Flash droughts have severe impacts and occur when regular drought conditions rapidly intensify. This makes it more urgent to accurately identify the physical processes behind their origins. Early-warning systems (EWS) that could identify trends in climate and sources of water were needed to detect the emergence or probability of the occurrence.

The lowest level of drought is labeled D0 and the worst and highest level is D4. The Drought Monitor defines D4 this way: Boat ramps close; trout fishing limits are lifted; wildlife populations decline; producers haul water for wildlife; ecosystem viability is threatened.
