Weather Forecast

Stable mild temperatures, freezing levels creeping up to treeline, pressure dropping towards the weekend, bringing moderate SW winds and light snowfall up to 10cm (over 72 hours).

Snowpack Summary

Isolated pockets of wind slab in alpine. Two distinct crusts are beginning to break down and are sitting in a relatively shallow and facetted snowpack. Field teams noticed widespread consistency in the surface form - yup, it's surface hoar.

Avalanche Summary

Isolated small loose snow avalanches occurred in steep alpine terrain with today's warming temps. Some larger sluffs triggered by skiers up to size 1. 

Confidence

Intensity of incoming weather systems is uncertain
