Drought Indicators

Indicators are variables used to describe drought conditions (e.g., precipitation, temperature, streamflow, groundwater and reservoir levels, soil moisture, and snowpack). In order to get a complete picture of drought conditions, several drought indicators should be examined.

The Multi-Indicator Drought Index (MIDI) looks at current drought conditions across the U.S. by integrating several key drought indices on precipitation and moisture into one objective, computer-generated map. 

The Short-Term MIDI is released every 5 days and approximates drought impacts from changes in precipitation and moisture over a short-term timeframe (looking back up to 90 days), such as impacts to non-irrigated agriculture, topsoil moisture, and range and pasture conditions. Long-term droughts (lasting months to years) can have different impacts.

This experimental map is based on methodology from the NOAA National Weather Service’s Climate Prediction Center. Learn how this map is made.

The Evaporative Demand Drought Index (EDDI) is an experimental drought monitoring and early warning guidance tool. 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. This experimental subseasonal EDDI forecast shows projected evaporative demand for the next 2 weeks and 4 weeks from the CFS-gridMET dataset at 4-km gridded resolution. Learn more.

NOAA's Climate Prediction Center issues Monthly and Seasonal Drought Outlooks each month.

The Monthly Drought Outlook predicts whether drought will emerge, stay the same, improve, or be removed in the next month. Learn more.

The Seasonal Drought Outlook predicts whether drought will emerge, stay the same, improve, or be removed in the next three months. Learn more.

Historical Conditions for Clackamas County

The U.S. Drought Monitor (USDM) is a national map released every Thursday, showing parts of the U.S. that are in drought. The USDM relies on drought experts to synthesize the best available data and work with local observers to interpret the information. The USDM also incorporates ground truthing and information about how drought is affecting people, via a network of more than 450 observers across the country, including state climatologists, National Weather Service staff, Extension agents, and hydrologists. Learn more.
