Weather Summary

Weird weather day in the Lost. The morning started with what felt like a clearing trend and windy conditions. Winds calmed and clouds stacked against the mountains from the north. The air in the clouds was very warm and wet and was condensing on exposed objects (clothes, rocks, the snow, etc.) and trapping significant heat and reflected radiation. Felt like hanging out in a mountain steam room. Clouds hung around until around 1700, when skies began to quickly clear.

Snowpack Observations

Recent precipitaion fell as mostly rain below 7500'. Above 9,000' roughly 15cm of new snow had accumulated. The new snow appeared to arrive in three pulses: a dense, wet pulse, then an energetic graupel pulse, followed by colder snow falling. These three pulses each made up about one third of the new snow. I experienced cracking and collapsing in thin, freshly deposited wind slabs. These appeared to be failing on the layer of mid-storm graupel. I avoided some steep, high-consequence, upper elevation terrain that harbored recently formed wind slabs.

Terrain Use

Avoided some steep, high-consequence terrain that held recently formed wind slabs.
