Watch for wind slabs around ridgelines as you gain elevation.
Gradual accumulations of snow this week may create small but reactive wind slabs.

Avalanche Summary
On Tuesday a size 1 rider triggered wind slab was reported.
Avalanche activity has tapered off but reactivity remains possible on isolated features or where new wind loading is occurring.
Snowpack Summary
Around 20 cm of recent snowfall continues to be redistributed by southerly winds into wind slabs on north facing terrain features. This sits over wind affected surfaces or a crust on south facing slopes that extends into the alpine.
The middle of the snowpack is strong and contains numerous hard crusts. Near the ground, weak faceted crystals exist. There hasn't been avalanche activity on this layer recently, but it remains on our radar as it may become active with abrupt changes to the snowpack, such as rapid loading (heavy snowfall or rain) or prolonged warming.
