What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Travel and Terrain Advice
- Use caution in lee areas. Recent wind loading have created wind slabs.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
Avalanche Problem 2: Persistent Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
40cm+ of snow is settling into a persistent slab which sits on the Dec 15 surface hoar. Expect the slab to possibly be reactive on steep unsupported and/or wind effected terrain. Solar aspects have a thin crust layer below the slab.
Travel and Terrain Advice
- Watch for signs of slab formation, such as whumpfing and shooting cracks.
- Avoid convexities and unsupported features.
Avalanche Summary
One size 1.5 ski cut surface slab off the west face of Cheops. This slide was observed on Dec 27th but suspect it happened in the Dec 24-25 time period. Expect lenses of thin windslab in the alpine and surface sluffing in steeper protected terrain.
Snowpack Summary
40cm+ of snow is slowly settling into a persistent slab which sits on the Dec 15 surface hoar. Currently the slab is stubborn to react or has yet to form. Windslab is prevalent in exposed areas above treeline. Solar aspects have a thin crust layer below the slab. Light snow overnight will have buried a thin layer of surface hoar, the Dec 27 layer.
Weather Forecast
Light snow with accumulations up to 8cm today. Alpine high of -13C with light East winds. Another 4cm snow forecast to fall overnight. Light Easterly winds and a trace of snow tomorrow. Temps will remail cold.
Flurries.Accumulation: 8 cm.Alpine temperature: High -13 °C. Ridge wind east: 10 km/h.Freezing level at valley bottom.
