A thunderstorm watch has been issued in Chatham-Kent, as thunderstorms are expected to redevelop this afternoon across most of Southern Ontario.

Environment Canada officials say the main threats associated with these storms will be strong wind gusts and hail.

Some localized flooding is also possible.

“Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles,” forecasters say.

“Heavy downpours can cause flash floods and water pooling on roads. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors.”

Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce one or more of the following: large hail, damaging winds, torrential rainfall, forecasters say.

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

Please continue to monitor alerts and forecasts issued by Environment Canada.
