Recent Avalanche Activity & Snowpack Discussion:
Just about everybody and
their dog found sensitive soft slabs on steep slopes yesterday. Most were 12-16” deep and about 50-100’ wide,
with a few outliers up to 200’ wide.
They were most common in areas that saw the brunt of the early morning
southerly winds and/or the most snowfall.
In the lower elevations, warming temperatures and rain pulled some
debris out of some northerly facing chutes and gulleys. Of significant interest is a deep slab
avalanche that ripped out in upper
The danger will continue to rise today with the expected heavy snowfall today and tonight. Watch for cracking in the new snow on steep slopes of all aspects. Cornice drops, test slopes, slope and switchback cuts will all give excellent clues to instability. If you’re in steep terrain today in areas that have received the most snow, expect to trigger avalanches up to 1-2’ deep, potentially breaking deeper into older faceted snow. The faceted snow formed on a variety of aspects at the mid and upper elevations, but are most pronounced on west, north, and east facing slopes.
A CONSIDERABLE danger exists on all mid and upper elevation slopes steeper than 35 degrees. Human triggered avalanches in the storm snow will be probable on a wide array of aspects. Natural avalanches may also start to become more likely with continuing precipitation.
Those without good route finding and avalanche skills should stay on and below gentler terrain.
The slow moving storm will keep the engine going through tonight. 12-20” can be expected through tomorrow morning, but much depends on the slow track of the Low pressure system. Winds will remain light and variable until tonight when they’ll likely turn northwesterly. 8000’ temps will be in the mid-twenties with ridgetop highs in the mid to upper teens. We’ll get a quick break Monday with the next good-looking storm arriving Tuesday.
