ENVIRONMENT Canada has issued an alert for Metro Vancouver:  Cold Arctic currently over the northern BC interior will continue to filter southwards and towards the BC coast. The Arctic air will arrive in the southern interior overnight or early Monday morning and reach the south coast Monday morning.

On Tuesday, temperatures will continue to drop as more Arctic air is forced southwards. Strong outflow winds and brisk wind chill values are then expected to begin over southern coastal areas Tuesday night.

Temperatures over Interior regions will be 10 to 20 degrees below the seasonal average, while coastal areas will be 5 to 10 degrees below seasonal, making for the coldest conditions seen this season.

The cold air will persist for the remainder of the week.

Arctic Outflow and Extreme Cold warnings are in effect for several regions in the province and may be expanded as the Arctic air progresses.
