Avalanche Summary

No new avalanches have been reported recently. However, warming signs of instability, such as pinwheels and tree bombs, were observed earlier this week.

If you are going out in the backcountry, please consider filling out a Mountain Information Network (MIN) report.

Snowpack Summary

A melt-freeze crust has likely formed at the snow surface with overnight cooling. Rising temperature will start to melt the snow surface, as the day progresses, especially on steep sun-exposed slopes.

At upper and mid-elevations, the snowpack is moist to ground.

Snow depths vary across the region. Currently, near Mt. Washington, 135 cm is reported at 1100 m, and 250 cm at 1500 m.
