Avalanche Summary
Recent reports include wet loose avalanches up to size 2.5 in response to warming and sunshine. Large glide avalanches were also reported. On Saturday, a size 3 glide release removed trees and left a 4-5 m deep deposit near Shames. Last week, a large icefall triggered a slab in the Bear Pass area, creating a size 4 avalanche.
Snowpack Summary
Cornices and icefall are an increased concern now that spring is upon us. A melt-freeze crust exists on solar aspects and at low elevations. In some areas, limited overnight cooling has kept surface snow from re-freezing, leaving it loose and cohesionless. Forecast rainfall at low elevations may keep the snow surface weak. Pockets of dry snow and surface hoar may still be found on high north aspects. Areas of wind slab formed with recent easterly outflow winds. Glide cracks have opened up and pose the threat of full-depth releases, especially on steep rocky terrain features.
Problems
Wet Slabs
Warm temperatures or rain may continue to weaken surface snow, especially below treeline. Wet slides can push you around, entrain mass and become surprisingly large. Also, avoid traveling on or underneath any slopes which sport glide cracks.
Aspects: All aspects.
Elevations: All elevations.
