    Avalanche activity will remain unlikely today throughout the forecast region.  Recent strong winds have left scoured surfaces, hard slabs, and small wind slabs in near and above treeline areas.  Wind slabs have gained strength over the last week with few signs of instability and limited snow available for additional wind transport. 

    A rain event on Jan. 1 has left a rain crust up to around 9000'.  This rain crust and other wind scoured areas could exist that pose travel concerns with sliding falls possible in steep terrain. 

    Sunny skies are forecasted today with increasing temperatures and decreasing winds.  Snow surface warming is expected on southerly aspects.  Small loose wet avalanche activity in the form of roller balls and pinwheels are possible today.  These are expected to remain small in size and located on southerly aspects, in low to mid elevation areas, and in terrain around rocks, gullies, and trees.   

    Normal caution is advised when traveling in the backcountry.  Have a travel plan, travel one at a time through avalanche terrain, and communicate effectively within your group.

Avalanche Discussion

Observations came in from Castle Peak and Mt. Judah (Donner Summit area) and Slide Mountain (Mt. Rose area) yesterday.  Variable snow surface conditions existed at all locations with an assortment of wind scoured surfaces and crusts.  Southerly aspects had limited warming into the midday, with cold temperatures and increasing clouds in the afternoon.

A small amount of graupel that fell on Saturday night was found in the Donner Summit area.  Surface hoar was found at all locations.
