Forecast for the Abajos Area Mountains

Eric Trenbeath
Issued by Eric Trenbeath on
Friday morning, December 25, 2020
A MODERATE avalanche danger exists on steep slopes facing NW-N-SE where stiff wind drifts or shallow soft slabs are overlying layers of weak, sugary, faceted snow. Suspect slopes that have smooth, rounded deposits of wind drifted snow. or that feel hollow underneath. Cracking, whumphing, or collapsing of the snowpack are signs of instability. Even a small avalanche triggered under these conditions can have serious and painful consequences.
Low snow cover is the biggest hazard out there right now with rocks and logs lurking just below the surface, and even a small avalanche triggered under these conditions can have serious and painful consequences.

Weather and Snow
Two more days of dry, and sunny conditions are in store. High temps in the mountains today will be in the low 30's and SW winds will be light to non-existent. Things will start to change on Sunday as clouds move into the area - remnants of a weak system passing by to the north. By Monday, a closed low moving across the Great Basin will bring us our first chance for a decent shot of snow in a long time. It's currently looking like a "moderate" snow event. I'll keep you posted.
Snowpack Discussion
My partner and I went up to North Creek Pass on Saturday. Coverage is exceedingly thin and many sun-exposed slopes are dry. On shady aspects, depths range from 6"-18". The existing snow structure is very poor. In exposed areas, stiff slabs overly this weak, sugary snow, and we experienced frequent cracking and collapsing of the snowpack. These are clear red flag signs of instability. Places you could trigger an avalanche include steep drifted, gully walls, or shady slopes with continuous coverage, where more than about a foot of snow exists.
Snow totals at Buckboard Flat (8924')
Snow totals at Camp Jackson (8858')
Recent Avalanches
Dustin Randall from ROAM Industry sent in this photo of remotely triggered avalanche on a steep, northerly facing slope near 11,000'. This is exactly the type of setup we are concerned with right now. In spite of the low snow conditions, the existing, underlying snow is very weak, and anywhere that a slab exists on top, is primed and ready for an avalanche.
