Wind slabs are likely to be encountered at upper elevations and may be reactive to human triggering, especially in lee features.
Weather Forecast
SUNDAY NIGHT - Cloudy with isolated flurries / southwest winds, 10-25 km/h / alpine low temperature near -6MONDAY - A mix of sun and cloud / southeast winds, 10-20 km/h / alpine high temperature near -3 / freezing level 1700 mTUESDAY - A mix of sun and cloud with isolated flurries / northwest winds, 10-25 km/h / alpine high temperature near -2 / freezing level 1800 mWEDNESDAY - Mainly cloudy with scattered flurries, 5 cm / south winds, 10-20 km/h / alpine high temperature near -3 / freezing level 1800 m
Avalanche Summary
On Saturday, there was a report of a human triggered size 1.5 wind slab avalanche on a northeast aspect at 2600 m.On Thursday, there were reports of a few human triggered size 1 loose wet avalanches at treeline within the new snow.
Snowpack Summary
15-25 cm of recent storm snow in the alpine and at treeline sits on a melt-freeze crust on all aspects except for north slopes above 1800 m, where it sits on dry snow. Snow is disappearing rapidly at lower elevations.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
