The Objective Drought Tendency Forecast is an integrated product that combines information from the flash drought development tool and subseasonal Standardized Precipitation Index (SPI) 3-month forecasts. The latest U.S. Drought Monitor is used as initialization, and the product synthesizes information through a decision-tree process to determine drought tendency categories for the upcoming month. The forecast product started running on April 1, 2019, and updates daily. This tool is used to inform the official forecasts.
