Weather Forecast

Continued high freezing levels Friday as Easterly winds provide upslope snow and /or rain Friday evening. A cooling trend for the weekend with current forecasts showing up to 30mm from Friday night to Sunday night possible. Snow should fall at higher elevations, but expect plenty of rain for a large part of the forecast period.

Snowpack Summary

The snowpack is enduring repeated freeze/thaw cycles with very high overnight freezing levels the past few nights. Avalanche danger predominantly relates to temperature, sun affect and surface crust integrity under these conditions (spring).

Avalanche Summary

No avalanches observed or reported today however afternoon loose/wet avalanches are a daily occurrence.

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.
