Primary Problem: Wet Snow
Bottom Line: By mid-morning, on sunny slopes, any surface crusts that formed overnight will be breaking down and wet avalanche danger will be rising. Mostly we’re expecting relatively small wet loose slides, but the whole array of wet snow avalanche concerns are possible today, including wet loose slides entraining the whole season’s snowpack, wet slabs, or cornice collapses. Plan to get off sunny slopes early. Triggering avalanches in dry snow is becoming less likely, but is still possible, particularly on wind-loaded, high elevation, shady slopes.

Driving home from Bridger Bowl I spotted a number of wet loose avalanches in Argentina bowl. It was 1:30 PM when I saw them and the sun was still blazing. I would expect there was more activity as the afternoon progressed.

From IG message: “Rode the banana today.. lots of fast moving sluff. Had a mid elevation pocket pop. New snow seemed to have bonded well, the spot that did pop had formed into 12” slab below rock face. Little to no signs of instability.”

From obs : "After skiing two laps on East facing terrain two basins north of Anger Lake basin and seeing no significant signs of instability, we descended into a north facing gully around 8,200ft and triggered an avalanche on the new snow/old crust interface. The crown was 4-18 inches deep and propagated the entire width of the gully ~40 feet and ran the entire length of the gully ~500 vertical feet. I was able to ski out of the avalanche right as it broke and was not carried. "

  • From IG: Very touchy on Hollywood wall this morning. All slopes easily propagated 4-6” deep on a firm bed surface. Most were less than 50’ wide with the exception of the slide in the couloir which propagated down the entire couloir, maybe 500’ wide, and ran through the exits into the main bowl.

  • We dug below the first cliff band and found 7' of snow, the bottom 2' consisting of weak facets. A Deep Tap Test showed a clean shear at this interface. An avalanche could be triggered by 3 ways: more load from snowfall or wet avalanche debris, melt-water percolating through the snowpack to the facets, or human triggering from a thin spot.
