Avalanche Forecast
Issued: Jan 21st, 2014 4:00PM
The alpine rating is Deep Persistent Slabs and Wind Slabs.
, the treeline rating is , and the below treeline rating is Known problems includeThe potential remains to trigger deep slabs on steeper terrain especially in thinner snowpack areas. Lots of good riding can be found on moderate angled terrain. JBW
Summary
Weather Forecast
The upper warm ridge will continue to deflect any major precipitation and keep temperatures moderate at least through the weekend. This will give a slowly stabilizing trend to the snowpack.
Snowpack Summary
Surface hoar growing. Midpack pencil with no significant shears. Sudden collapse at base in old DH and on top of Crust in the very hard range. Potential for human triggering in thin areas.
Avalanche Summary
No new avalanches observed.
Confidence
Problems
Deep Persistent Slabs
Thin areas and steep terrain that has notĀ yet avalanched should be avoided. Thicker moderate angled terrainĀ with low consequences would be a good choice.
- Watch for whumpfing, hollow sounds, and shooting cracks.
- Be aware of the potential for full depth avalanches due to deeply buried weak layers.
Aspects: All aspects.
Elevations: All elevations.

Wind Slabs
These slabs are fairly isolated now, but could cause a deep step down avalanche if triggered.
- Use ridges or ribs to avoid pockets of wind loaded snow.
- Travel on ridgetops to avoid wind slabs on slopes below.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.
