Environment Canada has issued a severe thunderstorm warning for Chatham and the surrounding area, which tapers off into a severe thunderstorm watch as you move north toward London. Meteorologists are tracking a severe weather system capable of producing very strong wind gusts up to 100 km/h, nickle to toonie sized hail, and heavy rain which could exceed 50mm. This storm is expected to hit the area this afternoon. If threatening weather approaches, take cover immediately.
