Red Flags Comments
It is spooky out there, MANY recent avalanches. While sitting here I can count 16 avalanches I could see today. From what I could tell the all occurred during or recently after the storm.
Avalanche Problem #1
Problem
Persistent Weak Layer
Trend
Same
Problem #1 Comments
This PWL is no joke. Very well preserved facets about 50cm off the ground have the ability to connect terrain in an impressive way. This combined with a heavy PNW style slab on top has lead to widespread avalanches and continued instability.
Avalanche Problem #2
Problem
Wind Drifted Snow
Trend
Increasing Danger
Problem #2 Comments
We saw evidence of old wind slabs that had released below cornices. We also watched these being filled in though out the day.

Comments
As expected we pulled and ECTP14 at 52cm up from the ground on 2-3mm well preserved facets below a 1f cohesive slab.
Below I will include a number of avalanche photos from the recent avalanches we have seen. Many are at mid and upper elevation on N-E-SE facing slopes. But there are a couple that are at low elevations near roads. To see more there is an observation from the 28th with a deeper dive into a larger avalanche.
1: Low elevation N avalanche
2: SE avalanches around 9700'
3: Low elevation road cut
4: Avalanche connecting through road cut, E 10,000'
5: NE avalanche 9600'
There are other avalanches to see out there.
