Snow squall warning in effect for:
Agawa – Lake Superior Park
Sault Ste. Marie – St. Joseph Island
Searchmont – Montreal River Harbour – Batchawana Bay
Snow squalls beginning this afternoon.
Hazards:
Local snowfall accumulations of 20 to 35 cm by Thursday morning.
Westerly winds gusting 70 to 80 km/h, and possibly even 90 km/h, are expected this afternoon through Thursday morning resulting in extensive blowing snow and significantly reduced visibility.
Timing:
This afternoon through Thursday morning.
Discussion:
Snow squalls off Lake Superior will develop this afternoon and continue through Thursday morning. Gusty westerly winds will make for extensive blowing snow and near zero visibility at times. Dangerous travel conditions are expected along Highway 17.
Strong winds will gradually diminish and snow squalls will taper to flurries through Thursday morning.
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. Consider postponing non-essential travel until conditions improve. Road closures are possible.
