Avalanche Forecast

Moderate - Intensity of incoming weather systems is uncertain

A change in the weather pattern is upon us as the upper jet shifts to a westerly flow allowing a series of Pacific frontal systems to track across the Coastal Regions.Tuesday: Snow 10-25 cm with heavier amounts being more coastal. Alpine temperatures near -6 and ridgetop winds moderate-strong from the SW. Wednesday: Cloudy with snow amounts 5-15 cm. Alpine temperatures near -8 and ridgetop winds moderate with strong gusts from the SW.Thursday: Snow amounts  5-15 cm. Alpine temperatures high of -3 accompanied by gusty (90 km/hr) ridgetop winds. Freezing levels rising to 700 m.

On Sunday no new natural avalanche activity was reported, however; several skier triggered wind slabs up to size 1.5 were triggered in alpine elevations.  Changing wind directions and new storm snow will likely develop new wind slabs in the alpine.

A recent addition of up to 10 cm of new snow has not dramatically changed the snowpack structure, but Saturday night's storm buried a new layer of surface hoar which will get buried deeper after tomorrows snowfall. At this time it is unknown how well preserved this surface hoar. A variety of surface conditions exist including isolated wind slabs, pockets of soft snow (15 to 25 cm deep), sun crusts, and surface hoar. A supportive rain crust exists below 1000 m. A layer of surface hoar that was buried on February 10th can be found buried 30 to 60 cm deep at tree line elevations and has been reactive in some recent snowpack tests. Below this layer, the snowpack is generally settled and strong. The exception is shallow snowpack areas around Bear Pass and Ningunsaw where basal facets remain an ongoing concern.
