More detailed information about the snowpack: 

Wind sheltered areas are still holding good creamy snow (6 to 9 inches).  Strong West winds today were easily transporting the new snow (6 to 11 inches) above treeline into stiffening wind slabs.  Reports earlier in the morning from inbounds control teams were propagating wind slab avalanches on the leeward side of ridgelines.  With poor visibility and strong winds we did not make it to ridgelines above treeline today but could see winds easily transporting snow above treeline and in open wind effected areas. 

We received .8 to 1.1 inches of water with the storm but did not observe any natural avalanches that had stepped down into older layers.

More detailed information about the weather: 

Mostly cloudy day with very light snow flurries at times.  The bigger story today was the strong West winds that were transporting snow at ridgetops.  Winds picked up in the afternoon but were moderate to strong all day above treeline and were easily transporting snow.
