Glacier.
Expect thin soft slabs in immediate lee alpine areas with today's snowfall.
Weather Forecast
Flurries with an accumulation of 8-15 cm today, accompanied by moderate winds from the SW. Freezing levels are forecast at 1600 m with an alpine high of -4C. The rest of the week looks like a mix of sun and cloud, no more precipitation, and freezing levels around 1800 m.
Snowpack Summary
Temperatures have dipped below 0 at treeline and above for the first time in a week. Expect to find a variable crust in the morning, which may break down into moist snow by the afternoon. Isothermal conditions exist below tree line. Cool dry snow exists on high Northerly aspects.
Avalanche Summary
The natural spring avalanche cycle has continued for over a week now, and produced numerous wet loose avalanches yesterday to sz 3 on primarily north aspects in the alpine and at treeline. Explosives control missions last week produced numerous avalanches on all aspects. A notable recent avalanche was a glide crack release in Mounds path. on Sunday

Problems
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.
Persistent Slabs
Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
