In sintesi

Low danger and generally stable snow persist.

Small inputs of snow and wind on Thursday and Friday may create a new windslab problem later in the week.

    This avalanche problem is only a "problem" in thin snowpack areas, mainly on the east side of Hwy 93 & Hwy 1, where facets persist near the ground.

    Triggering is unlikely, but the problem is inherently uncertain and may still be triggered in isolated, steep terrain with a thin-to-thick snowpack.

Confidence

High

  • We are uncertain whether the wind will be enough to form new wind slabs.

Avalanche Summary

No new avalanches observed or reported on Wednesday

Snowpack Summary

Extensive wind effect exists in the alpine, with some surface faceting helping to break down crusts and create softer skiing. In sheltered areas at treeline and below, widespread surface hoar was buried by a few centimetres on Saturday and is now the Jan 24 layer. A deeper surface hoar layer lies 50–60 cm down, but there have been no recent avalanches. Basal crust and/or facets exist in thin snowpack areas, but overall, this year's deeper snowpack is stronger than usual.

Weather Summary

Little change in the foreseeable future, although we may see some small accumulations of snow:
Thursday
Mostly cloudy. 1 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -6 °C.
Friday
Mostly cloudy. 2 to 3 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -5 °C.
Saturday
Mix of sun and clouds. 1 to 2 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -5 °C.

Terrain and Travel Advice

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
