Earlier in the day dug a pit and got ECTP17(SC) down 55cm on the February 19 layer of surface hoar and facets. Also observed previous avalanches size 1.5-2.5, released during yesterday's storm. Also felt several whumpf's. Most of day stuck to slopes under 30 degrees. Skied this one steep slope carefully and remote-triggered this avalanche.
