  • NOAA MRMS
    A state of the art gridded analysis of RADAR data using observations and model data to help in the processing.
  • Oregon State PRISM
    The PRISM data is credit Oregon State University, created 4 Feb 2004. This information arrives with a few day lag. The plotted totals represent periods typical to COOP data reporting, so 12 UTC (7 AM local) each day.
  • Stage IV is a legacy NOAA precipitation product that gets quality controlled by the River Forecast Centers. This page presents 24 hours totals at 12 UTC each day.
  • Iowa Flood Center is an analysis produced by the U of Iowa IIHR.

Based on a sampling of recent timings for this application, plot generation time has averaged 10 seconds. Hold on for the plot is generating now!
