Avalanche Summary
No new avalanches have been reported this weekend with limited travel and visibility in the mountains. Please continue to post your observations and photos to the Mountain Information Network. It helps strengthen our data gathering.
Snowpack Summary
Up to 25 mm of wet snow is found at treeline and above, which sits over a melt-freeze crust down to 1200 m. The upper snowpack consists of moist snow overlying a few supportive crusts formed early January and late December. Below treeline, the snow surface is likely saturated.
Weather Summary
Overcast skies and dry conditions are expected until a deeper system will push heavier snowfalls into the region late evening Wednesday. This frontal system will lead a stalled atmospheric river over Coast Mountains through Friday night, bringing heavy precipitation and high freezing levels.
Tuesday night
Mainly clear, no precipitations, light southeasterly winds, freezing levels rising to 1500 m, low of -3C at treeline.
Wednesday
Increasing cloudiness, light snow up to 5 cm starting midday at higher elevations, rain at treeline and below, moderate southeasterly winds gusting 50 km/h, freezing levels around 1500 m, high of +2C at treeline.
Thursday
Stormy, 40-65 mm of rain, snow at upper elevation only, moderate southeasterly winds gusting 65 km/h, freezing levels around 2000 m, high of +4C at treeline.
Friday
Stormy, 50-70 mm of rain, snow at upper elevation only, moderate southeasterly winds gusting 65 km/h, freezing levels around 2000 m, high of +4C at treeline.
