AVALANCHE DISCUSSION

Today’s avalanche hazard is MODERATE. Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully. Natural avalanches unlikely; human triggered avalanches possible.

We obviously have some crazy warm weather and precip working on our snowpack. We have a couple of weak layers in our snowpack. The surface hoar buried 1-2 feet and the recent storm snow interface. I think that the strong winds have hammered our snowpack long enough that there is little snow left for transport. All the SE aspects are stripped of snow.

Lisa will issue the advisory tomorrow morning at 7am. If you get out in the backcountry give us a call at 754-2369 or send us your observations using the button at the top of this page
