Details

A deepening Arctic airmass combining with moisture from an upper disturbance southwest of Vancouver Island is producing strong winds. Winds of 60 to 70 gusting to 90 km/h are combining with the cold temperatures to give wind chill values down to minus 20 degrees over the central coast and over the inland sections of the north coast. These conditions will spread to the Howe Sound Whistler and Fraser Valley area throughout the afternoon as temperatures drop and winds increase. Meanwhile snowfall amounts of 5 to 10 cm have already fallen across parts of Southern Vancouver island with as much as 15 cm at Port Alberni. A further 5 to 10 cm is possible before snow eases off later this afternoon.
