Avalanche Summary

No recent avalanche activity has been reported.

Despite the low danger rating, the likelihood of triggering an avalanche will increase throughout the day with warming and strong solar radiation expected.

Snowpack Summary

Recent storm snow continues to settle and bond to an underlying crust. At lower elevations and south-facing slopes a surface crust will likely form overnight.

Surface snow will deteriorate and become moist throughout the day with daytime warming and strong solar effects.

Terrain and Travel Advice

  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
  • Be alert to conditions that change with aspect and elevation.
  • Be alert to conditions that change throughout the day.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
