Current Conditons

The Southwest and western parts of the Central and Southern Plains have been dry and windy (with extreme heat in Texas). Together, you get a major expansion of Extreme (D3)/Exceptional (D4) Drought in these regions. As of May 17, 2022, 43.98% of the U.S. and 52.54% of the lower 48 states are in drought.

 

U.S. Drought Monitor

The U.S. Drought Monitor (USDM) is updated each Thursday to show the location and intensity of drought across the country using a five-category system, from Abnormally Dry (D0) conditions to Exceptional Drought (D4).

The USDM is a joint effort of the National Drought Mitigation Center, USDA, and NOAA. Learn more.

The USDM Change Map shows where drought has improved, remained the same, or worsened since the previous week's Drought Monitor. Learn more.

Evaporative Demand (EDDI)

The Evaporative Demand Drought Index (EDDI) is an experimental drought monitoring tool that can serve as an indicator of both rapidly evolving "flash" droughts and sustained droughts. It examines how anomalous the atmospheric evaporative demand (E0; also known as "the thirst of the atmosphere") is for a given location and across a time period of interest. EDDI can offer early warning of agricultural drought, hydrologic drought, and fire-weather risk. Learn more.

Precipitation Conditions

The current precipitation conditions show the precipitation accumulation for the last 7 days using the gridMET and NLDAS precipitation datasets.

The last 30- and 60-day percentages of normal precipitation are also available, which show the difference of the last 30 or 60 days from the usual conditions for the same time period averaged from 1991–2020.

Precipitation data is updated daily, with a delay of 3 to 4 days. Learn more.

Temperature Conditions

The current temperature conditions show the average mean daily temperature for the last 7 days using the gridMET and PRISM temperature datasets. The last 7- and 30-day departures from normal temperature are also available, which show the difference of the last 7 or 30 days from the usual conditions for the same time period averaged from 1991–2020. 

Temperature data is updated daily, with a delay of 3 to 4 days. Learn more.
