Winter Storm alert upgraded to a Warning with 15 to 30 cm expected.
Major winter storm beginning this evening with heavy snow and blowing snow.
Rain is expected to develop this afternoon as a strengthening low pressure system approaches the Great Lake tonight.
As the low approaches, increasing northeasterly winds will pull in colder air from the north. This will result in the rain quickly changing to snow by evening. The snow will persist through the night and may fall heavily at times. Northeast winds gusting to 60 km/h will also result in areas of blowing snow giving very poor visibility at times tonight into Friday morning. Travel tonight is not advised.
Total snowfall accumulations of 15 to 30 cm are likely by the time the snow tapers off late Friday morning.
Although the worst of the conditions are expected tonight, the Friday morning commute will likely be significantly impacted as well.
###
Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.
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 ec.cpio-tempetes-ospc-storms.ec@canada.ca or tweet reports using #ONStorm.
