Points saillants

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

    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.

    Rising freezing levels and rain at lower elevations may initiate loose wet avalanches.

Confidence

Low - Due to the number of field observations

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 is holding onto northerly aspects. Southerly winds have 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.
