Ice climbers are especially vulnerable to wet slides from above because of longer exposure times; chose your climbs carefully.
Weather Forecast
Strong solar effect, with clear skies forecast for Friday. An inversion has kept higher elevations above freezing, with no overnight cooling to help the recovery and stabilization of a stressed snowpack. Freezing levels will remain over 3000m. Cooling and some precip, likely in the form of rain initially, is forecast starting Saturday evening.
Snowpack Summary
Spring snowpack on solar aspects, with minimal crust recovery overnight rapidly breaking down under daily intense solar input. The entire snowpack is isothermal below treeline on solar aspects. The snowpack remains dry on shady aspects at upper elevations, but may become reactive with continued warm temps.
Avalanche Summary
Many solar aspects at TL and below have slid and continue to slide around the forecast region. Nearly no activity has been observed on Northern aspects, especially in the Alpine.
Confidence
Freezing levels are 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.
Wet Slabs
Wet Slab avalanches are the release of a cohesive layer of snow (a slab) that is generally moist or wet when the flow of liquid water weakens the bond between the slab and the surface below (snow or ground). They often occur during prolonged warming events and/or rain-on-snow events. Wet Slabs can be very unpredictable and destructive.
