It’s going to be a messy Monday for Niagara Falls, Welland, St. Catharines, Grimsby, and Niagara Region.

A winter storm warning in effect for:


  • Niagara Falls
  • Welland
  • Southern Niagara Region
  • St. Catharines
  • Grimsby
  • Northern Niagara Region

Winter storm conditions are  expected to start Sunday night and into Monday.

Very heavy snow expected as total snowfall amounts of 25 to 40 cm by Monday night.

Peak snowfall rates of 2 to 5 cm per hour are possible Monday morning.

This will all start late this evening through Monday evening.

A low pressure system tracking south of the Great Lakes will bring significant snowfall to the region. Heavy snow will likely significantly impact the Monday morning commute. Local blowing snow is also possible Monday morning through the 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. Take frequent breaks and avoid strain when clearing snow.
