Drought Prediction and Monitoring Tools

Mountain Range Drought Monitor

University of Nebraska - Lincoln.

"A synthesis of multiple indices, outlooks and news accounts, representing a consensus of federal and academic scientists" from USDA, the Department of Commerce, the Department of the Interior and the National Drought Mitigation Center (NDMC).


Evaporative Stress Index

USDA. Agricultural Research Service.

The Evaporative Stress Index (ESI) describes temporal anomalies in evapotranspiration (ET), highlighting areas with anomalously high or low rates of water use across the land surface.


Planted field. Weekly Weather and Crop Bulletin

USDA. Joint Agricultural Weather Facility.

Contains "weekly national agricultural weather summaries, including the weather's effect on crops; summaries and farm progress for 44 states and the New England area. This report includes any corrections to the Crop Progress data released the previous day."


National Integrated Drought Information System (NIDIS)

DOC. National Oceanic and Atmospheric Administration.

Ensures "collaboration between different government agencies on drought-related issues" and gives information on current drought conditions, forecasting, impacts and more.


Crop Weather

USDA. Risk Management Agency.

A clearinghouse of weather information for agriculture.


Stream Water Watch

DOI. United States Geological Survey.

A compilation of ''maps and graphs of current water resources conditions'' including daily streamflow condition maps. Daily streamflow condition maps depict streamflow conditions as measured at United States Geological Survey (USGS) gaging stations. Please note that "the real-time data used to produce the maps are provisional and have not been reviewed or edited. The data may be subject to significant change."


North American Drought Variability

DOC. NOAA. National Environmental Satellite, Data, and Information Service.

Focuses its work toward "drought variability for the last ca. 100 years based on instrumental data, and on the last several centuries and millennia based on paleoclimatic proxy data." Related information can be found through NOAA's Paleoclimate Drought Resources page.


Advanced Hydrologic Prediction Service

DOC. NOAA. National Weather Service.

"Provides new forecast products (including visual displays) depicting the magnitude and uncertainty of occurrence for hydrologic events from hours to days to weeks."
