Some post-secondary schools in B.C. have moved to online learning Tuesday as snow continues to batter the Lower Mainland.

A blanket has fallen across Vancouver, but its thickness varies Environment Canada Philippe-Alain Bergeron meteorologist tells V.I.A. So far only 3 cm has fallen at Vancouver's airport, but there's been an unofficial measurement of 9 cm downtown, and 15 cm measured in West Vancouver.

Parts of the Howe Sound and Fraser Valley will feel dramatically colder. Arctic outflow warnings have been issued for these areas, as powerful winds make temperatures feel as cold as -20 C. "Frostbite and hypothermia can occur within minutes if adequate precautions are not taken when outdoors," advises Environment Canada.

Temperatures already several degrees below seasonal averages will feel significantly colder, with parts of the Fraser Valley and eastern Metro Vancouver experiencing -20 C windchill. Temperatures at Vancouver International Airport (YVR) could feel as cold as -10 C or lower.

Metro Vancouverites should enjoy a drying trend following this week's snowstorm but another one could be on the way. Environment Canada Meteorologist Alyssa Charbonneau tells V.I.A. that the snowfall is expected to wane in the Lower Mainland after Wednesday, Feb. 5 as a moist Pacific system weakens.

While snow days don’t happen often in Metro Vancouver, it’s still a challenge for parents who need to make last-minute child care arrangements — but a pleasant surprise for kids hoping to fit in a day of snow fun.
