Snow and extreme wind are increasing the danger. Conservative terrain travel is recommended.
Extreme wind and new snow will rapidly form wind slabs in lee terrain features. Storm slabs may also form in areas sheltered from the wind.
THURSDAY NIGHT: Cloudy with snowfall, accumulation 5 to 10 cm, 40 km/h south wind, alpine temperature -5 C.
FRIDAY: Cloudy with snowfall, accumulation 10 to 20 cm, 80 to 100 km/h southwest wind, alpine temperature -4 C.
SATURDAY: Cloudy with snowfall, accumulation 10 to 20 cm, 60 km/h south wind, alpine temperature -1 C, freezing level 1400 m.
SUNDAY: Cloudy with snowfall, accumulation 5 cm, 30 km/h southwest wind, alpine temperature -6 C.
No recent avalanches were observed. Avalanche activity is expected to ramp up on Friday during the storm. Natural and rider-triggered avalanches will be likely.
We appreciate all your observations on the Mountain Information Network.
We are in the midst of a strong storm that will impact the region for the coming days. We are expecting around 20 to 30 cm of snow to accumulate at White Pass by sunset on Friday, with extreme southwest wind. Wind slabs will likely rapidly form in wind-exposed terrain and storm slabs in sheltered terrain.
The remainder of the snowpack is hard but heavily faceted.
