You may notice a couple of changes to the web advisory today. We frequently refer to the snowplot at Hermit Lake in our advisory but will be including the raw data which is collected every morning by the caretaker at the AMC operated facility there. You need to go to the full forecast to see the data and wind chart. As resources allow, we plan to roll out more of this type of data to help you make more informed decisions when venturing into avalanche terrain. The weather data provided by our partners at the Mount Washington Observatory continues to be critical to our forecast process but more data improves our accuracy and may prove helpful to the dawn patrol skiers and climbers out there. Special thanks to the AMC caretakers for getting up early to collect the data, Chris McKnight for the wind rose and High Charts for providing a free license.
Join us this Saturday, March 17, at 5pm at International Mountain Equipment (IME) for the third installment in the White Mountain Avalanche Education Fund’s Continuing Education Series. Helon Hoffer will be reviewing fracture mechanics and exploring fracture arrest. We’ll be looking at the big wind slab avalanche that occurred on February 8 throughout the talk and discussing why the slab boundary stopped where it did. While this talk may raise more questions than answers, it will help give a better understanding of why dry slab release occurs the way it does.
Harvard Cabin will be temporarily closed mid-week due to a staffing shortage. The cabin will be open Friday and Saturday nights. This closure includes tenting outside the cabin. For those interested in overnighting in the Cutler River Drainage, you may do so at Hermit Lake Shelters. We will provide updates to this closure on our website or you may contact the AMC Pinkham Notch Visitor Center at (603) 466-8116 to see if there is availability.
The White Mountain Avalanche Education Foundation and the NHOC are sponsoring a Mountain Weather Workshop in North Conway, NH. Senior Forecaster and Education Specialist Mike Carmon, of the Mount Washington Observatory, will be teaching topics relevant to avalanche forecasting and mountain travel in the White Mountains.
Topics will include weather variables and measurement, mesoscale and synoptic scale features, case studies on winter storms and forecasting challenges such as Norlun Troughs, Nor’easters, Alberta Clippers, Upsloping Events and more.
Registration is limited in number with scholarship seats available for $40 awarded by nomination to 2 members of each local rescue team. More seats will be available to people unaffiliated with local teams for $80.
The class is 16 hours long and spread over the following dates:
- Wednesday, February 21, 5-9pm at IME
- Friday, February 23, 5:30-9pm at the MWObs Weather Discovery Center (WDC)
- Wednesday March 7, 5-9pm at the MWObs WDC
- Wednesday March 21, 5-9pm at the MWObs WDC
Proceeds of the course will benefit the White Mountain Avalanche Education Foundation.
Strategic Field Observations
CT22 Q1 SC, ECTP27, PST 60/100 End, no whumphing, some shooting cracks, I see wind blowing snow around, I have to push kinda hard to make a hand shear fail… What does this all mean? CAN I SKI IT?
We have these stability assessment tools and many more at our disposal. They’re all supposed to ultimately guide our “Go” and “No Go” decisions. Is this a simple process? No. Do you find it challenging? You’re not alone. Can we all get better at interpreting stability test results and snowpack observations? Yes.
A snowpack is constantly changing and we have a variety of avalanche problems to contend with every season. Varied conditions require a varied approach to snow stability assessment. Join us to dive into this topic at a FREE event this Saturday evening. We’ll use stability tests and other familiar snow stability assessment tools as a starting point in a deeper discussion about letting conditions dictate your observation strategies.
Strategic observations can help any of us make better decisions in the mountains. It’s all about having more good days and coming home in one piece. See you Saturday evening!

White Heat Tracks Project seeks your input:
The aim of the White Heat Project is to generate new and usable knowledge on risk-taking behavior, and on factors behind decision errors in avalanche terrain in particular. The White Heat Tracks project is an extension to the previous “SkiTracks” project, and is a collaboration between a group of researchers at UiT The Arctic University of Norway, in Tromsø; Montana State University, in Bozeman, USA; and Umeå University, in Umeå, Sweden. We are asking people to complete a decision-making survey: (https://montana.qualtrics.com

Huge thanks to volunteers Paul Bazanchuk, Ryan Brouder & Terran Siladi for helping us with this battery bank/inverter setup donated by the Friends of Tuckerman Ravine.
The White Mountain Avalanche Education Foundation, along with the Mount Washington Avalanche Center, is bringing back the Avalanche Education Continuing Ed Series at IME this winter. They will take place the 3rd Saturday of January (20th), February (17th) and March (17th). Come by IME at 5 pm to hear the MWAC Snow Rangers share the state of the snowpack, avalanche center and different topics each month. As you’re heading back from the mountains, stop by IME and feel free to bring your own beverages and food. MWAC Director and Lead Snow Ranger, Frank Carus, will be leading the first presentation on January 20th. He will discuss Avalanche Problems and Terrain Management as well as aprovide an Avalanche Center and Forecasting Update. We’ll see you there!
