Conditions are favourable for the development of dangerous thunderstorms that may be capable of producing damaging wind gusts and torrential rain.
Risk of localized damaging winds from thunderstorms.
Scattered thunderstorms are expected to develop over portions of the regions today. Some of these storms will have the potential to become severe with damaging winds and torrential downpours.
There will also be the risk for an isolated tornado.
The threat for storms will end over southwestern Ontario by mid afternoon, over the Golden Horseshoe late this afternoon, and over eastern areas early this evening.
Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. Heavy downpours can cause flash floods and water pooling on roads. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!
