(Rick Madonik / Toronto Star)School buses have been cancelled for York Region District School Board, Durham District School Board, Durham Catholic District School Board, Halton District School Board, Halton Catholic District School Board, Dufferin Peel Catholic School Board and Peel District School Board, but schools themselves remain open.Toronto District School Board tweeted that their school buses would be running, regardless of weather, but warned that weather-related delays were possible. Although the snowfall will begin in the morning, Environment Canada said in their alert that the heaviest snowfall is expected to hit in the afternoon, meaning the afternoon commute could be a messy one, particularly as the wind is expected to pick up from 20 km/h to 40 km/h, leading to blowing snow. According to the weather agency, higher amounts of snow could also accumulate in areas closer to the lake shore, particularly near western Lake Ontario, resulting in up to 20 cm of the white stuff in some locales. Pearson Airport tweeted early Wednesday to warn anyone travelling by flight today that the snow could cause delays. They are asking customers to check the status of their flights online before heading to the airport. The added snow comes with chillier temperatures: there’s a predicted low of -17 C with the wind chill for today, and a high of only -6 C. Once the snow ends Wednesday evening, thingsare expected to warm up slightly. Thursday has an expected high of -3 C and a low of -15 C.Alexandra Jones is a breaking news reporter, working out of the Star’s radio room in Toronto.
