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

Forecasts & Outlooks
NWS Forecasts

View current conditions and short- to medium-range (1-7 days) forecasts for precipitation, temperature, wind, and clouds. These forecasts often identify potential hazards such as heavy precipitation three or more days in advance.

Precipitation Forecasts

View forecasts of cumulative precipitation for periods from 6 hours to 7 days into the future. Monitoring this site can alert decision makers of the potential for wet weather and/or flooding.

The National Water Model (NWM) forecasts streamflow over the entire continental United States. It is a hydrologic model that predicts the flow in over 2.7 million stream reaches of the National Hydrography Dataset Plus, mathematically modeling physical processes such as snowmelt, infiltration, and the movement of water through soil layers in order to determine how much of the NWS precipitation forecast becomes runoff, then routing that runoff through the river network.

Hazard Outlooks

This site shows the chances for Severe Weather and Fire Weather over the next 8 days. Browse a range of information on severe weather events including tornadoes, thunderstorms, winds, and hail.

Drought Outlook

Maps show how conditions related to drought are likely to change over the valid period. Outlooks indicate areas where drought is likely to develop, persist (or worsen), improve, or end.

Hazards Outlook

Hazard outlooks for the next 3-7 and 8-14 days. Get advance notice of the potential for flooding, severe storms, extreme temperatures, drought, and risk of wildfires.

Monthly Precip Outlook

View monthly maps showing the probability for precipitation ranking in the top, middle, or bottom third of historical observations. Outlooks that favor drier or wetter periods can raise awareness of the potential for changing conditions.

Tropical Weather Outlook

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.

Probability of Exceeding a Precipitation Threshold

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.

Percent Increase in Risk of Extremes due to ENSO

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.

Weather Model Analysis and Guidance

This site offers maps, animations, and plots from weather observations and prediction models. The graphic products for Model Guidance, Observations and Analyses, and Tropical Guidance can be useful for monitoring development of potential storms.

Current Observations
Daily Streamflow Conditions

Colors indicate current streamflow. Click any region on the site, and then click individual stations to access graphs or raw data on streamflow and precipitation. This display can help water managers judge short-term future supply.

River Observation Locations

View current and predicted flood status at more than 7,500 gauges in the United States. Click to zoom in on a region, and then roll your cursor over gauge locations to view hydrographs of recent and forecast discharge levels.

View tool demo >

River Forecast Centers

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.

Current Drought

This weekly map—updated every Thursday—shows experts' assessments of regional conditions related to dryness and drought. The maps focus on broad-scale conditions, so local conditions may vary.

View tool demo >

Soil Moisture

Access maps that show estimates of surface soil moisture. View Total, Anomaly, Percentile, or Change in soil moisture over the last month or season. Monitoring this site can help decision makers judge field conditions and the potential for drought development.

Watershed Assessment, Tracking, & Environmental Results System

WATERS (Watershed Assessment, Tracking, & Environmental Results System) provides comprehensive information about the quality of surface water across the nation.

National Snow Analyses

Maps and animations show snow analyses for 18 regions of the contiguous United States. For specific weather stations, graphs show observed and modeled snowpack to estimate the amount of water stored as snow.

View tool demo >

Daily maps show the extent of snow cover (and ice) over the contiguous United States, Alaska, or the whole Northern Hemisphere. Images are embedded in an animation tool that enables users to identify daily changes and seasonal trends.

One-day snowfall

This daily map shows snowfall accumulation reported at individual stations across the contiguous United States.

Historical Observations
Daily Summary Observations

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.

Daily Normals by Weather Station

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.

View tool demo »

Hourly Precipitation

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.

Extreme Events

Access records of heat waves, droughts, tornadoes, and hurricanes. Explore 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.

Map Layers from Data.gov
Rivers and streams

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.

Flood Hazard Zones

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.

Impervious Surfaces (2011)

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.

Land cover (2011)

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.

Population Density (2000)

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.

Social Vulnerability Index

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.
