Regions

Olympics.

Most areas of the Olympics lack snow for avalanches. The only avalanche problem to be aware of on Tuesday should be possible loose wet avalanches, mainly on solar slopes, but possible on all aspects due to warm temperatures expected.

Detailed Forecast

An amplified upper ridge over the US and BC coastal waters will dominate the weather once again Tuesday, leading to sunny and warm conditions.

The only avalanche problem to be aware of on Tuesday should be possible loose wet avalanches, mainly on solar slopes, but possible on all aspects due to warm temperatures expected.

Otherwise little change is expected until significant new snowfall is received.

Snowpack Discussion

The meager amounts of snow left in the Hurricane Ridge vicinity are not currently creating an avalanche problem near or below treeline. South slopes at Hurricane are devoid of snow. On shaded or north slopes near and above treeline, there are up to a few feet of stable and consolidated rounded grains or melt forms and crusts.

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.
