Snowpack Summary
We have had very little information about the snowpack in this region for several days now. However, I suspect the light snowfall with light winds at higher elevations has created a fairly consistent covering over a variety of old surfaces. These surfaces include well settled powder on steep north-facing slopes, and temperature-affected snow on solar aspects up high and on all aspects at lower elevations. I suspect below the snow line, rain is penetrating and weakening already wet snow. As we head deeper into spring, expect potentially potent, yet relatively short-lived, instabilities with each storm. Wet slabs and wet loose snow avalanches also remain a real possibility during periods of warming or direct solar radiation, especially if there is minimal amounts of overnight freeze. Expect cornices to be large and potentially unstable, especially under sunny skies.
