In Alaska, increased wildfire activity has been linked to warming temperatures. Summers with extreme wildfire activity threaten life and property, clog the air with smoke, and challenge the state’s wildland firefighters. While the largest fires are often started by lightning and burn in remote areas, these fires require significant resources to fight when they threaten life and property. Increased wildfire activity is projected to continue in Alaska, as climate conditions change. Therefore, understanding how to best calculate fire risk based on short and long-term weather conditions is needed to improve fire season forecasts. Currently, Alaska’s fire managers rely on the Canadian Forest Fire Weather Index to monitor...

Abstract (from Earth Interactions): Parts of southeast Alaska experienced record drought in 2019, followed by record daily precipitation in late 2020 with substantial impacts to human health and safety, energy resources, and fisheries. To help ascertain whether these types of events can be expected more frequently, this study investigated observed trends and projected changes of hydroclimatic extremes indices across southeast Alaska, including measures of precipitation variability, seasonality, magnitude, and type. Observations indicated mixed tendencies of interannual precipitation variability, but there were consistent trends toward warmer and wetter conditions. Projected changes were assessed using dynamically...
