Drought Risk Atlas

Description

This site helps people answer the question “How does this drought compare to previous droughts?” 

Site visitors can examine a continuous record of weather data and drought indices computed for more than 4,000 locations across the United States. As not every drought index is ideal for every location, available products include pre-generated heat maps, time series, tabular analyses, and more for the Standardized Precipitation Index, the Standardized Precipitation and Evapotranspiration Index, the Palmer Drought Severity Index, the self-calibrated Palmer Drought Severity Index, the Standardized Streamflow Index, and more.
