A snow squall watch has been issued for the above regions. The radar map shows that snow is hitting the area, with reports of moderate snow and poor visibility.
Environment Canada warns:
“Snow squalls are expected to develop. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate.
Conditions will become favourable after midnight tonight for the development of snow squalls from Lake Superior in a cold southwesterly flow that is expected to develop in the wake of a cold front.
The snow squalls will continue for much of Wednesday before being pushed to the south of the region by Wednesday evening by another cold front.
Snowfall amounts of 10 to 15 centimetres per 12 hours are possible in the strongest snow squalls.
Driving conditions are expected to deteriorate quickly after the lake effect snow develops.
Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow. Consider postponing non-essential travel until conditions improve.
Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.“
