More detailed information about the snowpack: 

Quick road tour post storm. Noted a crown line along one of the ridges near Punta Bardini, possible D2. Moderate winds noted along 395 in favored areas with snow banners on many of the visible peaks. Strongest winds closet to the Crest. Some impressive snow transport. Debris noted on Mt. Wood's East Face x 2, possible D2's. Mt. Wood Windloading - Picture attached

Earthquake Dome - 30 to 40 cm ( 12-16") new snow. Fist -, over 4F+ Decomposing. In sheltered locations further from the Crest the new snow has little to no slab character. Hand shears negative. No apparent weakness in the new snow or at the old/new snow interface. Test slopes negative. Low angle ENE aspects below 8400' light melt/freeze crust forming at the surface where the sun filters through the trees. Ridgetop, evidence of some wind stripping, westerly aspects at 9300' mixture of softening melt/freeze crust and new soft snow in shaded pockets.
