    Drought in Tennessee

    The Southeast region generally receives substantial precipitation and is often considered water-rich. However, droughts are not uncommon, and the Southeast has a long history of multi-year droughts, including the recently experienced record-breaking droughts of 2006–2008 and 2010–2012. Tennessee also experienced a high impact drought in 2016 that was a primary factor in several major wildfires, including the Gatlinburg wildfires that resulted in loss of life and widespread infrastructure damage. These droughts had far-reaching impacts on agriculture, water availability for municipalities and industry, and wildfires.

    Drought conditions can also develop rapidly in the Southeast, especially when the lack of rain and high temperatures combine to quickly increase the loss of water from the landscape via evapotranspiration. There is increased regional awareness of how these rapid-onset droughts, sometimes referred to as ‘flash droughts’, can cause significant agricultural economic impacts. A recent example of flash drought in Tennessee occurred in the late summer and early fall of 2019. Drought is expected to increase in the Southeast due to a combination of higher temperatures, as well as increased population, industry and urban land use region, which will further affect water resource recharge and amplify competing water demands in the region.

    NOAA’s National Integrated Drought Information System (NIDIS) launched the Southeast Drought Early Warning System (DEWS) in 2020, which includes Alabama, Florida, Georgia, North Carolina, South Carolina, Tennessee, and Virginia. The Southeast DEWS is a network of regional and national partners that share information and coordinate actions to help communities in the region cope with drought.

    Reach out to Meredith Muth, the Regional Drought Coordinator for this region, for more information, or sign up for the Southeast DEWS newsletter.

    Historical Drought Conditions in Tennessee

    Drought is a normal climate pattern that has occurred in varying degrees of length, severity, and size throughout history. Below, you can look back at past drought conditions for Tennessee according to 3 historical drought indices. The U.S. Drought Monitor is a weekly map that shows the location and intensity of drought across the country since 2000. The Standardized Precipitation Index (SPI) is a monthly depiction of drought based on precipitation (with data going back to 1895). And the paleoclimate data uses tree-ring reconstructions to estimate drought conditions before we had widespread instrumental records, going back to the year 0 for some parts of the U.S. View more historical conditions.

    The U.S. Drought Monitor (2000–present) depicts the location and intensity of drought across the country. Every Thursday, authors from NOAA, USDA, and the National Drought Mitigation Center produce a new map based on their assessments of the best available data and input from local observers. The map uses five categories: Abnormally Dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought (D1–D4). Learn more.
