Service Description:

Map Name: River Forecast Centers Daily Quantative Precipitation Estimates (QPE)


All Layers and Tables

Layers: Description: The 13 National Weather Service (NWS) River Forecast Centers (RFC) produce Quantitative Precipitation Estimates (QPE) for their individual RFC areas. These QPEs are used as input into their hydrologic models to produce NWS river forecasts and guidance products. The QPEs from each RFC are combined into a single mosaic to create a QPE product that covers the lower 48 states, Alaska and Puerto Rico. The individual daily data products represent a 24 hour total ending at 12UTC on the indicated date. These 24-hour data are then summed together to produce multi-day precipitation totals. Normal precipitation data are also produced for the same daily and multi-day summations using data from the PRISM Climate Group. Percent of normal and departure from normal comparisons are also available by comparing the QPE data with the PRISM normal data. 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. The daily data are updated several times between 12UTC and 21UTC each day and may be adjusted several times as more data becomes available.
