Lo esencial

The snow is light and skiing is good, but keep in mind that the snow is still settling after a recent load of 50 cm. Whoomphing and cracking means it's time to ski lower angle slopes.

Keep an eye out for signs of wind effect. The same light snow which is good for skiing is also ideal for wind transport.

    As the wind picks up at upper elevations, reactive windslabs may form in lee features.

    A faceted weak layer exists under a thin crust in isolated pockets. Depending on wind transport over the next few days, this layer could become active. We have had consistent easy propagating test results on this layer on northly aspects.

Confidence

Moderate

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

Avalanche Summary

Numerous dry loose avalanches to size 1.5 were observed on Thursday as the sun came out and visibility improved. These likely ran during the storm Tues-Wed or as the sun came out Thursday.

Snowpack Summary

Another 20 cm has fallen on top of the 20-30 cm we received over this past weekend. This snow is light density and unconsolidated but is settling.

Under this, on polar aspects there are a series of melt freeze crusts and faceted layers. While on solar aspects, these layers have combined to form a singular thick melt freeze crust.

The mid and lower snowpack is well settled.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
