Environment Canada has issued multiple watches, warnings and statements regarding winter weather that could impact parts of Southern Ontario today. Here are the details:

4:39 AM EST Thursday 06 December 2018
Weather advisory in effect for:

  • Niagara Falls – Welland – Southern Niagara Region
  • Catharines – Grimsby – Northern Niagara Region
  • Dunnville – Caledonia – Haldimand

Winter Weather Travel Advisory in effect this morning and afternoon. A band of lake effect snow is affecting portions of eastern Lake Erie early this morning. Latest analysis is suggesting that this band will slowly lift northward through the morning to reach northern Niagara by late morning. This band is then expected to shift back south in the afternoon and out of the region by evening.
Southern Niagara will likely be impacted the most with 10 to 15 cm possible in areas that receive the most persistent snowfall. Northern Niagara will likely see considerably less accumulation. Travel today will likely be hazardous at times. In addition, gusty winds may result in areas of blowing snow and poor visibility.

 

4:24 AM EST Thursday 06 December 2018
Snow squall watch in effect for:

  • Barrie – Collingwood – Hillsdale
  • Innisfil – New Tecumseth – Angus
  • Goderich – Bluewater – Southern Huron County
  • Listowel – Milverton – Northern Perth County
  • Stratford – Mitchell – Southern Perth County
  • Wingham – Blyth – Northern Huron County

Snow squalls likely tonight. Some light snowfall is expected to affect areas southeast of Georgian Bay today in association with an approaching cold front. The snow should intensify this evening as winds become more northwesterly with the passage of the cold front. The snow squall activity should weaken Friday morning. Some areas may see snowfall accumulations in excess of 15 cm by Friday. 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.

 

4:28 AM EST Thursday 06 December 2018
Snow squall warning in effect for:

  • Bruce Peninsula – Sauble Beach – Tobermory
  • Owen Sound – Blue Mountains – Northern Grey County
  • Bracebridge – Gravenhurst
  • Huntsville – Baysville
  • Port Carling – Port Severn
  • Town of Parry Sound – Rosseau – Killbear Park

Snow squalls continuing today. Snow squalls are affecting areas east of Georgian Bay early this morning. For the most part, the activity is rather disorganized, but occasional bursts of heavy snowfall along with very poor visibility can be expected. The activity should slowly shift southward during the day as winds become more northwesterly behind a passing cold front.

Some areas may see accumulations exceeding 15 cm by later today. 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. Be prepared to adjust your driving with changing road conditions.
