Good evening. This is Evelyn Lees with the
Slowly but surely, the snowpack is becoming closer and closer to good corn. Below freezing temperatures are forecast for the next few nights and daytime highs should be in the upper 30s to near 50s. This will create good supportable crusts each night, though they may soften at widely varying times each day depending on cloud cover and temperatures.
Some tips for weekend touring:
the most consistent conditions, corn snow, will be on east, south and west
facing slopes; plan your tour to stay mostly in the upper elevations the meager
mid and low elevation snow pack is vanishing rapidly; and choose a tour with a
good choice of sunny aspects, so you can work the slopes as they soften. The northerly facing slopes do have a few pa
The snowpack is mostly stable, and the danger of avalanches is generally low early in the morning. As the snow heats up each day, the danger of damp, loose sluffs on steep slopes of all aspects increases, especially sunny slopes. The first signs will be roller balls or the ability to push the snow and start sluffs with aggressive slope cuts. If the snow continues to heat, spontaneous sluffs may be possible. While not large, you definitely want to avoid being caught and carried over a cliff by one of these sluffs, or pushed into a gully and buried. There may also be a few fresh wind drifts along the highest ridges that could be sensitive to the weight of a person on a steep slope. There continues to be some collapsing of the crusts into the damp, loose snow below, but for the time being, these are very shallow.
For tonight and Saturday, the avalanche danger is generally LOW. With daytime heating, the danger may rise to MODERATE on steep slopes. On Sunday, the avalanche conditions will be very similar.
