Travel conditions are challenging and avalanche danger is increased if there is no recovery of the melt freeze crust.Start early and end early your adventure.

Avalanche Summary

No new avalanches observed

Snowpack Summary

The melt freeze crust on the surface was mostly non-supportive up to trreeline. Wind slabs in the high alpine on north aspects are still a concern for triggering. The melt/freeze crust is not expected to refreeze very well with Monday night's cloudy skies.Â Avalanche danger is directly related to daytime heating and re-freezing of the melt/freeze crust.

Problems

Deep Persistent Slabs

This layer becomes a concern when the melt/freeze crust breaks down with solar radiation or warming.

Be aware of thin areas that may propogate to deeper instabilites.Be aware of the potential for full depth avalanches due to deeply buried weak layers.Be aware of the potential for wide propagations due to the presence of hard windslabs.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

2 - 3

Loose Wet

Loose wet slides are a concern when with strong solar radiation.

Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

Aspects: East, South East, South, South West, West.

Elevations: All elevations.

Likelihood

Possible

Expected Size

1 - 3
