Environment Canada has issued a snow squall warning for Sault Ste. Marie today with as much as 15 cm expected by Monday night.
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.
Snow squall warning in effect for:
Agawa – Lake Superior Park
Sault Ste. Marie – St. Joseph Island
Searchmont – Montreal River Harbour – Batchawana Bay
In the wake of a low pressure system, a cold west to northwest flow over Lake Superior is producing multiple snow squalls that are affecting areas from Batchawana Bay to Lake Superior Provincial Park. The squalls are expected to shift south into the Sault Ste. Marie area later this morning and out of the Lake Superior Provinicial Park area near midday. All the snow squalls are expected to weaken this evening.
The heaviest squalls may produce 10 to 15 cm per 12 hours along with very low visibilities in bursts of heavy snow and local blowing snow.
Driving conditions will quickly deteriorate tonight and become hazardous due to very low to possibly nil visibility in the snow squalls. Motorists should consider changing travel plans as necessary.
Snow squalls cause weather conditions to vary considerably, changes from clear skies to heavy snow within just a few kilometres are common. Be prepared to adjust your driving with changing road conditions. Consider postponing non-essential travel until conditions improve.
Snow Squall Warnings are issued when bands of snow form that produce intense accumulating snow or near zero visibilities.
