Even with limited recent snowfall, storm slabs may be reactive in sheltered areas where they overlay weak surface hoar crystals.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Be aware of the potential for larger than expected storm slabs due to the presence of buried surface hoar.

Recent snow may have accumulated atop weak surface hoar crystals in wind-sheltered areas and a widespread crust.

Avalanche Summary

No new avalanches have been reported in this region.

If you do go into the backcountry, please consider submitting a MIN report.

Snowpack Summary

Roughly 10 to 20 cm of recent snow has buried large surface hoar crystals in wind-sheltered terrain features at treeline and above.

A widespread crust is now buried by approximately 20 to 40 cm of snow at higher elevations.

Conditions below treeline remain rugged with a shallow snowpack and a mix of hard refrozen surfaces or moist snow.
