Flurries will accumulate through the day. Use caution around ridge crests and lee terrain features, where the most reactive deposits will form.
Confidence
Moderate - Intensity of incoming weather systems is uncertain

Avalanche Summary
No new avalanches have been reported in the region. With spring conditions, the avalanche hazard will fluctuate greatly depending on the strength of the overnight freeze and how quickly the snowpack is warmed up each day, especially in areas with fresh snow.
Snowpack Summary
Flurries have fallen over high alpine terrain, wetter precipitation at lower elevations is keeping the snowpack moist and encouraging rapid melt below 1200 m.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
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.
