Environment Canada has ended all severe thunderstorm warnings and watches for Sarnia-Lambton.
The weather agency says conditions were previously favourable for the development of severe thunderstorms capable of producing heavy rain.
Isolated thunderstorms were predicted to develop early this afternoon and continue into this evening.
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.
