Avalanche Advisory
Advisory: Abajo Area Mountains Issued by Eric Trenbeath for Monday - December 26, 2016 - 5:32am
bottom line

The avalanche danger remains CONSIDERABLE​ today in steep, upper elevation terrain where blustery winds and blowing snow have created fresh drifts and newly formed wind slabs. On slopes that face NW-N-E, a triggered wind slab also has the potential to step down causing a deeper and more dangerous persistent slab avalanche. The danger is MODERATE at mid elevations. For LOW danger stick to the lower elevations.

description

Moderate to strong, gusty winds with plenty of loose snow available for transport over the weekend translated to drifting snow and the formation of new wind slabs. Avoid areas of recently deposited, wind drifted snow and look for tell tale signs of instability such as cracking in the snow surface. A triggered wind slab also has the potential to step down into a deeper persistent slab.

description

The underlying snowpack is very weak, and additional snow load from overriding wind slabs has increased the danger for trigger a deeper persistent slab avalanche. You are most likely to find this problem on steep, upper elevation slopes that have a NW-N-E aspect.
