Sorry I'm getting this out so late, but big day here.   I only ran into a couple of you out in the backcountry today, so I'm assuming most spent their time inbounds at the resort.  Lot's of avalanches everywhere inbounds with cutbanks, lower front steeps and pretty much everywhere.  I'll get into more specifics in tomorrows forecast but avalanches were occuring everywhere with ski cuts, explosives as well as numerous naturals.  

I did make it up above Williams Lake but visibility was horrible and easily blowing in the 40 to 50 mph range.  Collapsing and shooting cracks everywhere with propagation going 500' or more.  There were several naturals and I apoligize that the photos probably aren't better, with visibility being so bad.  Take home points from today is that canyon winds were raging with a max gust of 56 mph on Highline Ridge out of the West.  Around 8" of snow has fallen since 5AM this morning (measuring snow in these blustery conditions is almost an impossible task)  with around .8" of water so far.  I did get to see some debris piles off of Backside of Kachina Peak but had no way of telling where they started or how big the crown was.  Stability tests were showing that soft wind slab was bonding well with the old snow and showing a willingness to propagate. Temperatures remained warm with temps hovering around freezing at 9200' all day.

All our weather stations are down currently but around 8" of new snow with .8" of water during the day.  Measuring snow and precip amounts is a tall order anyway with strong winds.  Lots of blowing snow with our traditional up canyon winds.
