Avoid wind-loaded alpine terrain. Natural and human-triggered wind slabs are possible.

Data is very sparse this time of year. Make observations as you travel and verify conditions.

No new avalanches have been reported in the White Pass area in the past few days.

On Sunday in Haines Pass, several large natural persistent slab avalanches were reported from northerly alpine terrain. See full details in this MIN report.

Based on last week's field observations, we do not suspect this layer is a concern in White Pass, but data is very sparse this time of year. Dig and investigate before committing to large, northerly alpine slopes.

10-20 cm of recent snowfall was accompanied by strong southerly winds, likely forming new wind slabs on north aspects.

The upper and middle of the snowpack contain several crusts.

Check out this recent MIN report from our field team for the most recent field observations.

• Be alert to conditions that change with elevation, aspect, and exposure to wind.
• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
