Snow squall warning in effect for:

  • Port Carling – Port Severn
  • Town of Parry Sound – Rosseau – Killbear Park

Snow squalls today and Thursday.

A heavy lake effect snow band off Georgian Bay is affecting areas near MacTier early this morning. Travel along Highway 400 is likely hazardous. This band of snow is expected to slowly lift northward and weaken later this morning.

However, lake effect snow is expected to reintensify later today near Georgian Bay due to increasing southwesterly winds ahead of an approaching trough. The activity should slowly shift southward during the day Thursday as winds become more northwesterly with the passage of the trough.

Some areas may see accumulations exceeding 15 cm by late in the day Thursday.

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

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@canada.ca or tweet reports using #ONStorm.

Snow squall watch in effect for:

  • Bracebridge – Gravenhurst
  • Huntsville – Baysville

Snow squalls possible today and Thursday.

Lake effect flurries off Lake Huron and Georgian Bay are expected to intensify later today due to increasing southwesterly winds ahead of an approaching trough. The activity should slowly shift southward during the day Thursday as winds become more northwesterly with the passage of the trough.

The snow squall activity is not expected to be particularly organized which will help to limit accumulations somewhat. However, some areas may see in excess of 15 cm by late in the day Thursday.

Travel may be hazardous due to sudden changes in the weather. 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.
