In sintesi

Significant new snowfall in the past 24 hours will make for dangerous avalanche conditions.  Natural avalanches are possible and human-triggered avalanches are likely today on all aspects.  Stick to low-angle terrain features, and avoid traveling under steep terrain.

    It's a pretty simple story here.  It just snowed a lot in the Blues, and the snowpack needs time to adjust to the new load.  Travel advice is simple: cautious route-finding and conservative decision-making are essential today.  In the past 7 days, the High Ridge Snotel increased from 18-39" and gained 3.5" of Snow water equivalent (SWE) while the Milkshakes snotel went from 24"-51" and picked up 4.3" of SWE.  That's a significant new load, essentially doubling the snowpack in a short time period.  

Avalanche Discussion

The Blues are dominating the snow totals in NE OR, picking up 3-4+ feet of new snow this past week.  Mother nature needs time to adjust to the weight of this new load.  The highest elevation north-northeast facing terrain in the Blues very likely has weak faceted snow at the bottom of the snowpack.  The weight of the new snow from this week will test this weak sugary snow.  If you feel the snowpack collapse below you, it's likely due to the facets in the lower snowpack.  

The 5-Red Flags are a great tool to assist your decision-making. 

1. Significant new snow in a short time period

2. Cracking or collapsing of the snowpack

3. Sustained moderate winds

4. Rapid warmup

5. Natural avalanches
