An underwhelming storm will tapper off this morning.Avalanche hazard will increase with daytime warming, especially if the sun has a chance to make an appearance on solar aspects.
Weather Forecast
A delightfully typical Selkirk spring day with mainly cloudy skies, periods of sun and convective flurries. Expect an alpine high of -7 with valley bottoms rising above zero as the freezing level reaches 1500m. Winds will be from the west in the 25-50km/hr range. Clearing skies for Wednesday and Thursday.
Snowpack Summary
10cm of new snow in the past 24hrs brings the weekly storm snow amount to 55cm. The storm snow is moist and sits on a crust up to 1900m on all aspects and seems to be bonding well. The mid and lower pack is well settled and strong.
Avalanche Summary
Numerous loose wet avalanches yesterday size 2-2.5 occurring below 2100m, along with a size 3 glide crack, which stopped ~100m from the highway.Several glide cracks are opening up in our area and are unpredictable in nature. Avoid these hazards as the results will be large and destructive.Avalanche Control today, check DriveBC for more information
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.
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
