Regions

Northwest Inland.

Warm and sunny weather means that hazard will increase during the day as the sun comes out and temperatures rise. For more information on managing spring melt-freeze conditions, click here

Avalanche Summary

The likelihood of loose wet avalanches on sun-affected slopes will increase throughout the day as the sun comes out and temperatures rise.

Snowpack Summary

Sun exposed slopes in the alpine and all aspects at treeline and below are becoming moist to wet during the heat of the day. In these areas, spring conditions are in effect; the avalanche hazard will fluctuate greatly depending on the strength of the overnight freeze and how quickly the snowpack is warmed up each day. Dry snow may still be found on shady slopes in the alpine. At these locations, 30-50 cm of well settled snow overlies a layer of facets (sugary snow) that was buried around March 10th.

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.
