It's time to start rising early to catch the coldest temperatures of the day. Finish your tour early in the afternoon, as danger ratings increase with the warmth of the day.
Weather Forecast
A mix of sun and cloud today, with convective flurries in the afternoon. Light ridge winds are expected, along with freezing levels rising to 1800m. The trend continues through the rest of the week: a mixture of sun and cloud; freezing levels in the valley in the morning, rising to ~2000m by the afternoon; and light ridge winds.
Snowpack Summary
Flurries delivered 10-15cm of snow to the alpine yesterday. SW winds redistributed this into thin soft slabs at alpine and tree-line lee features. Cooler temps overnight will have created a supportive crust to carry a person on skis, but this will likely break down by mid-day into isothermal, oatmeal-like slop from 2000m and below.
Avalanche Summary
Field teams yesterday were able to ski cut loose, moist size 0.5 avalanches on terrain over 30 degrees. 10-15cm soft slabs were reported on Video Peak, reactive to skier traffic to size 1.0. A notable recent avalanche was a glide crack release in Mounds path. on Sunday

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.
Loose Wet
Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
