More detailed information about the snowpack: 

Went out to check out what the West winds on Thursday had done above treeline on East aspects.  Above treeline and areas exposed to wind, the winds have stiffened the low density snow.  Wind slabs were observed on East aspects below ridgetops and we did have a couple of natural wind slab avalanches.  Wind slabs seemed to be isolated to NE to SE aspects from the W / NW winds over the last two days.  

There were lots of small natural loose snow avalanches on steep slopes with our strong sun warming the snow surface. It's getting to be that time of year with our high sun angle and strong sun that after new snow and the first sunny day, the new snow heats up quickly.  Don't forget the glob-stopper and skin wax as the sun is heating up slopes quickly compared to the shady slopes that still have cold snow.

It seems like our persistent weak layers has not reached the tipping point with this recent round of snow.  But we continue to find faceted crusts and facets below wind slabs on NW through E and SE aspects that continue to be reactive in stability tests.
