General Spring Avalanche Statement

The 2019-2020 operating season has come to a close. Thank you to everyone who supported the avalanche center this season, making everything possible. Avalanche activity will continue to occur this spring. Expect wet snow instabilities and cornice failures on warm days. When spring storms impact the region, they bring the possibility of fresh slabs of wind drifted snow and storm slabs. Keep reading for some information and resources to aid in trip planning and decision making.

A good overnight refreeze and cooler windy weather will mean firm snow surfaces this morning. As the day warms up and the refreeze melts, avalanches of loose wet snow may become possible on steep sunny slopes this afternoon. Cornice fall will also remain possible. This afternoon MODERATE avalanche danger will form at all elevations. This is the last avalanche forecast for the season.

Firm surfaces, breakable crusts, and continued NE winds will continue to vex backcountry travelers today. Mostly frozen snow surfaces and very little new snow for the wind to blow around should keep significant avalanche activity unlikely today. LOW avalanche danger exists at all elevations.

While blowing snow may be present today, significant avalanche activity should remain unlikely since old snow should remain frozen and new snow accumulation should remain limited. Variable firm snow conditions and gale force NE winds represent the main challenges for backcountry travelers today. LOW avalanche danger exists at all elevations.

Firm icy surfaces on exposed slopes and variable conditions on sheltered slopes will represent today's main concerns for backcountry travelers. Significant avalanche activity should remain unlikely due to the limited amount of new snow that accumulated. LOW avalanche danger exists at all elevations.

Shallow, difficult to trigger slabs of wind drifted snow exist near treeline and above treeline. Warming conditions and snow surface melt will allow for rollerballs and maybe some small loose wet avalanches. Isolated small avalanches may occur today, well within the definition of today's forecast of LOW avalanche danger for all elevations.

High winds will continue today with blowing snow.  Human triggered wind slab avalanches will remain possible.  MODERATE avalanche danger will exist in near and above treeline terrain with LOW avalanche danger in below treeline areas.

Slabs of wind drifted snow that fail in response to a person recreating on a slope remain possible today in wind-exposed areas in near and above treeline terrain. Avalanches on the Jan 4 persistent weak layer have moved into the unlikely but not impossible category. If they did occur they would have serious consequences. Avalanche danger is MODERATE for all elevations.

Slabs of wind drifted snow at upper elevations and sluffs of wet snow at lower elevations are possible today. New loading on the persistent weak layer of crust and sugary faceted snow means that higher consequence avalanches may also be possible today. Avalanche danger is MODERATE for all elevations.
