What drought has meant in Tennessee

The National Drought Mitigation Center's examples of impacts observed in Tennessee at each level of drought, starting with this week's worst here.

D0 Abnormally dry This week

  • Honey production is down; fewer plants are available to pollinate
  • Lake and pond levels begin to lower

D1 Moderate drought

  • Agriculture ponds dry up; farmers are hauling water; hay yield is low
  • Conditions are very dusty
  • Fire danger increases; burn bans are implemented
  • Leaves fall early
  • More insects and voles are observed, although mosquito numbers are down; disease spreads in trout, fish hatchery closes
  • Water demand is high

D2 Severe drought

  • Air quality is poor; burn bans are implemented; active wildfires are reported
  • Aquatic species die off
  • Corn is severely stressed; producers are importing hay and selling livestock
  • Streams and creeks are extremely low or dry; well levels are lowering
  • Voluntary water conservation is requested; water quality is poor

D3 Extreme drought

  • Water supply is inadequate for wildlife

D4 Exceptional drought

  • Large wildfires are reported

Drawn from the Drought Impact Reporter and local observers.

Burn bans and water restrictions

The Drought Monitor does not issue burn bans or water restrictions. Sullivan County's officials, the state forestry or fire agency, and local water utilities set them, often once drought reaches D2 or dry fuels raise the fire danger. Check the county's emergency management office or fire marshal for a ban in force, and the alerts page for red flag warnings and fire weather watches.

This week in the South

The Drought Monitor authors' narrative for the map of Sep 29, 2026, released Oct 1, 2026.

The southern states have taken the brunt of recent drought intensification since August, which continued this past week across most of Oklahoma and Texas. Worsening drought also occurred across most of Arkansas, Louisiana, Mississippi, and Tennessee. Virtually no rain fell this past week in this region except for far western Texas, the Oklahoma Panhandle, and eastern Tennessee. Combined with temperatures of 6-12 degrees above average, the lack of rainfall contributed to the rapid intensifying drought. Most of central and eastern Texas, Oklahoma, and Arkansas are under severe, extreme, or exceptional drought classifications. Louisiana, Mississippi, and Tennessee are quickly degrading as well into severe to extreme drought conditions due to the September heat wave and continued lack of rainfall. Much of Texas and Oklahoma need to receive 20 to 25 inches of rainfall over a 3-month span to break out of the present drought. The lone exceptions to the drought worsening were in far western Texas and the western Oklahoma Panhandle, where several inches of rain fell as eastern Pacific tropical moisture associated with Hurricanes Odalys and Polo moved across the region. Far eastern Tennessee experienced temperatures around 3 degrees below normal along with the plentiful rainfall resulting in no drought conditions.

Looking ahead

Ongoing substantial rain was falling Tuesday morning at the onset of the new U.S. Drought Monitor week, from Arizona and New Mexico into the Central and High Plains. This excessive rainy system connected to Hurricane Polo is projected to continue eastward this week into the High Plains, Midwest, and South regions. The Weather Prediction Center has moderate threats for excessive rainfall from the Southwest into Texas, Oklahoma, northward into Nebraska and Iowa. Drought-busting rains may be possible across the South as this weather system evolves this week. Looking into the next week, the Climate Prediction Center’s 6–10-day outlook indicates that well-above average temperatures will shift into the western states, along with below normal precipitation chances. Meanwhile, above average precipitation chances are projected from southern Texas into the southeastern states, including Florida. Above average precipitation chances are also projected for southeastern Alaska, with near neutral rainfall forecasts for Hawaii.

What this means

The five categories the Drought Monitor draws, and how the map is made.

D0 Abnormally dry
Going into or coming out of drought.
D1 Moderate drought
Some damage to crops and pastures; water shortages developing.
D2 Severe drought
Crop or pasture losses likely; water restrictions imposed.
D3 Extreme drought
Major crop and pasture losses; widespread water shortages.
D4 Exceptional drought
Exceptional and widespread losses; water emergencies.

The US Drought Monitor is drawn every week by authors at the National Drought Mitigation Center, USDA and NOAA, who weigh rainfall, soil moisture, streamflow, groundwater, vegetation health and reports from local observers. Each map shows conditions through Tuesday morning and is released on Thursday. It shows where drought is and how bad it is; it does not forecast it. CPC's outlooks do that.
