New information will be issued when conditions warrant.

The Bottom Line

Mount Washington Avalanche Center released the final avalanche forecast, after a cool and snowy spring, on June 8th, 2020. We will begin forecasting for the 2020-21 season when the snow starts flying again in the fall. Until then, look for information on a virtual Eastern Snow and Avalanche Workshop here and on our social media channels. Until then, enjoy your summer!

Please Remember:

Safe travel in avalanche terrain requires training and experience. This forecast is just one tool to help you make your own decisions in avalanche terrain. You control your own risk by choosing where, when, and how you travel.

Avalanche danger may change when actual weather differs from the higher summits forecast.

For more information contact the US Forest Service Snow Rangers, AMC visitor services staff at the Pinkham Notch Visitor Center, or the caretakers at Hermit Lake Shelters or seasonally at the Harvard Cabin (generally December 1 through March 31). The Mount Washington Ski Patrol is also available on spring weekends.
