Avalanche danger will increase later today as a serious storm brings more snow, rising temps and lots of wind. Choose terrain carefully and minimize your exposure to the run-outs of avalanche paths when the storm hits.
Summary
Weather Forecast
A big system arrives today. Up to 10cm today, and another 20cm are expected overnight. Alpine temps are expected to rise to -2 but freezing levels will hopefully stay below ~1500m. Moderate SW winds, with strong gusts, will load lees. On Sat snow rates will taper off but moderate to strong W'ly winds will continue to load lees. Sun will be similar.
Snowpack Summary
Up to 40cm of light snow overlies settled snow from last weeks storm. In most areas the snow is loose and sluffs easily. Tests indicate that as it settles into a slab it may be triggerable. In some alpine areas wind slabs exist on lee features from S-SW winds. Jan 4th interface down 60-100cm and remains a concern in less traveled areas.
Avalanche Summary
Yesterday numerous size 2's and 1 size 3 occurred on steep N aspects, triggered by windloading, and ran into the fans. On Tues, size 2.5 avalanches occurred from S aspects at ~2300m. Wide crisp crowns up ~1m deep indicate that they likely failed on the Jan 4th. In addition, skiers could easily trigger the loose surface snow, sluffing fast.
Confidence
Timing, track, or intensity of incoming weather system is uncertain
