市民请及时清理自家房屋前的道路冰雪。
When it snows, #Vancouver residents play a critical role in keeping sidewalks safe. But, snow and ice removal can be difficult for seniors and people with limited mobility. Become a snow angel today to help a neighbour in need 😇

An upper-level trough will push southward across the BC interior today causing an artic front to surge towards Southwestern BC sometime tonight into Sunday morning. Coastal low will set up south of Vancouver Island bringing a chance for wintry precipitation to the coast #BCStorm pic.twitter.com/D7gF4VHNhz
