Bundle up, folks. Environment Canada has issued an arctic outflow warning for Metro Vancouver, warning of frigid wind chill values.

The weather agency says the “first Arctic intrusion of the year is on the horizon” as we head into Thursday.

“Arctic air combined with strong outflow winds gusting to 60 km/h will generate wind chill values of minus 20 beginning on Thursday night,” says Environment Canada.

The wind chill values may moderate on Saturday, but the exact timing remains uncertain. The frigid temperatures increase the risk of frostbite and hypothermia.

“If outside, dress warmly in layers and stay dry. Cover as much exposed skin as possible to avoid frostbite.”

Along with the freezing temperatures, there is a 40% chance of flurries Thursday with more snow in the forecast for the evening hours.
