Friday's winter storm that is expected to leave at least 15 centimetres of snow has cancelled school buses across eastern Ontario and led to warnings about road safety.
Winter storm warnings remain in effect for many communities along the Ottawa River, including Ottawa-Gatineau, Prescott-Russell, Lanark County and the Arnprior and Barry's Bay areas. Cornwall is also included.
In all, 15 to 25 centimetres of snow is expected in Ottawa before it tapers off as afternoon turns into evening. Cornwall may get slightly less.
The Bancroft and Pembroke areas have snowfall warnings.
Pembroke could get close to 15 centimetres of occasionally heavy snow, Bancroft could get 15 to 20. The snow is also expected to dwindle by evening.
There are special weather statements about snow Friday along Lake Ontario.
About 10 more centimetres of it are expected, possibly with a little less closer to Belleville and a little more near Brockville.

The weather station at Ottawa's main airport has reported light snow or light freezing drizzle since early Thursday morning, with 11 centimetres falling Thursday. It had three centimetres all month before that.
