Snowpack Summary

A rain soaked snowpack is capped by a thick (15cm at Rogers Pass) surface crust this morning. Very high N alpine may hold dry snow if you can get there. Check out this link for more info on spring conditions.

Avalanche Summary

Yesterday, a few large glide avalanches, up to size 3.0, released from the north side of Mt Macdonald, the south side of Mt Tupper, and the east side of Cougar Mountain. Several loose wet avalanches to size 2.5 were observed Friday through yesterday on all aspects, triggered by rain and warm temperatures.

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.
