Service Description:

The National Weather Service (NWS) River Forecast Centers (RFC) produce Hourly Quantitative Precipitation Estimates (QPE) for their individual RFC areas. These Hourly QPEs are used as input into their hydrologic models to produce NWS river forecasts and guidance products. The Hourly QPEs from each RFC are combined into a single mosaic to create a Hourly QPE product. The individual daily data products represents a hourly total. The service is updated hourly and provides information for the following time frames: Since 12Z, Last 1 Hour, Last 2 Hours, Last 3 Hours, Last 6 Hours, Last 12 Hours, Last Day (24 Hours), Last 2 Days, Last 3 Days, Last 4 Days, Last 5 Days, Last 7 Days, Last 10 Days, Last 14 Days, Last 30 Days, Last 60 Days, Last 90 Days and Last 120 Days. The data are on an approximate 4km x 4km grid cell scale. The RFCs produce the data using a multi-sensor approach utilizing NWS 88D radar estimates of precipitation, automated and manual precipitation gauges and satellite estimates of precipitation. These values are updated hourly.
