Environment Canada warns Peterborough County and Kawartha Lakes areas that severe thunderstorms are in store for the afternoon of Sept. 19.
Conditions are favourable for the development of severe thunderstorms capable of producing strong wind gusts up to 90 km/h, large hail two to three centimetres in diameter and heavy rainfall.
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. Heavy downpours can cause flash floods and water pooling on roads.
