Highlights

Another round of snow Wednesday will gradually increase avalanche hazard throughout the day, especially near the cascade crest. Identify wind accumulated snow by observing fresh cornice development, actively blowing snow and stiff or textured surfaces. Steer around features and slopes greater than 35 degrees where you see these signs.

Avalanche Discussion

Small, but steady snow accumulations began to build fresh wind slabs over the last few days. Monday morning's snowfall allowed wind slabs to grow larger and deeper and Wednesday will bring additional snow that will continue to grow any lingering wind slabs. Wind slabs and sensitive fresh cornices will create heightened avalanche conditions on steep and poorly supported slopes at upper and middle elevations. A north component to the wind may result in wind slabs in unusual locations and add to the possibility of low elevation wind slabs. Use your powers of observation to identify the signs of recently wind-transported snow. Look for actively blowing snow, pillow-like drifts, fresh cornices, and stiff or textured snow as a sign that you could trigger a wind slab avalanche. Steer around steep start zones and slopes over 35 degrees where you see these signs.

Non-avalanche hazards:

  • Glide cracks have opened on steep, rocky slopes particularly at upper elevations. While cooler weather reduces the likelihood of a glide avalanche, continue to give these impressive features a wide margin for safety on the slopes above you.
  • Cornices near the Cascade Crest are large and many have yet to fail, but may lean precariously as the recent mild temperatures take its toll. Give them a wide berth as you travel along ridgelines and on the slopes below.

We continue to track the mid-January crust-facet combo throughout the Cascades, but it appears dormant and we don't believe it poses a threat at this time.

During the ongoing Covid-19 pandemic, continue to follow the latest guidance from local, state, and federal health officials. Avoid unnecessary risks that could impact first responders and stress medical resources.  Wear a mask when appropriate, practice social distancing, and consider recreating closer to home.
