Nothing new today.
Snowpack Summary
A few more centimeters fell last night. At the moment we have 15-20cm of new snow from the last few days. This is sitting on more snow from previous storms. Amazingly, the low elevation winds have been light enough lately to keep this new snow light and relatively slab free. The alpine has seen some isolated wind affect, but this is limited to the bigger, more exposed peaks and open slopes. Windslabs are the main concern right now. We're seeing them around the bottoms of large cliffs and isolated pockets near ridge lines. The weak basal layers are still there, and as unconsolidated as ever. What is saving us from a nightmare of a snowpack is the mid pack bridging effect. The mid pack has enough strength and depth that triggering the bottom layers is becoming more difficult. The key to avoiding trouble is avoiding thin areas where the bridging is minimal.
