Lake effect snow squalls off Lake Superior are expected to develop this evening.

Local snowfall amounts of 15 cm are expected under the heaviest snow squalls.

Highway 17 is likely to be affected.

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. Rapidly accumulating snow could make travel difficult over some locations.

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