Environment Canada has issued a severe thunderstorm watch for all of Peterborough County as well as eastern Northumberland County for Friday afternoon and evening (August 21).
Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts up to 90 km/h and large hail.
The thunderstorms are expected to develop Friday afternoon over the area and persist into the evening.
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. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!
