Winter storm warning in effect for:
- Niagara Falls – Welland – Southern Niagara Region
- St. Catharines – Grimsby – Northern Niagara Region
A major winter storm is expected.
A deepening low pressure system will give heavy snow and blowing snow. The snow will begin Tuesday midday and intensify into the evening with the heaviest amounts of snow falling Tuesday night. Strong northeasterly winds will also give blowing snow especially in exposed areas and along the Lake Ontario shoreline due to gusts of 70 kilometres per hour.
About 2 to 5 centimeters can be expected Tuesday afternoon and then 10 to 20 centimeters during the night. As the wind shifts early Wednesday morning to northerly the snow will end. Regions near Lake Erie may also experience several hours of freezing rain especially Tuesday night. If the freezing rain stays to the south of Niagara then they may see the highest amounts of snow.
Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow. There may be a significant impact on rush hour traffic in urban areas.
Winter storm warnings are issued when multiple types of severe winter weather are expected to occur together.
Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to storm.ontario@ec.gc.ca or tweet reports to #ONStorm.


This type of Winter storm often has a swath of 15 to 30 cm of heavy snow associated with it. The heavier bands of snow will begin in the Windsor to London area Tuesday afternoon and moving towards Toronto in the early evening. Freezing rain and ice pellets may also be a problem near the Niagara region. Exact snowfall amounts and the possibility of ice pellets and freezing rain will depend upon the exact track of this developing storm.
