Snowpack and Avalanche Information for Friday, May 08, 2020
This information was published 05/08/2020 at 7:34 AM.
Despite the date on the calendar, new snowfall and winter conditions have returned to higher elevations in the Presidential Range. A cold front followed by a coastal storm will bring upslope snowfall, cold temperatures and high winds to the alpine. Plan accordingly for these changes by reading the weather forecast before you head out (MWObs Higher Summits and NWS Hourly forecast).
One tool to help reduce the chance for unwelcome surprises is the hourly weather information produced by MWObs summit staff. The NWS displays the hourly data going back 7 days here.
Recent snowfall earlier this week was underwhelming and did not do much more than create some thin pockets of new snow over a hard surface. Some recreational ski traffic is finding a mix of hard, edgeable surface up high with softening snow at middle elevations. Travel conditions in a single day could vary from the need for floatation in rotten lower elevation snow to crampons and ice axes on hard névé.
Overall, there’s still lots of snow at mid and upper elevations with few of the typical spring crevasse, moat and icefall hazards yet to emerge. This means there are expansive and connected slopes which could produce large avalanches if the upper reaches of snowfall totals pans out. Don’t put away your beacon just yet!
Keep the following spring mountain hazards in mind as you make terrain decisions:
The Sherburne and Gulf of Slides ski trails are no longer entirely snow covered to Pinkham Notch with water bogs rocks and dirt below around 3,000′. That said, a rescue litter will slide easily all the way to the parking lot with 4-5 rescuers.
Details on daily snowfall totals, precipitation type, total depth of snow and other information can be found on our page devoted to snow study plot data. Click here to check it out.
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.
