Snowpack Summary
The December 23rd storm left 25-35 mm of precipitation in all forms: rain, sleet, snow. Below 650 m, 3-5 cm of low density snow overlie a crust formed by the December 23 refreeze cycle and rain. Above 650 m, the accumulations resulting from this weather bomb are highly variable. Sheltered slopes, have seen great accumulation of heavy snow. The alpine, exposed to the strong to extreme winds of the recent weather events, is generally back to crust or even bare ground. However, significant amounts of storm and windblown snow can be found in isolated areas on the N to E side.The average snowpack height is still very thin, averaging around 25 cm in the valley to 65 cm at mid-mountain.Despite the fresh snow supply, snow conditions remain hazardous. Crust and obstacles such as rocks, stumps, trees and trunks can still be found barely buried under this white blanket.

Terrain and Travel Advice
- Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
- Make observations and assess conditions continually as you travel.
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
Problems
Wind Slabs
Wind slabs of highly variable depths have developed on isolated features on northwest to east slopes due to sustained winds. Human intervention triggers are possible on wind loaded and cross loaded features. Lack of snow in the area may give you very little information and no signs of instability. However, if you see areas where accumulations appear to be greater, re-evaluate your route.
