Though The Weather Network had warned the public of overnight thunderstorms that could potentially bring heavy rains, intense lightning, hail, and yes, even tornadoes to Southern Ontariolast night, citizens were still shocked to see how severe things became, and how quickly they escalated.

A tornado watch for the east of the province and portions of Quebec was upgraded to a warning as conditions worsened today, thanks to a highly turbulent and convective storm system.

If you’re in the south of Ottawa please take the tornado warning seriously & stay safe! ❤️https://t.co/EGEy1hW9qo

Roads in and around Toronto were messy and slippery amid torrential downpours early Thursday morning, but things appear to have brightened up in the city as the day has worn on — which is certainly not the case further eastward.

Alarming footage of a tornado touching down in Barrhaven, Ontario — a 25 minute drive south of Ottawa and just over four hours from Toronto — has been popping up on social media, showing terrifyingly powerful winds whipping up shingles and various materials.

Wow - be safe!

A rotating cloud was seen ripping around residential streets in the area under darkened skies as police, firefighters and other emergency personnel responded to the scene.

Locals say that authorities have been knocking on doors on some of the hardest-hit streets to check in and provide assistance, and also to shut down gas and hydro to prevent further issues.

OMG WHAT

Severe thunderstorms bringing high levels of precipitation and strong windsare expected to keep ragingacross the Ottawa Valley.

Those in areas with active tornado warnings can anticipate winds up to 100 km/h, and should stay away from mobile shelters, windows and doors, and worst case, cover themselves with a mattress or sleeping bag in their basement, if possible.

Everyone should also keep up to dateon the latest newsfrom credible weather agencies, as warnings have been repeatedly issued, ended, and re-issued in the last few hours.

Wow
