Kernpunkte

Another storm is on the way, and it may be an upslope one. On polar aspects, keep an eye out for storm slabs caused by an "Upside down" setup.

On solars look out for dry loose activity Thursday and wet loose activity Friday and Saturday.

    On polar slopes, Monday's snowfall remains lighter density. The new storm is expected to bring warmer temperatures and we could see a classic "upside down" setup.

    Expect to see this problem Friday and Saturday, in areas with less cloud cover. There is the potential to see this problem in lower elevation bands during the storm if the freezing level is higher than forecasted.

Confidence

Moderate

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

Avalanche Summary

Numerous dry loose and several wet loose avalanches up to size 1 have been observed in the last 24 hours.

Snowpack Summary

The current storm snow is falling on top of 5-20 cm of well consolidated snow on solar aspects, and on polar aspects it is falling on 20-30 cm of lighter density snow. Under this, is a robust rain crust which is 20-50 cm thick. The lower snowpack is well settled and moist to ground tree line and below.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
