SARNIA, Ont. -- Environment Canada meteorologists are heading to the shores of Lake Huron on Monday to investigate storm damage and the possibility of a tornado in the area.
Environment Canada had issued watches and warnings about severe storms Sunday, and upgraded those at one point to tornado warning for eastern Lambton County.
"They were seeing signs of rotation within the storm cell as it came on shore from Lake Huron," warning preparedness meteorologist Geoff Coulson said.

"From the initial eye-witness reports we're been hearing, the worst of the wind seem to happen with the rain itself, so that could mean a down burst event."
That involves a damaging burst of winds, along with rain, he said.
"Or, it could in fact, still indicate a tornado, but it was literally wrapped in rain, so it was difficult for any of the eye witnesses to see it," Coulson said.
"That's why the meteorologists want to go and take a look."
Long and narrow damage paths can indicate it was caused by a tornado, Coulson said.
