Another 10 to 15cm Expected

0

Persistent 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 squalls off Lake Superior are expected to affect the area from just north of Montreal River to Sault Ste Mare this evening and tonight. The squalls will end over the Montreal River area overnight, but will persist near the Sault until around noon Thursday.

The heaviest squalls could produce snowfall amounts of 10 to 15 cm per 12 hours along with near zero visibilities in blowing snow.

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. 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.
