Alerts in Effect
Snow Squall WatchIssued at 15:27 Tuesday 21 November 2017
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 are favourable for a period of lake effect snow squalls off Lake Huron beginning after midnight tonight into Wednesday.
Snowfall amounts may reach 10 to 15 cm by Wednesday afternoon where snow squall bands linger. Northwest winds gusting up to 60 km/h will reduce visibilities in blowing snow.
Environment and Climate Change Canada is monitoring the situation and will issue snow squall warnings as required.
Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel may be hazardous due to sudden changes in the weather. Visibility may be suddenly reduced at times in heavy snow.
