In sintesi

There is a small chance that you will encounter an isolated pocket of wind-loaded snow on a high-elevation, exposed slope or some softening snow in terrain that sees direct sunshine. The bigger hazards to contend with are icey and cold conditions that will complicate rescue efforts should you fall and get hurt. Ensure you're carrying appropriate gear that you know how to use and take note of consequential terrain below you.

Avalanche Discussion

If you're doing your homework and reading the mountain weather forecast, you might notice that despite "uneventful" weather, some factors are a bit confusing. To help simplify, we don't expect any inputs to have much impact on avalanche danger. Just don't be surprised if you started the day with multiple puffys on and then are standing at ridgeline in a t-shirt. With that being said, here are a few more things to keep in mind if you get out:

  • If you were to find unstable wind-loaded snow, it would be in a piece of complex, rocky terrain at upper elevations. Investigate for instability if you see blowing snow. Use clues like rippled snow surfaces and cornices to identify the previous wind-loading pattern. Wind-loaded snow nearby will look comparatively smooth and rounded.
  • This observation from near the border of the Steven's Pass and East Central zones does a great job of highlighting the variable state of the snowpack right now. Agreeable skiing and riding can be found on north-facing, upper-elevation slopes. But as these observers were, be prepared with extra pieces of gear to get to it. The consequences of an uncontrolled fall on a steep slope could be substantial if you are carried into trees, rocks, or cliffs.
  • If the snow feels heavy and sticky on a steep slope in the sun, there is a higher likelihood of encountering a wet loose avalanche. Consider finding colder snow if you encounter these conditions.
  • Be sure to pay close attention to the forecast when stormy skies return. Presently weakening snow surfaces could be an issue when new snow arrives and falls on top.

Help NWAC Forecasters reduce uncertainty by submitting an observation. Obs are marvelously helpful even during periods of inactive weather and low avalanche hazard! Additionally, consider the current snow and weather circumstances as an excellent opportunity to refresh your avalanche rescue skills and check in on any gear that needs fixing!
