Environment Canada has issued a severe thunderstorm watch for Newmarket and northern York Region, with strong wind gusts, large hail, torrential rain and also tornadoes possible this afternoon and evening.

Potential hazards include wind gusts near 90 km/h, nickel size hail and torrential downpours with rainfall in excess of 50 mm, according to the warning.

"Some of these thunderstorms may become severe with strong winds, large hail and heavy rain. Tornadoes also can not be ruled out. The potential for severe thunderstorms will come to an end this evening," the agency stated.

Large hail can damage property and cause injury, while 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 can cause flash floods and water pooling on roads. Stay indoors when a thunderstorm strikes. There isn't a place outside that is safe during a thunderstorm."

The Office of the Fire Marshal and Emergency Management recommends that you take cover immediately if threatening weather approaches.
