Winds continued from the southwest during yesterday's snowfall, creating areas with dangerous avalanche conditions at upper and mid elevations... Triggered wind slab avalanches one to two feet deep are likely on drifted upper and mid elevation slopes. Watch for and avoid stiffer fresh wind slabs on the lee side of major ridges and in and around terrain features like cliff bands, sub-ridges, gullies, and scoops. Potential wind slabs are drifts that often appear smooth or rounded and chalky looking, and they sometimes sound rather hollow. Cracking and audible collapsing are red flags, and reevaluation of your route is recommended if you encounter these conditions.

In many areas yesterday's heavy snow is not sticking well to the weak snow that was on the surface during the recent prolonged high pressure system. The preexisting snow on shady mid elevation slopes is especially weak, and triggered soft slab avalanches are likely on steep slopes with more than a couple inches of heavy new snow and possible at all elevations....

Wet avalanches at lower elevations created quite a problem yesterday in the mountains to our south. Temperatures stayed a little cooler up north, but lower elevation snow that has been kept very cold by the long lasting temperature inversion is warming significantly and becoming saturated. If temperatures rise further than expected at lower elevations today, wet avalanches will become likely on steep slopes. Avoid steep lower elevation slopes with saturated snow and stay clear of potential terrain traps like gullies, creek beds, or trees below.
