Snowpack and Avalanche Conditions:
As we’re expected to see 4-6” today with stronger southwesterly winds, it’ll be a day of transition with the danger on the rise. The new snow will bond poorly on many of the upper elevation slopes of bullet-proof wind board and will likely sluff immediately and far on the steepest slopes. New sensitive wind drifts will also develop on the mid and upper elevation lee slopes and will initially be most pronounced on the north through east facing slopes. The snow may bond best to the warmer, rough snow landscape on the south-facing areas, but it may all be academic with heavy bursts of snow tonight and tomorrow with forecasted storm totals over two feet in many locations.
By the time it’s all said and done, we’ll likely have run the gamut of avalanche types, from loose and storm snow avalanches, sensitive wind drifts with the potential for remotely triggered slides where the snow comes in on the pockety faceted surface snow on the protected shady aspects. Lastly, it may be enough of a load to reactivate the basal depth hoar for step-down avalanches to run.
If you head out into the backcountry, you’ll need to exercise caution by moving through protected terrain and putting one person on a steep slope at a time. Offensive tactics like slope cuts and cornice drops should prove effective with the new snow instabilities.
A LOW avalanche danger this morning will rise to MODERATE today in upper elevation terrain that sees the most snow. Watch for immediate sluffing and developing wind drifts on the slick old bed surfaces on the steepest slopes.
We’re in for cold, stormy conditions through Wednesday with storm totals up an over two feet in favored locations. The pre-frontal winds will blow from the southwest today in the 25-30mph range with occasional gusts into the 60’s. Frontal passage will be in the early evening which should drop snow levels to the valley floor. Cold air aloft and lake enhanced snowfall should keep the hose on through Wednesday. Brief ridging moves in late in the week ahead of a couple of smaller disturbances over the weekend.
Our partners, the FUAC, will hold their next fundraiser at Brewvies on Dec 7th. There will be two showings of TGR’s new film, “The Anomaly”, at 7pm and 9pm. Advance tickets are available.
