Melissa and MIiles found about 110cm of new snow since the rain 3 weeks ago. So far, it has all landed right side up and settling. Snowfall yesterday was already beginning to get denser as they were headed out.  Concerns are windslabs in the N-NE-E aspects near and above treeline and the recent storm slabs.

We've received about 1 foot of snow on the level since last week and steady westerly winds have piled it up even deeper on lee aspects.  Warming temperatures with the most recent accumulation of several inches last night will have created an unstable situation at the surface, particularly in those wind-loaded areas.  Touching off a small slab in steep terrain could step down to lower layers.

MODERATE avalanche danger today for mid and upper elevations for the entire forecast region with isolated areas of considerable in steep exposed terrain near ridgetops on windloaded aspects N, NE, E.  With increase in wind, snow and temperatures watch for heavier snow on lighter snow in the upcoming storms producing 1.5 feet of new storm snow weak layers.

In the Bitteroots near Lookout Pass we have 3 feet recent storm snow which has a decent bond to the 8 inch icecrust from 3 weeks ago with some instability within the top 3 feet of storm snow due minor snow density changes between these storms.  Things are starting to consolidate.  The upper few inches of snow have some wind affect in most areas with more on steep exposed upper elevations.
