Let's keep our fingers crossed that the Grinch (ice pellets and rain) will not spoil the long-awaited snowstorm.

Altogether, avalanche danger will increase on Saturday.

If you venture into the backcountry, please consider sharing your observations.

Avalanche Summary

No new avalanche activity has been observed or reported. Please continue to share your observations at [email protected], or with the Mountain Information Network.

Snowpack Summary

In general, 10 to 20 cm of low-density snow is found in wind-sheltered areas. On leeward slopes, this new snow overlies a hard surface or wind-affected snow. The thick December 8 crust is buried down 20-50 cm. This crust supports a skier's weight... and even more! The average snowpack height is still very thin, averaging around 50 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

  • Closely monitor how the new snow is bonding to the old surface.
  • Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.

Avalanche Problems

Storm Slabs

Touchy storm slabs will develop with forecasted snow amounts. Human triggering is likely on leeward slopes and cross-loaded features. Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
