Avalanche Summary

No slab avalanches have been reported in the past 4 days. Skier triggered dry loose avalanches in steep terrain continue to be reported.

Snowpack Summary

Around 5 cm of new snow has fallen with moderate southerly wind, forming new wind slab on north aspects. In sheltered terrain this new snow may overlie soft, faceted snow or surface hoar. In exposed terrain it will overlie a sun crust or wind-affected snow.

20 to 40 cm overlies a weak layer from late January. In most areas, it is a hard slippery crust, however, on shady, upper-elevation slopes, it may be faceted grains or surface hoar.

The mid and lower snowpack is strong and bonded.
