In a weather advisory issued on Friday, the agency said a frontal system currently developing over the Pacific is set to approach the BC Coast this weekend, reaching Vancouver Island on Sunday.
As a result, a “ridge of high pressure will remain over the BC Interior into at least next week, spilling dry arctic air into the Georgia Basin. Around the South Coast, daytime highs will struggle to rise above the freezing mark.”
What this means, at least for the moment, is that snow is expected to develop across Vancouver Island during the day on Sunday and spread to the mainland coast Christmas Eve.
Arctic outflow conditions could combine with this system and produce heavier snowfall in areas along the eastern side of the island as well.
Snowfall amounts are uncertain at this point but the prospect for appreciable accumulations lies with Vancouver Island. On the mainland side, lower amounts are possible.
As a result, those travelling through the region over the next few days, especially on Christmas Eve, are encouraged to monitor forecasts and statements for updates.
