Better stay indoors — Environment Canada has issued a severe thunderstorm watch for southern Ontario as a series of potential storms make their way across the region.
The storms are expected to form east of Lake Huron around noon, from Georgian Bay to Windsor. They will then track eastward across southern, central and northeastern Ontario by 4 pm, bringing heavy rains, hail, lightning and wind gusts travelling at speeds of up to 40 km/h.
Aside from Toronto and the GTA, the advisory applies to Halton, Peel, Hamilton, York, Niagara, Durham, Innisfil, Peterborough, Barrie and Simcoe. It will remain in effect tor the next nine hours, which means commuters may be caught in the storm tonight.
Environment Canada issues severe thunderstorm watches when atmospheric conditions are favourable for the development of thunderstorms that could produce large hail, damaging winds and torrential rainfall. The agency advises people to stay indoors as much as possible during the storm.
"Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles," the advisory reads.
Lightning is also of particular concern during these severe thunderstorm watches. According to the agency, southern Ontario is the most prone area to deadly lightning strikes in Canada. Just last month, multiple people (including 3 adults and 2 children) were injured by lightning strikes in Norfolk County.
