Snow Squall Watch

Issued at 20:55 Wednesday 13 December 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.

Lake effect snow squalls are expected to develop Thursday morning.

Snow squalls from Georgian bay will affect the regions early Thursday morning and will dissipate by Thursday evening. Local snowfall accumulations of 10 to 15 centimetres are possible.


Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common.

Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could 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.
