Environment Canada has a snow squall watch for eastern Ontario communities along Lake Ontario Wednesday, asking people to consider postponing non-essential travel for safety reasons.
More than 15 centimetres of snow could fall around Kingston and Belleville starting early in the morning and that could happen in sudden blasts of two to five centimetres in an hour, forecasters say.
The very poor visibility means this advice to avoid travel if people can and to make a plan if they have to go out: have a charged phone, bring an emergency kit and tell people when you expect to reach your destination.
Much more intense snow squalls hit Muskoka over the weekend.
Kingston’s overnight low is expected to be about –3 C with wind chill making it feel more like –10. Wednesday should stay around the freezing mark and that night could see either snow or rain.
There was a snow squall watch for the area over the weekend and there are similar watches Tuesday morning on the north shores of Canada’s Great Lakes.
Environment Canada is also telling people in western Quebec to expect that area’s first significant snowfall of the season Wednesday and Thursday.
It forecasts 10 centimetres of snow, potentially a bit more in the hardest-hit areas and potentially affecting travel as well.
About five centimetres of snow could fall in Ottawa Wednesday, with a bit more at night.
Parts of the broader Ottawa-Gatineau area have been warmer and drier than normal in recent weeks, which contributed to the cancellation of an international ski event at Mont-Tremblant this coming weekend.
