Winter storm watch in effect for:
- Niagara Falls – Welland – Southern Niagara Region
- St. Catharines – Grimsby – Northern Niagara Region
A snow storm is looking more likely for Southern Ontario Tuesday and Tuesday night.
A low pressure system developing over Texas today will head towards the Lower Great Lakes and is expected to spread an area of snow into Southern Ontario Tuesday and Tuesday night. This low will tap into moisture from the Gulf of Mexico and has the potential to intensify into a significant winter storm.
This type of Winter storm often has a swath of 15 to 30 cm of heavy snow associated with it. Freezing rain and ice pellets may also be a problem as the storm centre gets close to the Lower Great Lakes. Exact snowfall amounts and the possibility of ice pellets and freezing rain will depend upon the exact track of this developing storm.
Travellers should be prepared to alter plans accordingly as driving conditions are likely to deteriorate significantly on Tuesday.
The development and track of this storm is being monitored closely. Please refer to updated statements and local forecasts for further details as the event approaches.
Rapidly accumulating snow could make travel difficult over some locations. Visibility may be suddenly reduced at times in heavy snow. Poor weather conditions may contribute to transportation delays. There may be a significant impact on rush hour traffic in urban areas.
Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to firstname.lastname@example.org or tweet reports to #ONStorm.
