Environment Canada damage survey teams will be checking to see if three possible tornadoes touched down in Ontario Wednesday.

Severe thunderstorms ripped across central Ontario late Wednesday afternoon and left more than a dozen communities under tornado watch Wednesday evening.

The thunderstorms passed through Arthur, Ont., to Orillia, Ont., to Minden, Ont. The communities are about 155 kilometres apart.

The thunderstorms moved eastward, according to Environment Canada's special weather statements for the province, and maintained their severity as the passed over parts of eastern Ontario.
