Historical and Future Snow Trends (Map Service)

Published by U.S. Forest Service | Department of Agriculture | Metadata Last Checked: January 27, 2026 | Last Modified: 2025-10-27
The National Forest Climate Change Maps project was developed to meet the need of National Forest managers for information on projected climate changes at a scale relevant to decision making processes, including Forest Plans. The maps use state-of-the-art science and are available for every National Forest in the contiguous United States with relevant data coverage. Currently, the map sets include variables related to precipitation, air temperature, snow (including April 1 snow water equivalent (SWE), and snow residence time), and stream flow.
