Severe thunderstorm warnings are also in effect for Ottawa South-Richmond-Metcalfe, Kaladar-Bannockburn-Bon Echo Park, Westport-Charleston Lake, Plevna-Sharbot Lake-Western Lanark County, and Tamworth-Sydenham-South Frontenac.
In Quebec, warnings are also out for the Lièvre River and Low-Wakefield areas.
