The Mount Washington Avalanche Center will no longer issue daily avalanche forecasts for the 2020/21 season. Instead, we will post an updated General Avalanche Information statement as needed, if significant snow or weather events that might vary from the typical daily changes that come with spring weather. We will also keep you informed about the official closure of the portion of the Tuckerman Ravine Trail where it passes by Lunch Rocks and through the Lip and above the Headwall. Observations from the field will continue to be a valuable resource, so please keep submitting photos, videos and observations here and we will do the same.
The switch to General Avalanche Information from a daily Avalanche Forecast does NOT mean that the mountains are now free of avalanches. If you spent much time in the mountains here, you understand how quickly wind slabs develop with just a few inches of snow and the legendary Mount Washington wind and terrain configuration. Be sure to keep a close eye on the weather forecasts linked below and pick your days carefully.
New snowfall and winter conditions are possible during any month of the year at higher elevations in the Presidential Range. One tool to help reduce the chance for unwelcome surprises due to snowfall, icing conditions or just raw, hypothermia weather is the weather record produced by MWObs summit staff. The NWS displays the summit hourly data here with hourly data from Hermit Lake shown here. Spring and early summer bring rapid changes to our upper snowpack, with conditions often changing by the hour. Plan accordingly for these changes by reading the weather forecast before you head out (MWObs Higher Summits and NWS Hourly forecast).
