#ONStorm #ONwx Here’s a look at the aftermath of the historic snowstorm that slammed #Toronto today. The Danforth was one of many neighbourhoods that ended up completely buried, with snowfall totals topping 50cm in some spots. As cleanup gets underway, please remember to take your time and pace yourself while shoveling. Overexertion in heavy snow can be dangerous, and heart attacks during cleanup are more common than many realize. Take breaks, stay hydrated, and ask for help if you need it. - Brennen

#ONStorm #ONwx No, that isn't snow in late May - it’s hail covering Hwy 11 near Kearney (north of Huntsville) at 5 PM! Might need to bring those plows out of storage. 😂 Credit: Katie O’Hearn

#ONStorm #ONwx WOAH! 😮 It looks like we very likely had a tornado touch down in the Belmont area not too long ago, as the tornado warned storm moved through the area. Dr. Sills from the Northern Tornadoes Project agrees that this was probably more than just a gustnado, like what we were seeing yesterday, but it will still need to be confirmed. Huge thank you to Stephanie who shared this video via Ontario Storm Reports - Alannah May 19, 2026

"How did the Quebec wildfires start all at once?!" is a question we've been receiving quite a bit. We were curious too so we decided to review the data. Using GOES-16 satellite data for fire hotspots and by overlay lightning data, the answer becomes pretty clear. Of course, not all fires are caused by lightning. In rare cases, they can be caused by human negligence such as a bonfire that has gotten out of control, improperly disposed ashes, lit cigarette butts and even arson. Nevertheless, you can review the data yourself at: #Quebec #Wildfires #onstorm #Ontario #OntarioWeather

⚠️ Double check your ECLIPSE GLASSES! Jennifer, a Registered Optician and the Executive director of the Ontario Opticians Association has kindly put together this video explaining how to spot fake eclipse glasses She found a pair of counterfeit eclipse glasses to show you the difference between the real ones and the fakes. The second pair are the real ones. You should see nothing except the sun, reflections of the sun, the filament from incandescent blubs or a tiny bit of light from your phones flashlight If you aren't sure if your eclipse glasses are from a trusted brand, check to see if yours are on this list: Stay safe tomorrow! - Brennen & Adam

#ONStorm #ONwx Wow! 😮 I’ve never seen fog/smog this thick in my life. It’s like living in the clouds! ☁️ An area of thick fog has set up over Downtown #Toronto producing near-zero visibility. This fog is also mixed in with pollution that has nowhere to go, leading to reduced air quality as well. - Brennen

WOW! Simulated Tornadoes in the Virtuweather Game LOOK AMAZING! We built Virtuweather in Unreal Engine 5 (same game engine used for Fortnite and the television show; The Mandalorian) and we're able to use 3D radar data to simulate thunderstorms in real-time as well as spawn simulated tornadoes! #onstorm #wxtwitter Sign up to get notified when we launch the beta test at and get prepared to chase simulated tornadoes from the safety of your own home! - Adam
