Kernpunkte

Our deep persistent slab is still a concern, continue to avoid thick to thin areas while recreating.

Be mindful of the daytime warming of the snowpack as temperatures are not forecast to cool off significantly Friday night.

    Continue to pay attention to the weak basal facet layer in areas where the snowpack is shallow (<2 m) such as moraines or wind-scoured areas, or in places with large triggers like cornices that could impact the slope.

Snowpack Summary

Warm temperatures have likely formed a new crust on all aspects up to tree line. Isolated wind slabs sit on sun crusts to ridge top and temperature crusts below 1500m. The mid-pack in this area is generally strong, although the base of the snowpack consists of weak facets in thin areas (<2 m).

Confidence

Moderate

Avalanche Summary

No new natural activity. Explosive work at ski hills producing size 1-1.5 wind slabs out of extreme terrain.

Weather Summary

Saturday: Scattered flurries will bring light snowfall to the region.

Ridgetop winds will be from the southwest near 40-50 km/h and freezing levels forecast to hit 2000m. The alpine high should range between 0C and +5C.

Sunday: Winds and temperatures will rise significantly through the day. Freezing levels are forecast to hit between 2300m-2700m and winds will push up into the strong/extreme range out of the south west. The snow/rain will start Sunday evening.
