Forecast for the Abajo Area Mountains

Eric Trenbeath
Issued by Eric Trenbeath for
Saturday, January 16, 2016

The avalanche danger is generally MODERATE but areas of elevated concern exist on steep slopes that face NW-N E where the new snow load from last week has added additional stress to buried weak layers in the snowpack. In theses areas, it is possible for the additional weight of a rider to cause a deep and dangerous avalanche. There is also a MODERATE danger for wind slab avalanches in upper elevation, wind exposed terrain. Avoid steep slopes that have recent deposits of wind drifted snow.

Special Announcements

The Abajo / Blue Mountain advisory provides detailed snow and avalanche information on weekends, with a general danger rating during the week.

Weather and Snow

Last week's storm really improved things and brought us close to having a real snowpack. We now have between 3-4' of snow on the ground. Wind and sun during the week has crusted over the snow surface in exposed locations, but soft snow still remains in sheltered areas.

WNW winds overnight have averaged 15-20 mph with gusts as high as 30. They are currently blowing in the low teens. It's currently 3 degrees on Abajo Peak and 19 at Buckboard Flat.

Avalanche Problem #1
Persistent Weak Layer
Type
Location
Likelihood
Size
Description

The underlying snowpack is very weak, consisting of sugary faceted snow. The storm snow from last week has settled into place on top but is now waiting for the additional weight of an unsuspecting rider to trigger a deep and dangerous avalanche. This danger exists on steep, northerly facing aspects right around treeline and above. This type of terrain, especially if is featured with gullies, steep roll overs and convexities, should be avoided for awhile.

Avalanche Problem #2
Wind Drifted Snow
Type
Location
Likelihood
Size
Description

Isolated, stiff wind slabs exist on the lee sides of upper elevation ridge crests and terrain features. A triggered wind slab has the potential to step down into buried weak layers creating a dangerous deep slab avalanche that could run to the ground. Avoid areas of wind deposited snow recognizable by their smooth, rounded appearance.
