This page provides access to charts of two standard fire danger indices from past years that are part of the National Fire Danger Rating System: Energy Release Component and Burning Index. Charts are created using NFDRS data from the Weather Information Management System and plotted against climatological information generated for each Southwest Predictive Service Area by FireFamily+. (Current year plots can be found at: SW NFDRS Charts.)
