A light amount of new snow has landed on heavily wind-affected surfaces in exposed terrain, the product of an intense wind event early last week. In sheltered areas, the flurries may have added to limited stashes of soft, potentially faceted snow. A crust will likely be found on steep solar aspects and at low elevations from warm temperatures and sun yesterday. A more widespread melt-freeze crust can be found 20 to 50 cm deep in most areas, and up to 80 cm in the snowiest parts of the region. This crust is near the surface below 1200 m.
Terrain and Travel
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
- Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
Cornices are large this time of year and were likely weakened by recent cold temperatures. Exposure to cornices should be minimized, especially during periods of warm temperatures or strong sun. Give them a wide berth when you are travelling on ridge lines and avoid overhead exposure to large cornices.
