Avalanches may be unlikely and isolated right now, but they are also hard to predict and could be consequential, especially in extreme terrain. Determine the risk vs. reward of traveling in avalanche terrain. There is widespread poor snowpack structure in our zone. Strong slabs of snow rest above weaker layers. Snowpit tests show that the persistent weak layers have mostly adjusted to the load above, but if you hit just the right spot you could still trigger an avalanche. You may not see any signs of instability before this happens. The snowpack is still very thin and the recent sun and strong wind events have shaped snow surfaces in most areas into a variable mix of wind board, wind crusts, sastrugi, and sun crusts. Some protected slopes still hold recycled powder but they are also thin. Hitting buried objects is a significant hazard. Use normal caution and good backcountry practices to reduce your risks when travelling in the backcountry.
Recent observations continue to find large grained facets and depth hoar from November snowfall at the base of our snowpack. Variable slabs of snow rest on these weak layers. Snowpits show that the weak layers have mostly adjusted to the load, but still could produce propagation given the right trigger.
Recent sun and strong wind events have created variable snow surface conditions. Many areas are wind scoured to the ground, and others have a mix of wind board, wind crusts, sastrugi and sun crusts at the snow surface.
The January 6th storm brought 3 inches of new snow to the higher elevations. High wind speeds during the storm did not allow much, if any snow to settle. Adding little to the snowpack.
The snowpack remains very thin and we are all hoping for more snow.

An atmospheric river currently impacting the Pacific Northwest is bringing us increased temperatures, clouds, and winds today. As the storm passes by to our north, the winds and clouds will decrease into tomorrow. Warm temperatures and sunny skies are expected for Thursday.
