Regions
Northwest Coastal.
Warm and sunny weather means that hazard will increase during the day as the sun comes out and temperatures rise.

Avalanche Summary
When the sun comes out and temperatures rise during the day, loose wet avalanches will be possible on sun-affected slopes.On Friday, there were reports of a few size 2 loose wet and wet slab avalanches on southerly aspects.
Snowpack Summary
Sun exposed slopes in the alpine and on 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 remain on shady slopes in the alpine. In these locations, 50-100 cm of snow sits on 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.
