At 8:00 CDT, Environment Canada meteorologists are tracking a cluster of severe thunderstorms north of Sioux Lookout capable of producing damaging winds gusts and dime to nickel sized hail. The most intense thunderstorm is located 50 km north of Sioux Lookout and based on radar it may be producing a tornado.

This is a dangerous and potentially life-threatening situation. Take cover immediately, if threatening weather approaches. If you hear a roaring sound or see a funnel cloud, swirling debris near the ground, flying debris, or any threatening weather approaching, take shelter immediately.

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.

In Canada, lightning kills up to 10 people every year.
Remember, when thunder roars, go indoors.

Emergency Management Ontario recommends that you take cover immediately, if threatening weather approaches.
