This page shows gridded precipitation products for the previous 1-hour, 6-hours, 24-hours, 7-days, and current water year, as well as rain gauge observations for the previous 24-hours from the Community Collaborative Rain, Hail & Snow Network (CoCoRaHS) and water-year-to-date rain gauge observations throughout California. Gridded precipitation data are the National Stage IV Quantitative Precipitation Estimate (QPE) Product, provided by the NOAA/NCEP/EMC. Normal precipitation data are the CPC US Unified Precipitation product, provided by the NOAA/OAR/ESRL PSD, Boulder, Colorado.
