State of the Climate Monthly Overview - Drought

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Drought report describes conditions in the United States, including Puerto Rico and the U.S. Affiliated Pacific Islands as warranted. A national drought overview is provided with detailed discussion on various regions. Several indices are presented: Palmer drought indices, Standard Precipitation Index, and other agricultural and hydrological indices. State, regional, and national moisture and precipitation status with historical rankings are available. Content of individual reports varies somewhat according to conditions and data availability. Reports were issued sporadically in 1999 and early 2000, with regular monthly reports beginning in September 2000. Annual reports are available from 2002.
