Kernpunkte

Lingering wind slabs may still be reactive to human triggers on leeward slopes below ridgetops.

    Lingering wind slabs may still be reactive to human triggers in wind affected terrain at treeline and above.

  • Loose Wet

    Recent storm snow below treeline may quickly become moist and increase the likelihood of loose wet avalanches.

Confidence

Low - Due to the number of field observations

Snowpack Summary

Lingering wind slabs may still be reactive to human triggers on leeward slopes below ridgetops.In the south of the region, two layers of surface hoar are buried early-March and mid-March are approximately 70-100 cm deep and most prominent on north to east aspects. Further north, these layers are around 40 cm deep.Below these March layers the mid-pack is generally well-settled and strong. However in the far north of the region there are weak sugary facets near the bottom of the snowpack.
