Snow squalls are expected. What: Total snowfall accumulations of 20 to 40 cm, with the highest amounts expected if a snow squall locks into place over a particular region. Significantly reduced visibility in heavy snow. When: Late this afternoon through Monday morning. Additional information: Lake effect snow will develop off of Lake Huron beginning late this afternoon. A snow squall band is expected to form late in the day and last through the night. The exact positioning of this snow squall band is uncertain at this time and therefore the location of the greatest snowfall totals. ### Visibility may be suddenly reduced to near zero at times. Road closures are possible. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or post reports on X using #ONStorm.

Prepare for the possibility of quickly changing and deteriorating travel conditions.
