Avalanche Summary
No new avalanches have been reported. Small wind slab avalanches may form in response to light snowfall and strong winds on Thursday.
Snowpack Summary
On high north-facing terrain. light amounts of cold, lower density snow overlie a widespread thick hard crust. Below about 2000m there is no snow on the crust and surface runnels show the effect of last week's rain showers. Sun-exposed slopes became moist, or wet with recent daytime warming and solar radiation and are also likely refrozen. Below the surface crust, the snow may still be moist; however, the mid and lower snowpack are generally strong and well-consolidated. Most of the terrain below treeline is below threshold for avalanche activity.
