On this episode of the 603podcast, Charlotte MacDonald talks with host Dan Egan and opens a window into the work of the Mount Washington Avalanche Center, where life-saving forecasts are crafted in pre-dawn darkness and tested daily against the mountain's unpredictable temperament. Rising at 4:30am to analyze weather data, MacDonald collaborates with fellow forecasters to publish early a.m. advisories that backcountry enthusiasts depend on before heading into avalanche terrain.

The White Mountains present unique forecasting challenges with wind-driven snowpacks that transform hourly. "In some ways it's easy to get into our terrain," MacDonald explains, "but it's also challenging." Unlike static snowpacks in other regions, Mount Washington's snow constantly shifts with hurricane-force winds that alternately stabilize and destabilize slopes. This dynamic environment requires forecasters to develop intimate knowledge of how wind, temperature, and precipitation interact across the mountain's complex terrain.

MacDonald's journey from recreational skier with little avalanche knowledge to professional forecaster offers a compelling narrative about the importance of education and mentorship. Today, she's pioneering mentorship programs to help others develop crucial safety skills, emphasizing that education shouldn't end with a basic avalanche course.

The increasing popularity of backcountry skiing has transformed the forecaster's role beyond simply predicting avalanche conditions. As more adventurers explore remote terrain year-round, MacDonald and her colleagues balance forecasting duties with search and rescue responsibilities, community education, and cultivating a culture of information sharing. Her simple request? Send photos and observations from your adventures—they provide vital data that might save lives.

Whether you're an experienced backcountry traveler or simply curious about how avalanche professionals protect mountain communities, this conversation offers rare insight into the elements behind every forecast.
