Current Conditons

A warm and dry week in the West and Plains led to more degradations. Areas of Extreme Drought (D3) expanded in the Northern Plains, and Exceptional Drought (D4) developed in Oregon for the first time since 2015. Conditions in California are also troublesome. The state has had back-to-back dry years, the wet season is over, and this water year is tied as the third driest on record. As of April 6, 2021, 37.6% of the U.S. and 45% 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 since 1980.

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

Temperature Conditions

The current temperature conditions show the average maximum daily temperature for the last 7 days using the gridMET and PRISM temperature datasets. The last 30- and 60-day departures from normal temperature are also available, which show the difference of the last 30 or 60 days from the usual conditions for the same time period averaged since 1980. 

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