Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts and large hail. Hazards: Hail up to ping pong ball size. Wind gusts of 90 to 100 km/h. Timing: This morning, and possibly into the afternoon. Discussion: Thunderstorms incoming from Lower Michigan will present mainly a large hail threat, with damaging winds becoming an increasing hazard through the morning. There is uncertainty with respect to further thunderstorm development this afternoon.
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. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors! The Office of the Fire Marshal and Emergency Management recommends that you take cover immediately if threatening weather approaches.
