No specific avalanche problems exist at this time. Normal caution tactics and companion rescue gear are advised for any travel in avalanche terrain today. Anticipate encountering lots of obstacles buried shallow in the snowpack. Slowing down and sticking to conservative route choices will help you avoid hitting them. Conditions right now are pretty good for practicing companion rescue.

Snowpit data and other field observations indicate that avalanches are unlikely at this time. The existing snowpack is shallow but supportable for over snow travel. Numerous obstacles such as rocks, logs, etc are usually easily avoidable with a little care (i.e. slower speeds and conservative route choices). In areas protected from wind and sun, faceting processes are at work, especially on the upper portion of the snowpack. In sun exposed areas melt-freeze has affected the snow surface. In wind exposed areas, some scouring has occurred with rough (sastrugi) and sometimes firm snow surface conditions. Historically, some of our most problematic weak layers tend to form during dry spells such as the current one, so snowpack monitoring remains ongoing.

Weather and CURRENT CONDITIONS
weather summary

High pressure is in place over the forecast area. Air temperature inversion conditions have the coldest air on the mountain valley floors this morning rather than at the mid and upper elevations. Mainly light winds are forecast for today with the occasional moderate gust this afternoon. SW winds increase tonight and tomorrow ahead of an approaching dry cold front. This increase in winds is expected to mix out inversion conditions for increased warming at the low and mid elevations tomorrow. A slight cool down and a shift back to NE winds are forecast for Tuesday.
