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 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 Long-Term MIDI approximates drought impacts from changes in precipitation and moisture over a long-term timeframe (up to 5 years), such as impacts to irrigated agriculture, groundwater, and reservoir levels. Long-term drought conditions can also increase wildfire intensity and severity.

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