Tornado watch in effect in southern Ontario cities and towns

A tornado watch is in effect for a handful of cities and towns in southern Ontario today.

Conditions are favourable for the development of severe thunderstorms which may produce tornadoes in the Niagara Region today (July 10), Environment and Climate Change Canada said in the tornado watch notice.

Tornado watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce tornadoes.

Communities in the watch area include Niagara Falls, Welland and southern Niagara Region.

In addition to the risk of a tornado, strong wind gusts up to 90 km/h and heavy downpours are expected.

The timing is this afternoon and evening.

Thunderstorms are expected to develop this afternoon and will continue into the evening.

“There is the potential for these thunderstorms to become severe during this time frame, with the risk of a tornado as a primary threat,” Environment Canada said.

This is a dangerous and potentially life-threatening situation, the notice continued.

Environment Canada advises people to take cover immediately if threatening weather approaches.

People should go indoors to a room on the lowest floor and stay away from outside walls and windows in the event of a tornado. A basement, bathroom, stairwell or interior closet are recommended.

People should leave mobile homes, vehicles, tents, trailers and other temporary or free-standing shelters, and move to a strong building.

As a last resort, lie in a low spot and protect your head from flying debris.
