Snow Squall Warning (Pukaskwa to Searchmont)

Dec 5, 2017 @ 08:12

5:29 AM EST Tuesday 05 December 2017
Snow squall warning in effect for:

  • Wawa – Pukaskwa Park
  • White River – Dubreuilville
  • Agawa – Lake Superior Park
  • Searchmont – Montreal River Harbour – Batchawana Bay

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 are expected to develop quickly this morning as ever colder arctic air blasts in from Lake Superior in the wake of a sharp cold front.

Snowfall amounts of 15 cm are expected in the heaviest snow squalls today into this evening.

Strong and gusty winds will frequently cause white out conditions in blowing snow, especially in exposed areas near Lake Superior.

Snow squalls are expected to drift southward out of the region this evening.

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. Rapidly accumulating snow could make travel difficult over some locations. Road closures are possible.

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