Avalanche Summary
Saturday: Small loose wet avalanches were observed releasing out of steep, rocky terrain around treeline, near Mt. Washington
Friday: The field team reported seeing numerous small loose wet avalanches in the Mt. Arrowsmith area. For more details check out their MIN.
With the current warm and very wet conditions hitting the Island, we suspect a cycle of loose wet avalanches will continue.
Snowpack Summary
Rain has saturated the snowpack right to mountaintop elevations, melting out the snowpack below treeline almost entirely, and leaving it mostly below the threshold for producing avalanches.
We suspect what remains of the snowpack at upper elevations is mostly isothermal.
The potential for loose wet avalanches to release due to continued heavy rain and warm temperatures continues.

Terrain and Travel Advice
- Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
