A rain watch warns that extreme thunderstorms could develop in the region Wednesday morning through evening.

Climate Canada says there could be wind gusts of up to 90 km/h with "ping pong ball" - hail estimates.

"Storms are forming over Michigan and should track east into Ontario today or tonight," the watch said.

"With the Incomparable Lakes freezing, there's a lot of vulnerability right now in terms of strong areas in terms of what the storms will be like as they move into Ontario."

They say that assuming the storms overcome the cold temperatures on the lakes, they will reach the area before dinnertime anyway.

"Huge hail can damage property and cause injuries. Strong gusts can throw objects, damage fragile structures, snap tree limbs and overturn large vehicles," the advisory said.

"Remember, severe thunderstorms can wreak havoc. Lightning consistently kills and damages Canadians. Remember, when thunder rolls, go inside!"
