In sintesi

The avalanche danger is MODERATE on steep, upper elevation slopes around the compass. Human triggered avalanches involving slabs of recently deposited, wind drifted snow are possible. The avalanche danger is generally LOW outside of wind affected terrain.

The current snowpack is very weak. Anticipate dangerous conditions to develop as a series of storms begin to impact our area.

The snowpack is still very shallow and rocks, logs, and stumps remain a hazard right now.

    Shallow soft slabs of wind drifted snow have developed as a result of yesterday's winds and meager snowfall amounts. Look for fresh slabs of wind drifted snow on the leeward sides of ridge crests and terrain features such as gully walls and subridges. You should be able to recognize them by their smooth, rounded appearance, and cracking is a sign of instability.

    As new and wind drifted snow accumulates through the next series of storm systems, expect slabs to become deeper and more widespread. As the load increases, slabs will invariably begin to stress the underlying, weak snowpack, and deeper avalanches involving persistent weak layers will become increasingly more likely.

Weather

We're in the grip of cold, northwest flow following the passage of yesterday's storm and mountain temps are in the single digits. We should see some clearing and a few sunny skies this morning. By this afternoon a weak shortwave moves through bringing a chance for a couple more inches of snow. NW winds will blow in the 10-15 mph range along ridge tops and high temps will be near 20F. A chance for showers remains overnight, with a break in the action on Saturday. By Sunday, a good looking storm tracking through the Four Corners region should be upon us.

General Conditions

Yesterday's northerly winds blew longer and stronger than I anticipated and they managed to whip an angry inch of new snow into fresh drifts 4"-6" deep. I expect this drifting to be spotty and not well connected, but there could be some surprises out there with slabs breaking farther and wider than expected. It's a complex landscape out there. The overall snowpack remains quite thin and of generally poor structure. Solar aspects are shallow, crusted, or bare. Northerly facing terrain is either weak and faceted through to the ground, or wind damaged. As new snow begins to pile up, we can expect avalanches to fail first at the old weak, snow surface. As a greater load accumulates, avalanches failing deeper into the snowpack will become increasingly more likely. See Dave's video below describing the current structure.
