Small new windslabs may form with strong SW winds throughout the forecast period. Triggering a persistent slab may be possible in isolated areas and may be more reactive if moisture penetrates down to this layer from rain or temps above zero.

Confidence

Moderate

Snowpack Summary

Small wind slabs forming in the Alpine with Strong SW winds. Below 2000m there is moist surface snow which will refreeze with cooling temps. The Dec 23 Melt Freeze Crust and Facets are down 40-100 cm. An early season basal crust complex exists most places in the alpine and at treeline. Significantly less snow in the eastern areas of the park. Snowpack depths between 30 - 170 cm.
