Heavier snow in Renfrew County

A winter weather travel advisory is in effect for parts of the Ottawa Valley, including the Barry's Bay and Killaloe areas and the Petawawa, Pembroke, and Cobden areas.

The weather service is calling for between 10 and 15 centimetres of snow, falling heavily at times, which may lead to poor driving conditions. The heaviest snowfall is expected in the late morning and early afternoon.

"An Alberta Clipper will track across central Lake Huron on today bringing heavy snow and accumulations of 10-15 cm," Environment Canada says. "Accumulating snow will cause poor driving conditions, and impact travel."
