Snow Squall Warning

Issued at 19:39 Tuesday 12 December 2017

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.

Lake effect snow squalls are expected to persist through tonight.

Snowfall amounts near 15 cm per 12 hours are likely in the strongest snow squalls. Local blowing snow is also possible leading to reduced visibilities.

Snow squalls will begin to ease Wednesday 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. Road closures are possible.

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.
