Obvious Signs of Instability: Recent wet loose and slab avalanches, rain on snow, above freezing temperatures overnight

Weather: Rain, above freezing temperatures

Rain and warmth likely adding weight and consolidation to the slab component, tipping the balance and allowing natural trigger. Likely weak layer failure of October early season basal facets. Rain line approximately 3500-3700ยด.
