Minimize exposure to steep slopes as temperatures warm through the day, especially in areas with fresh snow.

Avalanche Summary
If the sun comes out for prolonged periods of time or as temperatures rise, the chances of loose avalanches will increase, especially in areas with fresh snow.On Monday, small (small 1-1.5) loose-dry and loose-wet avalanches were reported with the accumulated snowfall as well as two small (size 1-1.5) storm slab avalanches triggered with explosives. On Tuesday, snowballing was observed in alpine terrain.
Snowpack Summary
About 5 cm recent snow overlies a thick crust on most aspects and elevations. On north-facing, alpine terrain, up to 20 cm recent snow is bonding well to a cold, dry snowpack. Lower down in the snowpack, the base is composed of weak facets (sugary snow). In areas that remained more sheltered from the heat (like north-alpine), human triggering of persistent slabs on this layer may still be possible; especially in rocky alpine terrain with a shallow or highly variable depth snowpack.The snowpack on sun-exposed slopes in the alpine and all aspects at treeline and below may become moist or wet during the heat of the day, especially if the sun comes out. 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.
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.
