Lake effect snow squalls are expected to impact parts of Ontario throughout the weekend with peak snowfall rates of 2 to 4 in per hour, according to Environment Canada.

Heavy snow, poor travel conditions and power outages are expected in the Barrie area starting Friday evening and continuing at least through the weekend, Environment Canada says. Weather warnings have also been issued for other parts of central Ontario.

Difficult driving conditions continue into this weekend across portions of Ontario as powerful snow squalls continue whipping off all five of the Great Lakes. These potent bands of lake-effect snow will continue through Sunday,
