This morning, Environment Canada warned of 10 to 15 centimetres of snow across Metro Vancouver on Christmas Day.
It's caused by an "unstable air mass combined with frigid outflow winds" that will give rise to "convective snow over eastern Metro Vancouver and parts of the Fraser Valley".
It's expected to taper off by evening.
So what is convective snow, you might ask? It's more intense and comes in shorter durations.
This is what people are saying about the snowfall over social media.
