Highlights
With a slow clearance tomorrow, storm slab is the main concern after all the new snow, but if the sun starts to shine, greenhousing could increase the loose wet hazard quickly. Think about the terrain above you and avoid runout zones.
Conservative route choices are a good idea tomorrow to allow the new snow time to settle.
