U.S. Drought Monitor USDM 1-Week Change Short-Term MIDI Long-Term MIDI

The U.S. Drought Monitor depicts the location and intensity of drought across the country. The map uses 5 classifications: Abnormally Dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought (D1–D4).

This map is used by the U.S. Department of Agriculture to trigger some disaster declarations and loan eligibility. Individual states and water supply planning may use additional information to inform their declarations and actions. Learn more.

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.

Drought in the Northeast

Known best for its autumn foliage, thick forests, rocky soils, and abundant freshwater resources, the northeastern United States is characterized by a diverse climate that is not often associated with drought. However, in 2000, 2016, 2020, and 2022, New York and New England experienced historic drought conditions not seen since the 1960s.

The Northeast also frequently experiences “flash” droughts—the rapid onset of intense dry periods that can follow a period of normal to above-normal precipitation. While these flash droughts may last only 2–6 months, they can have profound impacts in the region, resulting in agricultural losses, shortages in public water supplies, and very low streamflows.

NOAA’s National Integrated Drought Information System (NIDIS) launched the Northeast Drought Early Warning System (DEWS) to improve drought early warning capacity and build long-term drought resilience throughout New England and New York. The Northeast DEWS is a network of regional and national partners that share information and coordinate actions to help communities in the region cope with drought.

Reach out to Sylvia Reeves, the Regional Drought Coordinator for this region, for more information, or sign up for the Northeast DEWS newsletter.

Historical Drought Conditions in Massachusetts

Drought is a normal climate pattern that has occurred in varying degrees of length, severity, and size throughout history. Below, you can look back at past drought conditions for Massachusetts according to 3 historical drought indices. The U.S. Drought Monitor is a weekly map that shows the location and intensity of drought across the country since 2000. The Standardized Precipitation Index (SPI) is a monthly depiction of drought based on precipitation (with data going back to 1895). And the paleoclimate data uses tree-ring reconstructions to estimate drought conditions before we had widespread instrumental records, going back to the year 0 for some parts of the U.S. View more historical conditions.

The U.S. Drought Monitor (2000–present) depicts the location and intensity of drought across the country. Every Thursday, authors from NOAA, USDA, and the National Drought Mitigation Center produce a new map based on their assessments of the best available data and input from local observers. The map uses five categories: Abnormally Dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought (D1–D4). Learn more.

W3	#0000FF	W3 (SPI of 1.6 to 1.9) The Standardized Precipitation Index (SPI) value for this location is between 1.6 to 1.9, indicating extreme wet (W3) conditions.
W4	#0000AA	W4 (SPI of 2.0 or more) The Standardized Precipitation Index (SPI) value for this location is 2.0 or greater, indicating exceptional wet (W4) conditions.

Drought results from an imbalance between water supply and water demand. The Standardized Precipitation Index (SPI) measures water supply, specifically precipitation. SPI captures how observed precipitation (rain, hail, snow) deviates from the climatological average over a given time period—in this case, over the 9 months leading up to the selected date. Red hues indicate drier conditions, while blue hues indicate wetter conditions. Data are available monthly from 1895–present. Learn more.

In paleoclimatology, proxy climate data (e.g., tree rings, ocean sediments) can allow us to reconstruct past climate conditions before we had widespread instrumental records. The Living Blended Drought Atlas, shown here, estimates average drought conditions each summer (June–August) as far back as the year 0 by combining tree-ring reconstructions and instrumental records. Red hues indicate drier conditions, while blue hues indicate wetter conditions.
