The Environment Canada on Sunday issued severe thunderstorm watch for six regions in northern Ontario.
Atikokan (Upsala – Quetico), City of Thunder Bay, Fort Frances (Rainy Lake), Lake Nipigon (Wabakimi), Nipigon (Marathon – Superior North), Superior West, and Wawa (White River – Pukaskwa), are the six regions under severe thunderstorm watch.
Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts up to 80 km/h, hail size of 2 cm and heavy rain, the Environment Canada said in a statement.
Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles, the statement said, adding that severe thunderstorms can produce tornadoes. Heavy downpours can cause flash floods and water pooling on roads.
The Environment Canada also added that lightning kills and injures Canadians every year, urging the residents of the area under watch to go indoors when thunder roars.
Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce large hail, damaging winds, torrential rainfall.
