BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

There's a LOW danger on most slopes in the backcountry. But hard wind slab avalanches are possible and pockets with a MODERATE danger do exist in exposed upper elevation terrain.


CURRENT CONDITIONS

Rain and freezing rain fell even at the highest elevations Wednesday and yesterday, turning the fresh snow into cream brulee.  Temperatures plummited overnight in the mountains, and the snow at mid elevations this morning will be more like concrete.  As opposed to powder we'll be looking for supportable snow in the backcountry today.  At least high elevation coverage is improving a bit. With one inch of new snow and another inch of mostly rain in the last 24 hours, there's now 16 inches on the ground containing just under 3 inches of SWE at the Tony Grove Snotel.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Very strong winds will continue today, and you might find some booby-trap wind slabs near upper elevation ridges and in terrain features like gullies and scoops...  The rain fell even up high cementing most of the snow in place, but watch for very hard, often hollow sounding slabs.  These can be quite tricky often allowing you to get well out on a slope before releasing.


MOUNTAIN WEATHER

Northerly winds will diminish this evening and a strong ridge of high pressure will move into the region for the weekend.  Looks like fair weather for the foreseeable future with no more storms on the horizon for a while.  Expect warming daytime temperatures in the mountains and stagnation in the valleys.
