Avalanche Advisory
Advisory: Abajo Area Mountains Issued by Eric Trenbeath for Saturday - March 19, 2016 - 7:12am
bottom line

Overall, the avalanche danger is generally LOW but unstable snow may exist on isolated terrain features, particularly in upper elevation, steep and radical terrain.
special announcement

The Abajo / Blue Mountain advisory provides detailed snow, mountain weather, and avalanche information on weekends. During the week, an overall danger rating will be provided with current condition information available through the weather links below.

Please help guide our discussions of website maintenance, upgrades or possible changes in coming years. Take this brief survey. As a way of saying thanks we'll be raffling a free avalanche class and other free stuff like hats, beanies, water bottles, etc
current conditions


It's spring in the Abajos and the snowline is creeping higher. Many south facing slopes are melted out entirely. Buckboard Flat still has a base depth of 30" and sheltered, north facing aspects have about 4' of coverage but between the wind, sun, and unusually dry February, and as of yet March, things are going fast. Most snow surfaces have some degree of melt freeze crust going on, and only the highest, northerly aspects hold any dry snow.

It's just above freezing at Buckboard Flat this morning, and temperatures are in the mid 20's on Abajo Peak. Winds are moderate and westerly.

description

The avalanche danger is mostly low at this time. But low danger doesn't mean no danger and areas of unstable snow may still exist on isolated terrain features. Here are problems to remain aware of:

Wind Slabs: Isolated wind slabs may still exist on the lee sides of ridge crests and terrain features in upper elevation, wind exposed terrain, primarily on slopes with a N-NE-E aspect.

Persistent Slabs: It may still be possible to trigger a slab on weak sugary, faceted snow in areas of steep, rocky, and more extreme northerly facing terrain. Slide paths that are repeat runners are also suspect.

Loose wet avalanches: Daytime heating can make the snow wet and sloppy and prone to avalanching. Look for signs off instability such as rollerballs, pinwheels, or wet sluffs sliding down the slope. Stay off of and out from under steep slopes when these signs are present.
