Snow and blowing snow continues tonight. What: Poor visibility in heavy snow and blowing snow. Snowfall amounts up to 10 cm with locally up to 15 cm possible. When: Continuing tonight. Additional information: An Alberta clipper will continue to track east across the region tonight bringing with it gusty winds and heavy snow, leading to hazardous travel conditions. Visibility may be suddenly reduced to near zero at times. Roads and walkways may be difficult to navigate due to accumulating snow.
