As of October 25th, snow depths around the forecast area range from 10" to 18" at 6,000'  (3.5" to 4.5" of Snow Water Equivalent).  In most terrain, this has accumulated harmlessly over bare ground and/or consolidated into a thick crust that formed during the past week's warm weather.  However, on the highest, coldest slopes, wintry snow may persist, and below it, faceted snow layers that formed earlier in the month (See this observation and this observation).  We have limited field observations right now, but it is worth monitoring for persistent slab issues if you are traveling anywhere with a layered snowpack.  These instabilities are slow to heal, and could produce avalanches that involve the entire snow depth, up to a couple feet deep.  Its easy enough to dig down to the ground right now: look for sugary, faceted snow layers below last weekend's snow.   Snow that is well anchored by protruding brush, logs, or talus is genenerally not a concern - terrain that has been smoothed over by windblown or snow accumulations should be treated with suspicion until proven innocent.    

The most recent surface crust that formed this week will act as a slick bed surface with the arrival of fresh wind slabs that form this weekend.  A series of fronts this weekend will bring modest snow accumulations and strong winds that shift from the Northwest to the East.  Watch for new windblown snow to form small but easily triggered slabs in leeward terrain that has existing smooth snow coverage.  These slabs will gradually heal into the early work week as time passes and winds are forecasted to subside.  We may see another pulse of snow and strong winds again early next week to refresh the problem.    Remember that any avalanche, large or small, can have harsh consequences if it drags you over rocks, over cliffs, or into trees or stumps. 

The FAC will monitor conditions through the fall and post updates as conditions warrant. We anticipate daily forecasts and full operations to begin in December.  

 Now is the time to get your gear dialed and brush up on your avalanche knowledge.   The 2019 Northern Rockies Snow and Avalanche Workshop has a great lineup of presentations, vendor booths, raffles, and an all-around good time.  The event is November 16th, 2019...all the details are here.   Registration is open! Stay tuned for our upcoming avalanche class schedule later this fall.
