Isothermal snowpack and warm temps are wreaking havoc on the snowpack.  Cold temps will need to 
penetrate the snowpack for a day before stability begins to improve.  Avoid the bigger terrain 
features.

Danger Rating: 

Sunday - Alpine, Treeline, and Below Treeline
3 - Considerable Dangerous avalanche conditions. Careful snowpack evaluation, cautious route finding 
    and conservative decision making essential.

Problem: Wind Slabs

Any wind affected area in alpine terrain and gullied, and crossloaded features at treeline.

Travel and Terrain Advice: Resist venturing out into complex terrain, even if you observe no obvious 
signs of unstable snow. Dig down to find and test weak layers before committing to a line. Choose 
well supported terrain without convexities.

What Elevation Zone? - Alpine, Treeline
Which Slopes? - N through SE
Chance of Avalanches? - Possible to Likely
Expected Size? - Large

Problem: Deep Persistent Slabs

Avalanches in the upper snowpack are stepping down and waking up the deeper basal layers.

Travel and Terrain Advice: Avoid exposure to overhead avalanche terrain, large avalanches may reach 
the end of run out zones. Be wary of slopes that did not previously avalanche. Be aware of the 
potential for full depth avalanches due to deeply buried weak layers.

What Elevation Zone? - Alpine, Treeline
Which Slopes? - All
Chance of Avalanches? - Possible to Likely
Expected Size? - Large to Very Large

Problem: Cornices

Cornices have grown over the past week.  Many have collapsed and caused large avalanches on the 
underlying slopes.

Travel and Terrain Advice: Cornices become weak with daytime heating. Avoid steep slopes below 
cornices.

What Elevation Zone? - Alpine
Which Slopes? - N through SE
Chance of Avalanches? - Possible
Expected Size? - Small to Large
