Regions

Olympics.

The avalanche danger will be listed as low at all levels in the Olympics zone due to low snow cover.

Detailed Forecast

Partly cloudy weather with a slight chance of a few light rain showers should be seen this evening to Thursday morning. Most areas will see no precipitation. Decreasing clouds should be seen Thursday afternoon and night. Winds will be light with a slow warming trend.

This weather will cause little change in snow conditions and an overall low danger. The avalanche danger will be listed as low at all levels in the Olympics zone due to low snow cover. The only limited avalanche problem to watch for should be loose wet avalanches above treeline. But the likelihood and size will be listed as unlikely and small respectively

Snowpack Discussion

Last weekend a warm front caused high snow levels and rain. At Hurricane this wiped away snow from January 18th and 19th.

Warm weather and some sunny weather Sunday to today further melted away remaining snow. 

NWAC pro-observer Katy Reid visited Hurricane on Sunday and reported very low snow cover with snow-free areas on solar slopes. There were no avalanche problems near and below treeline due to lack of snow. 

Katy also ventured toward Mt. Angeles. She found snowdepths averaging 40-80 cm on N aspects with a few drifts above 1 meter. Snow cover was patchy only a few hundred feet below the ridge even on N slopes. This snow was well bonded consisting of melt forms and crusts and did not pose an avalanche problem.

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.
