the area, leaving an unstable northwest flow behind it. Snow continued overnight, but I am sorry to
report that you may have more snow in your driveway than up in the mountains. While snow totals easily topped a foot in the
Wind will be the key to avalanche activity today. The light new snow did fall on a weak layer, especailly on the shady slopes, but in most areas the new snow has not formed much of a cohesive slab. However, along the highest ridges, the winds have been just strong enough to drift the snow into a slab that will be sensitive, especially in areas that received a foot or more of new snow. There are also reports of some wind drifts at the mid and lower elevations, too. Drifts on the shady slopes are sitting on weak faceted snow, so it may be possible to trigger slides from a distance in a few places. Out of the wind affected terrain, be prepared for loose sluffs on steep slopes
Also, hidden beneath the new snow are the old, hard wind drifts sitting on weak, sugary snow. There may be a few places where you could still trigger one of these stubborn, hard drifts, and they may break out above you.
The avalanche danger is CONSIDERABLE on slopes steeper than about 35 degrees with recent drifts of wind blown snow. This is just a small portion of the terrain, and drifts will be most widespread along the higher ridgelines, with only occasional drifts at the mid and low elevations. Other slopes steeper than about 35 degrees have a MODERATE danger, with human triggered sluffs and a few soft slabs possible.
A moist flow over the area will produce light snow in the mountains this morning, with another 3 to 5” possible. The winds will shift to the west by midday, and then southwest, and are forecast to decrease. Temperatures will remain very cold, warming into the single digits along the ridgelines, and to near 10 at 8,000’. A high pressure ridge will briefly move in over the area tonight and Friday before another cold, Pacific storm arrives for the weekend.
