Severe thunderstorm watch in effect

Current details:
Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts, large hail and heavy rain.

Hazards:
Wind gusts up to 90 km/h.
Nickel to toonie size hail.
Torrential downpours.
Risk of tornadoes.

Timing:
This afternoon into this evening.

Discussion:
Thunderstorms will develop this afternoon. The main hazards will be torrential downpours and strong wind gusts. A secondary threat will be hail up to toonie size. Tornadoes cannot be ruled out, particularly west of the Golden Horseshoe and for areas south of Georgian Bay.

Large hail can damage property and cause injury. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Remember, severe thunderstorms can produce tornadoes. Heavy downpours are likely to cause flash floods and water pooling on roads.

Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!

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

Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce one or more of the following: large hail, damaging winds, torrential rainfall.
