Alerts for: Grey - Bruce

Watches

11:42 PM EST Monday 11 December 2017
Snow squall watch in effect for:

  • Owen Sound - Blue Mountains - Northern Grey County

Snow squalls are expected to develop. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow, and snow will quickly accumulate.

Conditions will become favourable for snow squalls on Tuesday afternoon in the wake of an Alberta Clipper and general snowfall tonight.

Snow amounts near 15 cm per 12 hours are possible in the strongest snow squalls Tuesday afternoon and Tuesday night.

Areas from near Barrie across Collingwood to Meaford have the largest chance of receiving snow squalls according to latest indications.

The Midland to Orillia areas will be near the northeastern edge of the lake effect snow bands in this case.

Snow squalls may continue into Wednesday.

Visibility may be suddenly reduced at times in heavy snow. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.

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.
