EC – Snow Squall Watches and Warnings

Mar 8, 2017 @ 04:52

3:25 AM EST Wednesday 08 March 2017
Snow squall warning in effect for:

• Wawa – Pukaskwa Park
• White River – Dubreuilville
• Agawa – Lake Superior Park

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.

Snow squalls have developed over the area and are expected to continue through this afternoon. Snowfall accumulations of 15 cm per 12 hours are possible.

The snow squalls will weaken late this afternoon.

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. Travel is expected to be hazardous due to reduced visibility in some locations. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop.

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

3:32 AM EST Wednesday 08 March 2017
Snow squall watch in effect for:

• Searchmont – Montreal River Harbour – Batchawana Bay

Persistent 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.

Snow squalls are expected to develop this morning and will continue into Thursday morning.

Snowfall accumulations of 15 cm per 12 hours are possible under the heaviest snow squalls. The snow squalls will begin to weaken Thursday morning.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel may be hazardous due to sudden changes in the weather. Visibility may be suddenly reduced at times in heavy 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.
