Up to 10 cm of snowfall possible in parts of the Lower Mainland on Monday
Parts of the South Coast could see impactful snowfall on Monday as a low-pressure system from Alaska pushes southeast into the region, according to Environment and Climate Change Canada’s special weather statement on Sunday.
The federal government’s meteorological agency has issued a bulletin for Metro Vancouver, the western Fraser Valley including Abbotsford and Mission, Howe Sound, and the Sunshine Coast, warning that higher elevations in particular could receive five to 10 cm of snow between Monday morning and Monday night.
Light precipitation is expected to begin in the pre-dawn hours Monday. As a cold front sweeps across the region through the day, precipitation is forecast to become steadier, with snow developing over higher elevations before easing Monday night.
Forecasters say snow levels will fluctuate between about 400 and 100 metres, dropping even lower near the mountains. During heavier bursts, wet snow could mix in at lower elevations, and localized areas could see higher accumulations where more intense bands set up.
Behind the front, a colder and more unstable air mass is expected to settle over the South Coast from Tuesday through Thursday, bringing the chance of locally intense convective snow showers.
Based on Environment Canada’s Vancouver International Airport weather station, which is moderated by its location next to the sea, overnight lows are expected to hover just below or just above freezing, with daytime highs reaching up to 3°C on Monday and 5°C or 6°C for the rest of the week ahead of the weekend.
