Snow Squall Warning

Issued at 04:45 Saturday 16 December 2017

Snow squalls have developed to the southeast of Georgian Bay. Snowfall rates of several centimetres per hour are possible in bursts of heavy snow.

Total snowfall amounts of 15 to 20 cm are likely before the snow squalls end later this morning.

Strong and gusty winds will result in occasional blowing snow this morning.


Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel is expected to be hazardous due to reduced visibility in some locations.

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

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports using #ONStorm.
