Weather
Clear and inverted. Rapid warming this morning in the higher terrain. Valleys did not warm until later in the afternoon, and only briefly. Moderate to strong northerly winds in the alpine were mixing down to valley bottoms by afternoon.
Snowpack
Winds were keeping the snowpack cool in the afternoon, but some surface melting was occurring, and crusts will likely form tonight on sunny aspects below about 11K
Avalanche
Lots of small loose snow activity as well as a few small slabs from steep road cuts on a variety of aspects. Some of these spilled into the inside lane. Several larger slabs spotted on west aspects
