Touchy storm slabs reactive to human triggers. Storm slab reactivity may persist for longer than usual due to the cold snow overlying a hard crust.
Weather Forecast
Monday: Mostly cloudy / Light, southwest winds / Freezing level sea level.Tuesday: Mostly cloudy / Light, southeast winds / Freezing level 250 m.Wednesday: 10-15 cm new snow/ Moderate to strong, southwest winds/ Freezing level 500 m.
Avalanche Summary
On Saturday, there were numerous reports of human triggered avalanches up to size 2.5 running on a knife hard crust much further than expected.
Snowpack Summary
45-80 cm of recent storm snow is sitting on a knife hard crust. These storm slabs have been very reactive to human triggers. The mid and lower snowpack are settled and well bonded with the average snowpack depth at treeline 250-300 cm.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
