A tornado warning issued Sunday afternoon for most of southern Ontario has been cancelled, but watches for severe thunderstorms continue for many parts of the province.

According to Environment Canada, weather radar at 2:15 p.m. ET picked up a line of severe thunderstorms capable of producing tornadoes. The storms southwest of Detroit were moving northeast at 60 kilometres an hour and were expected to reach the Windsor area around 2:45 p.m.

"These storms will also be capable of producing wind gusts to 100 km/h, torrential downpours and large hail," Environment Canada said in the news release.

The warnings were issued for Windsor, Leamington and Essex County — and later expanded to include Elgin, London-Middlesex, Simcoe, Delhi, Woodstock, Tillsonburg, Oxford County, Goderich, southern Huron County, Stratford, Mitchell, southern Perth County, Chatham-Kent, Sarnia and Lambton.

"A hot and humid air mass settling over southwestern Ontario has made conditions favourable for the development of severe thunderstorms … Isolated tornadoes will be possible with these storms," said Environment Canada.

But by 4:30 p.m. the storms had passed and the tornado warnings were rescinded.

Severe thunderstorm watches continue for many other areas of the province, including Brantford, Hamilton, the Niagara Region and Waterloo.

On June 6, a suspected tornado touched down in Leamington, Ont., causing severe damage to homes and businesses.
