Since early 2020, the Southwest United States has suffered record low precipitation and near-record high temperatures, gripping the region with an unyielding, unprecedented, and costly drought. This exceptional drought—marked by massive water shortages, destructive wildfires, emergency declarations, and the first ever water delivery shortfall among the states sharing the Colorado River—punctuates

The 2017 Northern Plains drought sparked wildfires, destroyed livestock, and reduced agricultural production. Neither the drought’s swift onset nor its severity were forecasted. In May 2017, the region was mostly drought-free, and at least average summer precipitation was forecasted. By July 2017, North Dakota, South Dakota, eastern Montana, and the Canadian prairies were experiencing severe to

Drought can have a significant impact on the management and operations of water utilities, from loss of water supply and poor source water quality to increased demand from customers and reduced revenues. Changing conditions in precipitation, snowpack, soil moisture, temperature, and evapotranspiration must be well monitored and better forecasted to provide water managers early warning of drought

The Evaporative Demand Drought Index, also known as EDDI, is an experimental drought monitoring and early warning tool that looks for drought using atmospheric evaporative demand (also known as the “thirst of the atmosphere”). So far, EDDI maps and data have been made available for near-real-time and historical monitoring; now, with the help of the NOAA-National Centers for Environmental
