Lo esencial

More snow, wind, and sun. Keep an eye out for new wind slab formation, beginning during Monday's storm. Dry loose avalanches could be a problem on Tuesday, as the storm snow sees solar radiation for the first time.

    Though there may be some lingering wind slabs in the alpine (from the previous storm cycle), this problem will be the most prevalent where new wind slabs have formed due to Monday's snow and winds.

    Look out for solar triggered dry loose avalanches as Monday's unconsolidated snowfall is expected to see solar radiation for the first time on Tuesday.

Confidence

Moderate

  • We are uncertain due to the timing, track, and intensity of the incoming weather system.

Avalanche Summary

Several wet loose avalanches up to size 1 have been observed from the most recent warming.

Snowpack Summary

The current storm snow falls on a widespread melt freeze crust. This crust is present at all aspects and elevations except polars in the high alpine (where there is a 10-30 cm thick wind slab on some slopes). Under the crust is moist snow that is slowly refreezing. The mid and lower snowpack is well settled.

Weather Summary

Up to 11 cm of snow. Alpine Low of -5 °C, High of -5 °C. W wind gusting to 45 km/h. Freezing level at valley bottom.

Terrain and Travel Advice

  • 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.
