Highlights

MODERATE avalanche danger exists above treeline on steep slopes facing northwest through southeast. Human-triggered avalanches are POSSIBLE and today’s avalanches could fail into old snow and break deeper and wider than expected.

My mindset is avoidance of today’s avalanches. To find good riding, I’m shooting for slopes that do not have old snow at the ground by switching aspect and elevation, or by simply dialing back my slope angles to less than 30°.

    Old October and November snow has faceted on many aspects at, and above treeline on northwest-easterly aspects and is now buried beneath the new snow from the recent storm.

    Coming in warm and going out cold, 24 hour storm totals average 6” near the trailheads with the higher elevations receiving nearly a foot of medium-density snow with just about 1” of water weight. Remember… The recent storm snow piled up on the persistent weak layer which is buried 1-2’ beneath the snow surface. We have been missing the slab “ingredient” of an avalanche and the recent snow coupled with wind has created just that.

    I’m keeping my eyes peeled for shooting cracks and ears open for whoomphing or audible collapses… these are obvious signs of instability. Take advantage of our shallow snowpack and enjoy some easy digging. It does not take long to pull out the shovel and quickly identify strong over weak snow structure in a pit.

    Watch for slabs of wind-drifted snow that developed during the storm and are now covered by an additional 6”+ of new snow. I'm avoiding steep slopes in the windzone and features such as the leeward sides of ridges, chutes, and gullies that are specific to where today's avalanches live.

Recent Activity

On Monday, Joey and the ISA crew reported a small wind slab that was remotely triggered from a distance. This avalanche was 1’ deep and 40’ wide, failing on old snow. You can check out Joey's info here, and all other observations by clicking here.

Snow and Weather

Nowcast

Dissapating early this morning, the storm leaves 6" at our trailheads and closer to 12" at upper elevations. Temps are currently cool in the teens with light NW winds and moderate gusts into the 20s at upper-elevation ridgelines.

Forecast

Clearing will continue today and the sun should be shining by late morning. Temperatures will climb to near 30℉ at our trailhead, and closer to 20℉ at our upper-elevations. Light winds from the NW will continue with gusting into the 20 MPH range.

Futurecast

Not much to talk about looking down the road, I hope you enjoyed the action. A high-pressure ridge moves into town and park’s itself for the foreseeable future leaving us with sunny skies and mild temps for the next week.

Snowpack & Travel

Heading out today I am seeking protected terrain out of the wind zone where the PWL does not exist (mid-elevation, solar aspects). And of course, when things get confusing I just dial back my slope angles, removing a key component from the "ingredients" of an avalanche – slopes greater than 30°.
