Snow squalls are expected. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate.
WARNING FOR Sault Ste. Marie – St. Joseph Island
Agawa – Lake Superior Park
Searchmont – Montreal River Harbour – Batchawana Bay
Snow squalls have developed in a cold northwest flow off Lake Superior and will begin to affect Sault Ste Marie early this morning. Snowfall amounts of 10 to 20 cm per 12 hours will be possible under the heaviest band. In addition, strong winds gusting to 60 km/h are forecast to develop today and result in considerable blowing snow. Snow squall activity is expected to begin moving north of the region this evening.
Snow squalls cause weather conditions to vary considerably, changes from clear skies to heavy snow within just a few kilometres are common. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. Be prepared to adjust your driving with changing road conditions. Consider postponing non-essential travel until conditions improve. Public Safety Canada encourages everyone to make an emergency plan and get an emergency kit with drinking water, food, medicine, a first-aid kit and a flashlight.

Snow Squall Warnings are issued when bands of snow form that produce intense accumulating snow or near zero visibilities.
