Lo esencial

5-15 cm of new snow and moderate to strong westerly winds have formed fresh wind slabs reactive to human triggers. Use caution around lee terrain features and steep, convex slopes.

Avalanche Summary

No new avalanches were reported in this region on Saturday.On Friday, a snowmobiler was buried in a size 2.5 wind slab avalanche on a north facing aspect at 2200 m. near the Blowdown cabin. Check out the MIN report HERE.

Snowpack Summary

Currently, the snowpack structure changes dramatically with elevation and aspect. 10-20 cm. of recent storm snow (amounts tapering with elevation) is sitting on a melt/freeze crust, except for north facing terrain above 2000 m. where the old snow surface remained dry and small surface hoar (weak, feathery crystals) may be present in isolated locations. This recent snow has been affected by the sun and re-distributed by southerly winds, forming wind slabs on lee features below ridgetops.Below roughly 1900 m, the snowpack is moist and is melting rapidly at lower elevations.
