It didn't take much, or long, for a Wind Slab avalanche hazard to develop today above the Going-to-the-Sun road.
Felt like winter.
Triggered 4 thin soft slabs of drifted snow between 6850' and 5900', plus got several other lower-angled slopes to crack. Limited to areas where the wind had deposited a slightly denser layer. Slabs 1-6" thick, F+ to 4F- hard, failing on low density precip particles deposited at the start of the storm - or on small facets (melt-layer recrystallization) that were forming as cold snow covered moist-wet old snow surface. Propagated surprisingly wide - sometimes entire patch of snow cracked. These had very little volume and did not run far.
