Snow squalls off Lake Superior expected to return tonight. What: Significantly reduced visibility in heavy snow and blowing snow. Local snowfall amounts near 10 cm. When: Returning tonight and ending Wednesday morning. Additional information: The lake effect snow squalls return tonight. The main concern will be low visibilities due the intense snowfall rates and localized blowing snow. The bulk of the accumulation is expected to occur for areas near the Lake Superior shore. The snow squalls will ease Wednesday morning. ### Travel will likely be hazardous. Visibility will likely be suddenly reduced to near zero at times. 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. For more information about the alerting program, please visit: https://www.canada.ca/en/services/environment/weather/severeweather/weather-alerts/colour-coded-alerts.

Prepare for quickly changing and deteriorating travel conditions. Consider postponing non-essential travel and outdoor activities until conditions improve.
