Avalanche Summary
Loose wet avalanches were reported on Sunday from steep sun-affected slopes. Small loose dry avalanches were also reported on shady high-elevation aspects. See photo below.
With a cooling trend in the forecast, we expect avalanche activity will be unlikely on Thursday. However, as storm snow accumulates Thursday night and Friday, avalanche danger will rise accordingly.
If you are headed into the backcountry please consider submitting a MIN report.
Snowpack Summary
Previous strong sunshine and warm temperatures formed a crust on most surfaces, except on north-facing alpine slopes, where the old snow remains soft. Facets and surface hoar have been reported developing in shady, sheltered areas. The mid and lower snowpack is dense, well-settled, and currently free of concerning layers.

Terrain and Travel Advice

- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
- Periods of low danger may be a good time to increase your exposure.
