Avalanche danger
- Alpine
- Treeline
- Below treeline
Highlights
The avalanche danger is LOW and the snow is mostly stable.
Remember that risk is inherent in mountain travel and even a small avalanche could be consequential in complex terrain.
Recent Activity
None.
We do, however, continue to receive quality observations from the backcountry.
Snow and Weather
A storm! Actually two storms!
But they are well to the north and east...and well to the south and west of us. We will see much colder temperatures over the weekend and - if you squeeze your eyes tight - maybe a snowflake or two. Possibly a trace. We can only hope. But for today, we'll have mostly sunny skies, light to moderate winds from the west, and temps in the mid 30s down low, the upper 20s up high. Increasing clouds overnight hint of the two storms passing in the night.
Despite the lack of recent snow, you can still find soft recrystallized powder in the sun and wind protected mid-elevations.
There is a beautiful book, written by the French aviator Antoine de St. Exupery, called Wind, Sand, and Stars. Part of it details a time when his plane crashed in the Libyan desert. I think it was 1935. With little water between them, it wasn’t long until he and his navigator began experiencing visual and auditory hallucinations. Mirages appeared on the landscape, though they were always just out of reach. It’s a little like looking at the weather models these days…
Additional Info
Where Did the PWL Problem Go? Think of the snowpack like any other material under stress. Adding new snow or wind loading adds stress to the system. Over time, the snowpack slowly adjusts and avalanches become less likely, even though the facets don’t disappear entirely. You can then have poor structure, but stable snow.
This is a period of dormancy. The problem still exists, but is currently quiet. It’s been a week since the last reported slab avalanche, suggesting the snowpack is reaching equilibrium. That said, additional loading or warming could reactivate this layer.
During this stretch of high pressure, the snow surface is weakening and becoming faceted, especially in wind-protected terrain. Once buried, this surface snow will likely be the next layer we’re watching and could become the next persistent weak layer. It’s worth keeping an eye on how much the surface continues to weaken over the next week.
