Evaluate snowpack conditions before you commit to a slope.

Stay alert to conditions as they change with elevation and sun exposure.

Avalanche Summary

No new avalanches have been observed, but field observations have been minimal.

If you head into the backcountry please consider submitting your observations to the MIN.

Snowpack Summary

A thick melt-freeze crust is topping the snowpack in all areas except for shady, high-elevation north-facing slopes that may still have soft snow. This crust should melt and soften during daytime warming. The snowpack's upper 30 to 50 cm consists of various melt-freeze layers. The lower snowpack contains old weak layers that are no longer concerning.

Cornices are large this time of year and may become weak with daytime warming.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
