Get ready for some rain.
Environment Canada has issued a Severe Thunderstorm Watch for Perth County.
Thunderstorms are expected to begin this afternoon and last into the early evening. The agency says the conditions are favourable for a dangerous storm to develop.
Hail and strong winds capable of downing trees, damaging buildings, and blowing large vehicles off the road are a possibility. Heavy rain is to be expected as well.
Environment Canada is monitoring the situation and will issue more updates as needed.
