For our routine river forecasts, only 12 hours of QPF is normally used. Under certain conditions and based on specific requests by our users, we will utilize 24 hours of QPF in them. A full 72 hours of QPF is used as input to our river models to produce local Significant River Flood Outlooks and National Significant River Flood Outlooks. Therefore, the daily Significant River Flood Outlook does not account for a full 5 days of QPF covering the LMRFC river forecast area.   5-Day QPF for the United States can be found at http://www.hpc.ncep.noaa.gov/qpf/day1-5.shtml.
