Warm overnight temps and showery weather today will keep conditions touchy. Be prepared to adjust your objectives; conditions will change rapidly in the coming days with an unsettled forecast and the warm spring snowpack.
Weather Forecast
A series of cool and moist weather systems move through the region over the next few days. Today expect showers/flurries with freezing levels at 2000m, moderate SW winds and a few sunny breaks. Thursday will be similar but slightly warmer with alpine temps of +3'C. On Friday expect a mix of sun and cloud, with freezing levels lowering to 1800m.
Snowpack Summary
There was no overnight recovery last night, and it is presently raining to at least 1900m. The snowpack on solar aspects is moist and composed of multiple crusts, while on sheltered north aspects dry snow can still be found above ~2100m. A 30-60cm slab over a crust on solar aspects and surface hoar on North aspects remains a concern.
Avalanche Summary
Yesterday strong solar and warm temps continued to trigger numerous loose and slab avalanches from all aspects other than due North, starting at elevations ranging from 1800m to 2600m. Most of the wet avalanches were 2.5's but there were a few size 3's, including another size 3 glide crack release.
Confidence
Timing, track, or intensity of incoming weather system is uncertain
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.
