Points saillants

Natural activity may increase Sunday, as new snow and warm temps continue to build fresh storm slabs.

Minimize your exposure to overhead hazard, especially during periods of heavy snowfall or rapid loading from wind.

    Snowfall, warm temps, and strong SW winds continue to build fresh storm slabs. These will be most sensitive to triggering where they overlie surface hoar and/or a sun crust (from the recent inversion).

Confidence

Moderate

  • Forecast snowfall amounts are uncertain.

Avalanche Summary

A few small loose snow avalanches were observed in the steep terrain above the highway corridor on Saturday.

On Wednesday and Thursday, a temperature inversion and solar inputs above valley cloud, triggered loose wet avalanches in steep South facing terrain up to size 1.

Snowpack Summary

Up to 35cm of storm snow is forecast to have accumulated by the end of day Sunday. This is burying a mix of surface hoar size 3-8 mm (most prevalent just below treeline on shaded slopes), a breakable sun crust on steep solar slopes at upper elevations (formed by a temperature inversion), and wind effect in open terrain.

The mid and lower snowpack are well settled and right side up.

Weather Summary

Snowfall continues Sunday, bringing weekend storm snow totals of up to 40 cm by the end of day.

Tonight Snow (5-10cm). Alpine Low: -6°C. Freezing level (FZL) 1200m. Moderate Southerly Ridgetop winds.

Sun Flurries (5-10cm). Alpine High -3 °C. FZL 1600m. Moderate gusting strong SW wind.

Mon Flurries (5-10cm). Alpine Low -13 °C, High -8 °C. Moderate SW wind.

Tue Flurries. Low -12 °C, High -10 °C. Moderate SW wind.

Terrain and Travel Advice

  • Carefully manage your exposure to overhead hazards.
  • Don't let the desire for deep powder pull you into high consequence terrain.
