Avalanche Summary
No new avalanches were reported on Sunday. If you have any recent observations during your travels, we would greatly appreciate it if you posted a photo or any other information to the Mountain Information Network (MIN). Thanks!
Snowpack Summary
Around 30 cm of recent snowfall has likely been blown around by southerly wind, which overlies a melt-freeze crust. This recent snow should remain dry above 1500 m on northerly aspects but will otherwise moisten with an increasing freezing level and sunny periods. The snowpack is rapidly melting below 1200 m.
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.
