Severe thunderstorm warnings were issued on Thursday by Environment Canada for a large section of Ontario which extends from London all the way into Quebec.
The first warnings were issued in the morning while the last came to an end by 5:30 p.m.
Environment Canada said that weather conditions had the capability of producing dangerous thunderstorms which could involve strong wind gusts, damaging hail and heavy rain.
“A line of thunderstorms is expected to continue tracking southeast today while strengthening (in force),” the watch read.
“The primary threat with these thunderstorms is large hail. This line is expected to move out of the area this afternoon.”
Some of the hazards connected to such thunderstorms included nickel-sized hail and wind gusts up to 90 km/h, while the area could also see heavy rainfall with totals reaching up to 40 mm.
Environment Canada warned affected residents to take cover immediately is they see storms approaching.
“If you hear thunder, then lightning is close enough to be dangerous,” it noted.
