TORONTO -- Toronto drivers may be in for a slow commute Friday morning as Environment Canada issues a weather advisory calling for snow overnight.

According to the weather agency, Toronto can expect about five to 10 centimetres of snow by the middle of the day.

“The morning commute may be impacted due to low visibility in heavy snow at times and snow accumulating on untreated surfaces,” the advisory said. “Conditions are expected to improve Friday afternoon.”

City officials said that the snow is expected to start around 3 a.m. and that salt trucks will be on the roads around that time.

City spokesperson Eric Holmes said that snow plows will be on highways once there is two centimetres of snow on the ground and on major roads once there is five centimetres of snow on the ground.

Friday is expected to be partly cloudy with a high of 0 C and a low of -6 C with wind chill. There is a 40 per cent chance of flurries in the evenings, Environment Canada said, and the temperature is expected to continue to drop to about -13 C overnight.
