Highlights

Wind slabs at higher elevations may be reactive to human triggers especially where a wintry snowpack exists.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–1.5

    South-southwesterly winds have produced isolated pockets of wind slab around ridges and in the immediate lee of slopes. Cornices may be touchy, give them plenty of space.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–1.5

    The likelihood of loose wet avalanches will depend on the extent of overnight crust recovery and the pace at which it warms up through the day.

Confidence

Low - Due to the number of field observations

Avalanche Summary

No new avalanches have been reported.

If you have any recent observations during your travels, we would greatly appreciate it. If you posted a photo or any other information to the Mountain Information Network (MIN), thanks!

Snowpack Summary

In the alpine, up to 10 cm cold wind-affected snow may still be holding onto northerly aspects. Southerly winds have likely produced isolated wind slabs around ridges and in the immediate lee features at upper elevations. Cornices have been failing recently.

Recent precipitation fell as rain upwards of 1800 m which has re-frozen as a crust well into the alpine on southerly aspects and all aspects below. Warm overnight temperatures will prevent crust recovery as you lose elevation. Expect thin surface crusts to break down quickly with daytime warming and rain.
