Water Supply Forecasts
The Water Supply Forecasts page contains reports, maps, and graphs to assist in forecasting and managing the
water supply for the western United States.
Snow Telemetry (SNOTEL) and Snow Courses
The SNOTEL and Snow Course Data and Products page provides access to data and reports derived from snow survey sites
and snow courses located in the western United States and Canada. Here you'll find state- and site-specific data, maps, and graphs showing snow water equivalent (SWE), snow depth,
precipitation, temperature, and other climatic elements in hourly, daily, monthly,
and yearly increments. These products are used for forecasting and
management of water supplies.
Soil Climate Analysis Network (SCAN)
The Soil Climate Analysis Network Data and Products page provides access to data and reports derived from SCAN sites located across the United States, Puerto Rico, and the Virgin Islands. SCAN sites are automated, remote sites which
collect soil moisture and soil temperature data along with precipitation, wind,
and solar radiation data. These data are used for the management
and prediction of climatic issues affecting our natural resources.
The Climate Support products include Agricultural Applied Climate Information System (AgACIS) data for wetlands determination,
temperature and precipitation summaries, frost-free days, and growing seasons.
Access to PRISM Climate Group data is provided, along with links to soil moisture and wind rose resources.
The National Water and Climate Center supports an Interactive Map which provides easy navigation to NRCS and other network monitoring stations. The map displays current and historical conditions for SWE, snow depth, precipitation, streamflow, and reservoir storage.
In addition, the Map Products page offers a suite of
maps displaying variables such as SWE, snow depth, snow
density, precipitation, and temperature. Maps are generated at a variety of
scales for the western United States using SNOTEL, snow course, and ACIS data.
