Document Description

The increasing complexity and impacts of fire seasons in the United States have prompted efforts to improve early warning systems for wildland fire management. A NIDIS-funded study led by the University of California-Merced demonstrated that subseasonal forecasts of fire danger from an experimental forecast system have significant skill at up to 3-weeks lead time across the contiguous United States.

Using hindcasts from 2011 to 2021, results show that while forecast skill degrades with time, statistically significant week 3 correlative skill was found for 76% and 30% of the contiguous U.S. for Energy Release Component and evaporative demand, respectively. This work was supported by grants from NIDIS, USDA, and the National Science Foundation.
