Snow along with mixed snow and rain is being reported across much of Metro Vancouver a few hours after Environment Canada issued warnings for much of B.C.'s South Coast.
The forecaster expects between 10 and 15 centimetres of snow to fall through Wednesday morning.
Images and video of snowfall began appearing on social media after 8 p.m. PT Tuesday night.
"Be prepared for a snowy return to work for many," said CBC meteorologist Johanna Wagstaffe.
She said areas at elevations above 200 metres are most likely to see snow buildup.
Environment Canada said temperatures across most of Vancouver Island should stay warm enough to prevent significant accumulation of snow, with the exception of the higher elevations.
Up to 20 centimetres of snow is also forecast for Interior mountains near the Alberta border.
