Recent Observations:
With a full immersion into the storm yesterday at Castle Lake, observations quickly revealed touchy storm slab conditions. The upper elevations hosted slabs with depths ranging from 3 – 8 inches, with the potential to be much deeper. Shooting cracks and blocking snow were experienced on any steep convex terrain feature. West and southwest winds blowing snow at light to moderate speeds were observed. Wind effected snow was evident in the forms of wind pillows on open slope faces, textured surfaces near ridgelines, and large wind lips and cornices atop snow banks. Below-freezing temperatures paired with a harsh wind chill made for very real winter conditions.
Mountain Weather:
Over the last 24 hours mountain temperatures have sat in the upper teens with light to moderate winds blowing from the west and southwest. Overnight the mountains picked up a healthy seven inches of new snow with Ash Creek Butte reporting 14 inches. This morning will give way to the final flurries of snowfall as the storm departs the region. This departure will cause winds to shift to a northwest direction for a short period before shifting back to a westerly flow. A brief intermission between storms may allow for partial clearing of skies before the next storm wave crashes over the region this afternoon. Temperatures are expected to remain cool enough that snow showers will commence early evening in tow of the preceding storm. An atmospheric river event is stewing as another arctic low takes up position off the coast pulling in moisture originating from the tropics. Our region remains on the northern edge and will receive significant impacts over the next 72 hours.
