B.C. weather: Arctic outflow, extreme cold warnings issued for large swath of province

Weather warnings for cold temperatures are blanketing the middle section of B.C.

Issued by Environment Canada, extreme cold and arctic outflow warnings stretch from Whistler and North Vancouver Island to the North Coast and inland, including the Chilcotin and Peace River regions.

The warnings stem from an arctic airmass that’s currently parked over western Canada, with temperatures plunging well below seasonal averages.

“A strong ridge of high pressure over the B.C. Interior will continue to force arctic air out to the coast via valleys and inlets,” said Environment Canada.

Notably, though, there are no weather warnings for the Lower Mainland and Southern Interior, along with most of Vancouver Island.

Areas under an arctic outflow warning will see wind chill values of -20 or lower near the coast and wind chill values of -35 to -45 for inland sections.

“This cold airmass will remain in place until Friday afternoon, with the coldest wind chill values occurring during the overnight and morning hours,” said Environment Canada.
