Environment Canada ended severe thunderstorm watches and warnings for a large swathe of southern Ontario on Tuesday evening.
The agency issued the warning and watches to an area that stretched from Windsor to Quebec and along the shores of Lake Huron and Georgian Bay during the afternoon.
The affected areas included the northern portion of the Greater Toronto Area, Ottawa, London, Guelph, Kitchener-Waterloo and Barrie as well as a good portion of cottage country including the Muskoka and Kawartha Lakes areas.
Toronto and Hamilton were later added to the watches. Warnings, a more severe measure, were also issued in some places, including Peterborough and Uxbridge.
By 9 p.m. on Tuesday, all warnings and many severe thunderstorm watches had ended.
Sarnia, London, Woodstock and Hamilton were all cleared by Environment Canada as the evening went on. Stratford, Waterloo and Kitchener also saw the threat of storms move on.
Environment Canada says that severe thunderstorms can potentially come with tornadoes.
People should avoid being on the water in case of violent and sudden gusts of winds and also take cover if a storm is approaching.
“Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!” the warning says.
By 10 p.m., only Windsor, Chatham-Kent and areas near Ottawa were still covered by severe thunderstorm watches.
