The Bottom Line: Avalanche danger continues to decrease as mild temperatures and high cloud cover have helped the snow to gradually stabilize. That doesn’t mean you can’t trigger an avalanche Saturday. If you travel to higher elevations or into very steep terrain, you may find a lingering wind slab especially on convex slopes. As the sun comes out and temperatures warm, watch for rollerballs and fan-shaped avalanches that indicate you may experience a loose wet avalanche.

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.
