Environment Canada has upgraded its severe thunderstorm watch to a severe thunderstorm warning as meteorologists are tracking a line of severe thunderstorms capable of producing very strong wind gusts, pea- to dime-size hail and heavy rain.
This line of severe thunderstorms is located from Grassy Lake to 25 kilometres south of Beaverstone Bay, moving east at 65 km/h.
Hazard: 90 km/h wind gusts and dime size hail.
Locations impacted include:
Sudbury, Parry Sound, North Bay, West Nipissing, Huntsville, Valley East, Milnet, Nickel Centre, Wanapitei Provincial Park, Solace Provincial Park, Matachewan, French River, Britt, Markstay, Grundy Lake Provincial Park, Lady Evelyn-Smoothwater Provincial Park, Chiniguchi Waterway Provincial Park, Bayfield Inlet, Sturgeon River Provincial Park and Sturgeon Bay Provincial Park.
Take cover immediately, if threatening weather approaches, said Environment Canada. Heavy downpours can cause flash floods and water pooling on roads. 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.
Severe thunderstorm warnings are issued when imminent or occurring thunderstorms are likely to produce or are producing one or more of the following: large hail, damaging winds, torrential rainfall.
A severe thunderstorm watch is in effect for Greater Sudbury and vicinity.
Conditions are favourable for the development of dangerous thunderstorms that may be capable of producing damaging wind gusts and large hail. Potential hazards including wind gusts up 100 km/h, up to ping-pong-ball-sized hail and risk of a tornado.
Thunderstorms have developed over Michigan and are tracking towards the area, said Environment Canada. These thunderstorms are expected to strengthen as they approach. Thunderstorms are expected to move east of the area during the evening hours.
Large hail can damage property and cause injury. Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. Locally, heavy rain is also possible.
