Hot day with morning and afternoon clouds although several hours midday was clear. Increasing pm clouds and a few lenticulars were indicators of the incoming weather. Light variable winds didn't cool snow surfaces where we traveled but cooled us slightly in the hot sun.
Large wet loose avalanches likely ran during 2/26-3/2 atmospheric river, most obvious on east and west aspects and many smaller ones on south faces. Saw very few isolated large wind slab (likely involving the late January persistent weak layer) on north to east aspects above 6000ft, probably occurring sometime during AR.
Valley bottoms up to 3500ft were rapidly melting and surfaces were frozen, but softening a couple inches midday. This continued as the trend on the southerly half of the compass to at least 5500ft. Snowpack was a surprising 4ft deep on a flat surface at 3100ft, reaching upwards of 5ft deep by 3500ft. We traveled to the interface of the southeast portion of the West Central zone, finding different conditions there as from more northerly parts of the zone.
