In sintesi

The avalanche danger remains CONSIDERABLE on steep, upper elevation, northerly facing slopes. In these areas, slabs have formed on top of layers of weak, sugary, faceted snow. This persistent weak layer problem will be with us for the foreseeable future and though overall low coverage makes it difficult to access these areas, steep, northerly facing slopes should be avoided. There is a MODERATE avalanche danger on steep slopes at upper elevations that have recent deposits of wind drifted snow. Most other terrain has generally LOW danger.

Snow and Weather

Although an active weather pattern will bring a series of storms to the north throughout the upcoming week, the desert southwest, and particularly our mountain range will remain dry. Long-range models however are now hinting at developing moisture early next week. Look for mostly sunny skies today with light northwesterly winds shifting to the SW later today. High temps will be in the upper 20's.

Snowpack Discussion

The existing snow structure is very poor. Recent and wind drifted snow overly a layer of weak, sugary, faceted snow creating a persistent weak layer problem. In our travels Friday, we observed widespread cracking and collapsing of the snowpack. These are clear red flag signs of instability. Human triggered avalanches remain likely on steep, northerly facing slopes above about 10,000'. Overall coverage remains quite thin and there really isn't enough snow for much off-trail recreation.

This video of an extended column test illustrates the persistent weak layer problem. The slab on top slides off of the layer of sugary, faceted snow underneath.
