Snowpack Summary

A spring snowpack is rain soaked and contains several crusts. Very high N alpine may hold dry snow if you can get there. Check out this link for more info on spring conditions. Expect the forecasted rain and warm temperatures to continue to destabilize the snowpack.

Avalanche Summary

A natural sz 2.5 was observed this morning from Cougar Creek West and a few infrasound detections suggest natural activity with the rain. Cornice falls and glide slabs have been releasing more frequently recently.

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.
