Forecast for the Abajos Area Mountains

Eric Trenbeath
Issued by Eric Trenbeath on
Saturday morning, January 8, 2022
An isolated or MODERATE avalanche danger exists on steep, mid and upper elevation north facing slopes where triggering an avalanche on a buried persistent weak layer remains possible. The danger increases with elevation and slopes with evidence of recent wind loading are more suspect.
Most low elevation and south facing terrain has generally LOW danger.
It's also still very low tide out there. Beware of rocks, stumps, and deadfall lurking beneath the surface.

Snow totals and temps at Buckboard Flat (8924')
Snow totals and temps at Camp Jackson (8858')
A storm system to the north has brought clouds into our area this morning. As the cold front tracks through to the SE we could see an inch or two of snow by afternoon. Otherwise, we'll see mostly cloudy skies, breezy, SW winds shifting to the NW, and daytime highs in the mid 20's. High pressure builds into the week.
Snowpack
Snow totals since last Friday are between 18" and 21" with locally higher amounts at upper elevations. Winds throughout the week have blown and drifted snow on to leeward aspects at mid and upper elevations. Northerly facing slopes above about 9500' have held snow since October, and this old snow has formed a weak, sugary, faceted layer at the base of the snowpack and this is where the trouble is. Recent and wind drifted snow has formed a dense slab over top of this weak, sugary snow and human triggered avalanches on steep, wind drifted slopes that face NW through E are possible. On slopes facing W and SE you may find unstable deposits of wind drifted snow. Wind drifts are recognizable by their smooth, rounded appearance and cracking is a sign of instability.

Description
A classic setup of strong snow over weak snow is developing on upper elevation, northerly aspects that retained snow from October. This October snow has become loose, weak, and sugary, or as we say, faceted. This faceted snow has formed a persistent weak layer at the base of the snowpack. Recent and wind drifted snow has formed a dense slab on top of this weak snow creating an unstable situation, and human triggered avalacnhes up to 2' deep are likely on steep, northerly facing slopes at mid and upper elevations.
Extended column test illustrates the weak layer where a slab avalanche is likely to fail.
