Winter storm warning in effect for:

  • Newmarket - Georgina - Northern York Region
  • Pickering - Oshawa - Southern Durham Region
  • Uxbridge - Beaverton - Northern Durham Region
  • Vaughan - Richmond Hill - Markham

Winter storm conditions continue.

Total snowfall amounts of 25 to 35 cm.
Snow, at times heavy, with peak snowfall rates of 4 to 6 cm per hour possible this morning, which will significantly reduce visibilities.
Local blowing snow at times due to winds gusting up to 60 km/h.

When: Now through this evening.

Discussion: A low pressure system tracking south of the Great Lakes will bring significant snowfall to the region. Heavy snow will significantly impact the commute this morning. Local blowing snow is also possible this afternoon and evening with gusty northerly to northwesterly winds.


Consider postponing non-essential travel until conditions improve. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow. Visibility may be suddenly reduced at times in heavy snow. There may be a significant impact on rush hour traffic in urban areas.
