Conditions are favourable for the development of severe thunderstorms which may produce tornadoes. Strong winds, large hail and heavy rain are also possible.
A line or area of thunderstorms is expected to push eastward through eastern Ontario this afternoon.
The main threats with these thunderstorms will be strong wind gusts and a tornado threat.
In addition, the moist airmass will allow for storms to produce torrential downpours. This is a dangerous and potentially life-threatening situation. Be prepared for severe weather.
Take cover immediately, if threatening weather approaches.
In the event of a tornado, or if a tornado warning is issued for your area, it is recommended you take the following actions: Go indoors to a room on the lowest floor, away from outside walls and windows, such as a basement, bathroom, stairwell or interior closet.
Leave mobile homes, vehicles, tents, trailers and other temporary or free-standing shelter, and move to a strong building if you can.
As a last resort, lie in a low spot and protect your head from flying debris. Lightning kills and injures Canadians every year.
Tornado watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce tornadoes.
The weather forecast today calls for 30 to 40 mm of showers with thunderstorms. A risk of a thunderstorm early this evening and light winds with a low of 14.
