Kernpunkte

Backcountry travelers could trigger large avalanches today in a variety of areas, both above and below treeline. Some natural avalanches may occur. Consider avoiding avalanche terrain, especially in areas where clues to unstable snow are present, such as slopes filling in with wind drifted snow, near areas with snow surface cracking, or in the vicinity of recent avalanches.

The last daily forecast of the season is planned for Monday, April 13. We will provide intermittent General Avalanche Information bulletins through the end of April as conditions warrant.

    Rapid accumulation of new snow occurred last night and may occur again today. Ridgetop winds out of the SW have ranged in speed from strong to gale force/extreme over the past 24 hours. Look for clues of potentially unstable storm slabs, such as snow surface cracking, visible drifting snow, or recent avalanches. Consider avoiding avalanche terrain today, especially where signs of unstable snow are present.

    Expect to encounter areas of unstable snow today in both wind loaded and wind protected areas. Areas of wind loading may have extended below treeline last night due to the strength of the winds. Non-persistent weak layers may have formed within the new snow, which could allow for easy failures today within the new snow. Opting for slopes less than 30 degrees in slope angle without steeper connected terrain above or to the side can significantly reduce the likelihood of encountering an avalanche today.

    In the vast majority of areas, numerous hazards such as rocks, stumps, logs, etc are barely hidden under the recent new snow. Anticipate conditions similar to early season, where it is very easy to hit hard objects under the snow surface as you travel.

    Snow surface cracking is a sign of unstable snow in the area.

Avalanche Discussion

March and April's record setting heat and strong sun led to record setting snowmelt throughout the forecast area. Before this storm, continuous snow cover was generally limited to NW-N-NE-E aspect terrain above 7,500' to 8,000'. Large areas of bare ground were present on these aspects at lower elevations. With limited exceptions, SE-S-SW-W aspect terrain was mostly bare ground at all elevations before the current snowfall.
