Cornice falls may trigger large avalanches on slopes below.

Avoid traveling on slopes below cornices and give them a wide berth while traveling on ridetops.

No new avalanches were reported on Sunday. Check out this MIN report showing a couple of old large slabs failing on a crust on northerly aspects at treeline.

NOTE: Observations are currently very limited in this region. Make observations and continually assess conditions as you travel.

High freezing levels have formed a surface crust everywhere except possibly the highest north facing terrain.

The snowpack is generally well-settled and strong, although dormant weak layers may still exist in some areas.

Sustained high freezing levels with poor overnight recovery have the potential to awaken dormant weak layers.

Lower elevations are melting out rapidly.

• Cornice failures could trigger large and destructive avalanches.
• Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
• Back off slopes as the surface becomes moist or wet with rising temperatures.
