Avalanche Forecast
Regions: Sea To Sky.
Confidence
Fair - Due to variable snowpack conditions
Weather Forecast
Saturday-Monday: Mainly sunny with clear skies and light winds. Alpine temperatures near -5, dropping overnight.
Avalanche Summary
Natural cornice fall triggered size 1-2.5 slabs within recent storm snow on Thursday. Skiers also triggered wind loaded slopes to size 2. Intense wind-loading triggered several wind slabs, mainly on north aspects at alpine and treeline elevations, on Wednesday. Skiers also triggered size 1-2 storm/wind slabs.
Snowpack Summary
Recent snowfall was redistributed by very strong SE to SW winds, leaving wind slabs 30 cm to 1 m deep on many lee terrain features. Subsequent NW winds may have caused some reverse loading - so keep an eye out for wind slabs on all aspects. The upper snowpack structure is highly variable. On sunny aspects (and all aspects at low elevations), a sun/melt-freeze crust is now buried about 30 cm deep, while on high elevation shady aspects, 50-100 cm snow overlies an older melt-freeze crust. Mid and lower snowpack layers are well bonded.
