Environment Canada is outlining the timing of a major winter storm heading to southern Ontario, including Durham.
They’ve issued a winter storm watch for the region and the storm is expected to begin Thursday night and last into Saturday.
They say precipitation will start as rain or snow late Thursday afternoon or early Thursday evening before transitioning to rain for many areas Thursday night.
Temperatures are expected to plummet on Friday morning, which could cause flash freezing.
Wind gusts of between 90 km/h and 100 km/h are also expected Friday morning along with blowing snow that could be heavy at times.
The weather is also calling for very cold wind chills Friday that will persist into the weekend.
We’re expecting between five and 15 centimetres of snow.
Environment Canada says you should avoid travelling if possible. Travel is expected to be hazardous in some locations due to the reduced visibility. Surfaces like highways, roads and sidewalks could become icy and slippery.
