Avalanche Forecast

Low - Timing, track, or intensity of incoming weather system is uncertain on Wednesday

A weak upper trough Tuesday should deliver a small shot of precipitation and wind before a vigorous low makes landfall on Wednesday which has potential to bring significant precipitation. Unfortunately the weather models have not yet agreed on a solution with regard to track and intensity, but there will likely be less uncertainty as we get closer to Wednesday. Stay tuned for more details. TUESDAY: Broken cloud cover, freezing level beginning at valley bottom rising to around 500 m in the afternoon, moderate to strong west wind, 1 to 5 cm of snow.WEDNESDAY: Overcast, freezing level around 1000 m, potentially strong to extreme south/southwest wind, latest model run shows about 10 cm of snow. Stay tuned for more details. THURSDAY: Scattered cloud cover, freezing level around 1300 m, light to moderate southeast wind, 1 to 5 of snow possible.

On Sunday wind slabs up to size 2 were sensitive to skier triggering on northeast, north and northwest facing features between 1950 and 2100 m. Small wind slabs failed naturally and were human triggered Saturday to size 1 on south and southeast facing features between 1750 and 1900 m.

20 to 40 cm of new snow fell over the weekend accompanied by strong winds that were predominantly out of the south, southwest and west. This wind event formed widespread wind slabs that likely extend down into treeline. The new snow rests on the February 23 weak layer that consists of wind hardened snow, facets, a sun crust on solar aspects and surface hoar that is present at and below treeline. In the southern portion of the region a widespread crust is down 40 to 80 cm below the surface. Well-consolidated snow exists below the crust.Variable winds in the past month have created cornices on all aspects in the alpine. They will become touchier as they grow in size, as temperatures rise, and as the strong late-winter sun shines down upon them on clear days.
