Midwest Drought Early Warning System

Precipitation extremes in the Midwest have a major impact on the region’s resources, economic sectors, and residents. Over the last century, precipitation trends in the Midwest have been moving towards wetter conditions and fewer droughts than the region experienced in the early 20th century. However, the Midwest has still felt adverse impacts during recent droughts, particularly in 1988 and 2012. These adverse impacts include limited barge transportation on major rivers (including the Mississippi River), decreased agricultural production, challenges for municipal water supply and quality, and reduced productivity for hydropower. An added challenge in recent years has been the tendency to transition from drought to flood and back to drought within short time spans, sometimes within a matter of months. NIDIS and its partners launched the Midwest DEWS in response to the 2012 drought, which highlighted the need for additional drought early warning and preparedness in the region.
