Before heading outside, check your local severe weather warnings today. Environment Canada has issued a severe thunderstorm watch for Toronto with potential wind gusts exceeding 90 km/h and hail up to 2 cm – conditions that can escalate quickly.
What is the severe weather outlook for Toronto?
Today’s severe weather outlook shows a strong cold front moving through southern Ontario this afternoon. Thunderstorms capable of producing damaging winds, large hail, and heavy rain are likely between 2 p.m. and 8 p.m. EDT. The severe weather radar indicates a line of storms developing near Lake Huron and tracking eastward.
How are severe weather warnings issued?
Environment Canada issues severe weather warnings when criteria are met: wind gusts ≥ 90 km/h, hail ≥ 2 cm in diameter, or heavy rain that may cause flash flooding. A warning means the event is imminent or occurring. Watches are issued earlier when conditions are favourable. For the latest, see our Canada Weather Warnings page and Weather Warning hub.
What is the difference between a severe weather watch and a warning?
A watch means conditions are favourable for severe weather; a warning means severe weather is occurring or imminent. Take immediate shelter when a warning is issued for your area.
Can severe weather occur in winter?
Yes – winter storms can produce blizzard conditions, freezing rain, and extreme cold. Severe weather examples include ice storms and heavy snowfall events that meet warning criteria.
