After weeks of above-average temperatures, an arctic outflow warning is in effect for Whistler on Thursday.
According to Environment Canada, temperatures could plummet to as low as -30 C with the wind chill in the coming days.
"Arctic air combined with strong outflow winds will generate wind chill values of minus 20 to minus 30 beginning on Thursday night," reads the warning.
"Wind chill values may moderate on Saturday afternoon but uncertainty remains on the timing of the warm-up. Frostbite and hypothermia can occur within minutes if adequate precautions are not taken when outdoors. Any skin exposure will result in frostbite. If outside, dress warmly in layers and stay dry. Cover as much exposed skin as possible to avoid frostbite."
The Whistler Community Services Society will open its extreme weather shelter on Jan. 11, 12, 13 and 14. Find them at 8000 Nesters Road if you need warm shelter from 6 p.m. to 8 a.m. on those dates.
