Weather Forecast

Overnight: Continued flurries. Accumulation: 10 to 14 cm. Alpine temperature: High -3 °C. Ridge wind south: 15-35 km/h. Freezing level: 1800m.

Tuesday: Cloudy with sunny periods and isolated flurries. Risk of a thundershower? Precipitation: Trace. Alpine temperature: High -4 °C. Mostly light ridge wind occasionally gusting to 45 km/h.

Snowpack Summary

Up to a total of 30cm of storm snow accumulated by Tuesday morning. Expect to find new wind slab on lee ridge-top features and below. The new snow will overlie previously wind affected surfaces in non-sheltered areas in the alpine and below as well as widespread surface facets. Strong mid-pack in deeper areas overlies supportive basal layers.

Avalanche Summary

Patrol teams reporting variable snowfall through the forecast region. Poor visibility and no new avalanche activity reported or observed.
