Environment Canada says heavy rain could cause flash flooding and significantly reduce visibility. Strong wind gusts may also bring down tree branches and lead to localized power outages. The weather agency is urging motorists not to drive through flooded roadways.
Emergency Management Ontario advises people to take cover immediately if threatening weather approaches.
Residents are encouraged to monitor forecasts and weather alerts from Environment Canada as conditions continue to evolve.
Earlier Tuesday, Environment Canada warned the storms could also produce large hail, but that hazard is no longer included in the latest warning.
Severe thunderstorm watches remain in effect for other parts of southwestern Ontario, including Kitchener-Waterloo, Windsor, Chatham-Kent and Sarnia.
