All of Midwestern Ontario is under either a winter storm warning or a freezing rain warning for Tuesday.
It's starting with blowing snow and a very strong easterly wind this morning.
Snow is expected to change to ice pellets and then to freezing rain Tuesday afternoon. Freezing rain may persist for several hours before changing to rain or snow in the evening. Wind gusts of 45 - 60 kilometres per hour can be expected through the morning and afternoon.
Total snowfall and ice pellet amounts of 10-20 centimetres are possible by Wednesday.
Across northern Bruce and Grey counties, snowfall amounts of 20-25 centimetres and blowing snow are likely into Wednesday. Visibility will suddenly be reduced to near zero at times in heavy snow and blowing snow.
Roads, sidewalks and parking lots will become icy and slippery. Ice build-up may cause tree branches to break, increasing the risk of hydro outages.
Drivers are reminded to make sure your vehicle lights are on if you have to travel and to maintain a safe following distance.
