Avalanche Summary
Solar induced avalanche activity tapered off over the past couple days as temperatures cooled slightly. Previous activity included loose wet sluffs up to size 2 on steep sun-exposed slopes. Cornices and glide cracks continue to fail with some regularity.
Snowpack Summary
Light new snow will bury a variety or old snow surfaces including a melt-freeze crust, moist snow, sugary facets, and wind affected snow. Pockets of wind slab could develop in exposed lee terrain over the next several days. 30 - 60 cm of snow overlies a crust, old wind slabs or surface hoar layer buried on March 9th. The distribution of the surface hoar is also highly variable and it does not exist in every drainage. I would still remain cautious and continue to dig and test before diving into my line. Deeper in the snowpack, basal facets may resurface as a concern with continued mild temperatures.Cornices have become well-developed and could easily become unstable during periods of warm weather or direct solar radiation.
