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 Drought Monitor focuses on broad-scale conditions. Location conditions may vary.
This map is used by the U.S. Department of Agriculture to trigger disaster declarations and loan eligibility. Individual states and water supply planning may use additional information to inform their declarations and actions.

A 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.
Learn MorePeriods 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.
Learn MoreDrought 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.

Learn MoreDrought in the U.S.-Affiliated Pacific Islands
The U.S.-Affiliated Pacific Islands (USAPI) include three U.S. territories—American Samoa, Guam, and the Commonwealth of the Northern Mariana Islands—and three independent countries—the Federated States of Micronesia, the Republic of the Marshall Islands, and the Republic of Palau. The geology of the USAPI varies greatly—from volcanic high islands, to low coral atolls. Native ecosystems, traditional agricultural systems, hydrology, and interactions with the ocean are remarkably diverse. Droughts occur regularly and are often associated with El Niño events, which are part of a natural climate cycle in the Pacific Ocean.
The USAPI is vulnerable to the compound effects of climate change, including warming, changing drought conditions, and sea level rise, which contributes to saline contamination of freshwater supplies. Low atoll islands, where water supplies are limited to rainwater catchments, are particularly vulnerable to drought periods since water storage is often insufficient to sustain the local population. Drought in the USAPI can prompt Federal disaster declarations where residents are subject to mandatory water restrictions, and emergency deliveries of food, bottled water, and reverse osmosis pumps are required. Other impacts of drought include increased wildfire risk, negative public health and tourism impacts, loss of cultural practices, and reduced crop yields. Understanding the impacts of drought in the USAPI, summarizing the current state of the science, and improving resilience are important for successful adaptation and management.
NIDIS supports eight regional Drought Early Warning Systems (DEWS) throughout the United States. In addition, NIDIS supports states and territories outside these regions, like the USAPI, by delivering drought early warning information through Drought.gov; investing in drought research to address key scientific and societal needs; and supporting the development of new tools and products that serve the entire nation.
