can see how exceptionally rare a "extreme" impact matched with "very high" confidence is for outlooks alone but for tornado warnings? Crazy to be that high of impact-

Then this new system comes along and the first "tornado warning (red)" of the year gets issued with "Extreme" impact mentioned for a qlcs spinup's couplet? Idk anymore-

So genuinely lost.....

Doesn't help that almost every tornado warning we had last year always had the same "damaging tornado" description and "life-threatening situation" mentions that made every warning in the past feel like it was a PDS tornado warning when in reality it wasn't.

What confused me further was the "Extreme" impact tag.... It was a QLCS spinup (if it was even on the ground at that point). Though it's better to warn it rather than to not warn I don't understand how it wasn't like... "High" impact level and "High" confidence level vs whatever the heck that was-

Oh ya one of those

Severe thunderstorm threat isn't done with Ontario quite yet - The Weather Network Severe storm potential continues for southern Ontario on Wednesday, following 2026’s first tornado warning

That early Wednesday line of storms certainly packed a punch (mainly for OH/MI state line counties)! Here was Joshua Bridges' ominous view as the tempest trekked into Sylvania.

Day 5 (Saturday - April 18th, 2026) has a 15% overall severe risk (combine - we won't know the percentages for tornado, wind, and hail till Thursday - April 16th, 2026) partially over extreme SW Ontario (Windsor & Sarnia). 👀

Though the discussion specifically mentions more of a wind threat! #ONwx

Caveat here being that 5cm hail is listed as being where damage to buildings starts... but based on an EU study where much more of the building stock is tile roof.

Asphalt shingles, obviously much more common in US, take damage and need replacement at much smaller hail sizes.

Very large hail events and losses. Damage costs have risen in Australia, but this appears linked to increased exposure rather than an increase in the number of events.

Is damaging hail getting worse? An ESSL-led study published in Nature Geoscience finds that very large hail is modelled to occur most frequently in South America, the United States, and South Africa, but Europe shows the strongest increase in very large hail frequency. doi.org/10.1038/s415...
