More detailed information about the snowpack: 

SW and W winds picked up during the morning on Lake Fork and scoured ridgelines. Snow remained available for transport as of noon.  Winds were non existant below Williams Lake.  Wind slabs were just starting to form and I expect tomorrow we will see wind slabs on leeward slopes below the ridgelines.  Stablilty tests did reveal a graupel layer from Nov 27th that was just above a pencil hard wind slab producing a clean shear with an ECT.  Typical faceted snow was found in the bottom 30 cm of the snowpack.
