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).
The map is jointly produced by the National Oceanic and Atmospheric Administration,  U.S. Department of Agriculture, National Aeronautics and Space Administration, and National Drought Mitigation Center. Authors from these agencies rotate creating the map each week, using both physical indicators and  input from local observers.
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.

The Short-Term Multi-Indicator Drought Index (MIDI) estimates
current short-term drought conditions
across the U.S. by combining several indicators of drought into a single
computer-generated map.
Specifically, this map approximates drought conditions from changes in precipitation and moisture over the past 3 months. Short-term moisture deficits can impact non-irrigated agriculture, topsoil moisture, range and pasture conditions, and more.
Long-term droughts
(lasting months to years) can have different impacts.

drought index
combines multiple drought indicators (e.g., precipitation, temperature, soil moisture) to depict drought conditions. For some products, like the U.S. Drought Monitor, authors combine their analysis of drought indicators with input from local observers. Other drought indices, like the Standardized Precipitation Index (SPI), use an objective calculation to describe the severity, location, timing, and/or duration of drought.
Periods of drought can lead to inadequate
water supply
, threatening the health, safety, and welfare of communities. Streamflow, groundwater, reservoir, and snowpack data are key to monitoring and forecasting water supply.
Drought can reduce the water availability and water quality necessary for productive farms, ranches, and grazing lands, resulting in significant negative direct and indirect economic impacts to the agricultural sector. Monitoring
agricultural drought
typically focuses on examining levels of precipitation, evaporative demand, soil moisture, and surface/groundwater quantity and quality.

Drought in the Midwest
Drought and its impacts vary from region to region—due to differences in climate. Precipitation extremes in the Midwest have a major impact on the region’s resources, economic sectors, and residents. Over the last century, precipitation trends in the Midwest have been moving towards wetter conditions and fewer droughts than the region experienced in the early 20th century. However, the Midwest has still felt adverse impacts during recent droughts, particularly in 1988 and 2012. These adverse impacts include limited barge transportation on major rivers, decreased agricultural production, challenges for municipal water supply and quality, and reduced productivity for hydropower. In 2022 and 2023, drought conditions across portions of the Mississippi River Basin caused river levels to drastically lower, which had a significant impact on the transportation of goods along the river.
An added challenge in recent years has been the tendency to transition from drought to flood and back to drought within short time spans, sometimes within a matter of months, as well as
flash drought
, which is a drought that intensifies rapidly.
NOAA’s National Integrated Drought Information System (NIDIS) launched the Midwest
Drought Early Warning System
(DEWS) in response to the 2012 drought, which highlighted the need for additional drought early warning and preparedness in the region. The
Midwest DEWS
is a network of regional and national partners that share information and coordinate actions to help communities in the region cope with drought.

Periods of drought can lead to inadequate
water supply
, threatening the health, safety, and welfare of communities. Streamflow, groundwater, reservoir, and snowpack data are key to monitoring and forecasting water supply.
Drought can alter the ecological balance of natural systems and harm fish, wildlife, and plant species, as well as the benefits that these
ecosystems
provide to human communities. The environmental consequences of drought include losses in plant growth; increases in fire and insect outbreaks; altered rates of carbon, nutrient, and water cycling; and local species extinctions.
Because
energy
and water are so interdependent, the availability and predictability of water resources can directly affect energy systems. Energy professionals need information on current drought conditions and outlooks in order to make informed decisions on cooling, alternative water supplies, pricing, and infrastructure security.
During drought conditions that result in low water levels on rivers and other waterways, port and maritime
navigation and
transportation
operations may be limited due to a reduction in available routes and cargo-carrying capacity, resulting in increased costs. In addition, higher temperatures that often coexist with drought can impact roads, airport runways, and rail lines.

Soil moisture
plays an important role in drought and flood forecasting, agricultural monitoring, forest fire prediction, water supply management, and other natural resource activities. Soil moisture observations can forewarn of impending drought or flood conditions before other more standard indicators are triggered.
Flash drought
is the rapid onset or intensification of drought. Unlike slow-evolving drought, which is caused by a decline in precipitation, flash drought occurs when low precipitation is accompanied by abnormally high temperatures, high winds, and/or changes in radiation. These sometimes-rapid changes can quickly raise evapotranspiration rates and remove available water from the landscape.

Drought is defined as the lack of
precipitation
over an extended period of time, usually for a season or more, that results in a water shortage. Changes in precipitation can substantially disrupt crops and livestock, influence the frequency and intensity of severe weather events, and affect the quality and quantity of water available for municipal and industrial use.

Snow drought
is a period of abnormally low snowpack for the time of year. Snowpack typically acts as a natural reservoir, providing water throughout the drier summer months. Lack of snowpack storage, or a shift in timing of snowmelt, can be a challenge for drought planning.

Historical Drought Conditions in Indiana
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 Indiana 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.

, 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.

Dry Conditions
D4 (PMDI of -5.0 or less)
Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is
-5.0 or less
, indicating exceptional drought (D4) conditions.
D3 (PMDI of -4.9 to -4.0)
Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is
-4.9 to -4.0
, indicating extreme drought (D3) conditions.
D2 (PMDI of -3.9 to -3.0)
Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is
-3.9 to -3.0
, indicating severe drought (D2) conditions.
D1 (PMDI of -2.9 to -2.0)
Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is
-2.9 to -2.0
, indicating moderate drought (D1) conditions.
D0 (PMDI of -1.9 to -1.0)
Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is
-1.9 to -1.0
, indicating abnormally dry (D0) conditions.
Wet Conditions
W0 (PMDI of 1.0 to 1.9)
Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is
1.0 to 1.9
, indicating abnormally wet (W0) conditions.
W1 (PMDI of 2.0 to 2.9)
Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is
2.0 to 2.9
, indicating moderate wet (W1) conditions.
W2 (PMDI of 3.0 to 3.9)
Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is
3.0 to 3.9
, indicating severe wet (W2) conditions.
W3 (PMDI of 4.0 to 4.9)
Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is
4.0 to 4.9
, indicating extreme wet (W3) conditions.
W4 (PMDI of 5.0 or greater)
Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is
5.0 or greater
, indicating exceptional wet (W4) conditions.
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.
