Water Resources Dashboard
Water resource managers and urban planners can use this dashboard to access maps and data that help them monitor the potential for extreme precipitation and drought in their regions. The Acknowledgments page lists the individuals who helped select our initial offerings.
Note that this is a dynamic page: the scope and content of dashboard entries are driven by input from users. We welcome your suggestions and additions to improve its usefulness. Please email us with your suggestions.
The National Hurricane Center monitors marine weather and indicates the chance that disturbances will develop into tropical storms. For storms that do develop, the site shows predicted paths and storm status. Monitor this site to be aware of the potential for tropical storms and/or hurricanes.
Check the probability that cumulative rainfall will exceed user-defined thresholds within the next three days during 6- to 24-hour intervals. This forecast can serve as an early alert for potential flooding.
This interactive map shows regions where the risk of having a seasonal extreme in temperature or precipitation is elevated during El Niño or La Niña conditions. Decision makers can identify areas that have an increased or decreased risk of extreme warm/cold (or dry/wet) seasons, and plan accordingly.
Dots on this map indicate current streamflow: a quick look can show if water levels in your region are high, normal, or low. Click any region on the site, and then select stations to access graphs or raw data on streamflow and precipitation. Monitoring this site can help water managers judge short-term future supply.
View observed flow conditions across 13 regions of the contiguous United States. For each gauge location, access hydrographs showing observed and predicted water levels that account for upcoming weather and snowmelt.
WATERS (Watershed Assessment, Tracking, & Environmental Results System) provides comprehensive information about the quality of surface water across the nation.
Access summary observations from more than 90,000 land-based stations around the world. Data may include precipitation, maximum and minimum temperature, temperature at the time of observation, and/or snow depth. A How-to Guide provides assistance with selecting stations of interest in the map interface.
Use this GIS interface to select stations for which you want to view daily normals. Climate Normals are the latest three-decade averages of climatological variables, including temperature and precipitation. Hourly, monthly, and annual normals are also available.
Use this GIS interface to select from more than 5000 stations that indicate maximum observed rates of rainfall. You can consult these records to see historical extremes for locations of interest.
Access various records of extreme events such as heat waves, droughts, tornadoes, and hurricanes. This site provides a range of tools for exploring weather records tied or broken for each day of the year, disasters that cost a billion dollars or more, and special reports and indices that characterize extreme events.
This tile cache base map combines the National Hydrography Dataset (NHD) and the Watershed Boundary Dataset (WBD). Use the data as an overlay in your own analysis software, or access it through the Climate Explorer.
Local areas that carry an official designation of risk with respect to flooding show up on this map. The map highlights land that FEMA has judged to have a chance of flooding or lie within a regulatory floodway. Checking which areas of a community carry these designations is an important part of assessing vulnerability. View the layer in your own analysis software or the Climate Explorer.
Parking lots, rooftops, and roads block water from soaking into the ground. These impervious surfaces can increase stormwater runoff, promote flooding, and contaminate surface waters. Explore this tile cache base map of impervious surfaces in your own analysis software, or view it in the Climate Explorer.
This satellite-derived map can help viewers figure out what is on the ground across a region. Colors show 21 different categories of natural vegetation, crops, and development. Explore the layer in your own analysis software, or view it in the Climate Explorer.
View estimates of the number of humans living within each square kilometer of the planet during the year 2000. Users can compare the locations of urban and rural populations and identify clusters of residents in rural areas. Download the layer and view it in your own analysis software, or view it in the Climate Explorer.
This map shows communities’ vulnerability to environmental hazards based on demographic measures drawn mostly from the 2010 Census. Local officials can use the information to identify communities that may need support in preparing for hazards or recovering from disasters.
