The likelihood of wet loose avalanches will increase with each successive day of warm weather.
Monitor the conditions and back off steep slopes as the surface becomes wet or slushy.

Moderate
Avalanche Summary
No new avalanches have been reported in the last 2 days. With rising temperatures, we expect that wet loose avalanches will become more likely. Warming signs of instability such as tree bombs and pinwheels were observed throughout the region this weekend.
If you are going out in the backcountry, please consider filling out a Mountain Information Network (MIN) report.
Snowpack Summary
Rising freezing levels will start melting the surface snow. Expect this wet layer to get deeper as the trend continues for the next few days.
Up to 30 cm of snow at upper elevations may be covering surface hoar on sheltered features and a sun crust on steep south-facing terrain.
We are not tracking any concerning weak layers in the mid or lower snowpack at this time.
Snow depths vary across the region. Currently, near Mt. Washington, 135 cm is reported at 1100 m, and 250 cm at 1500 m.

Terrain and Travel Advice
- A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
- Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
- Loose avalanches may start small, but they can grow and push you into dangerous terrain.
Problems
Loose Wet
No overnight refreeze and rising temperatures are making wet loose avalanches more likely. Uncertainty remains on how quickly the snowpack will weaken.
