In sintesi

For most of today, avalanche danger is LOW for all elevations. Following arrival of the incoming storm, avalanche danger will increase to CONSIDERABLE during the evening and overnight hours at all elevations. Dangerous conditions will exist in the backcountry tonight and tomorrow with wind slab and storm slab avalanche problems expected.

    Prior to the onset of intense snowfall this evening or tonight, no specific avalanche problems are expected today. Any areas of wet snow encountered should be evaluated for the unlikely potential of loose wet avalanche problems. Any above treeline or near treeline areas of recently wind drifted or wind loaded snow should be evaluated for the unlikely potential of wind slab avalanche problems.

    Exercise normal caution while traveling in or below avalanche terrain by employing accepted best practices for travel in avalanche terrain. This includes communicating within the group to clearly identify slopes of concern, exposing only one person at a time to slopes of concern, and moving from identified safe zone to identified safe zone.

    Dangerous avalanche conditions are expected to develop at all elevations this evening, through the overnight hours, and continue well into Thursday. The approaching storm is expected to create widespread wind slab and storm slab avalanche problems.

Avalanche Discussion

Observations were made yesterday on Incline Lake Peak (Mount Rose area) and on Armstrong Pass (near Freel Peak). Melt-freeze crusts are widespread on the snow surface in most areas. Isolated patches of unconsolidated snow linger from the last storm in shaded areas, generally on northerly aspects. Areas of wet snow were reported yesterday in the Armstrong Pass area below 9,000' with no signs of loose wet instabilities. On Incline Lake Peak, snowpit data collected adjacent to a small (size D1) wind slab avalanche that appeared to have occurred on April 10 produced mixed results with minimal evidence indicating any potential ongoing wind slab instability.
