Update

Legend colors apply to both USGS gage and National Weather Service precipitation overlays (at full opacity).
* For precipitation values less than 0.01 inches, the USGS gage symbol is white and the NWS overlay is transparent.

Data: Hourly and Daily values are calculated from the last time a gage value was updated, which is not necessarily the time this web page was updated.

  • half shaded icon Half colored icons designate gage data that appears to be logging correctly but is over 1 hour and 15 minutes older than the NWISWeb time stamp at the top of the Rainfall page. The colored portion of the icon will represent the precipitation amount for that time interval.
  • full grey icon The "no data" icon is the result of an NWISWeb status code:
    • “ – – ” Parameter not determined, usually due to missing data.
    • “ Eqp ” Equipment malfunction.
    • “ Dis ” Data-collection discontinued.

USGS rain-gage data shown in the table are available at Water Data for the Nation : Current Iowa Precipitation

NWS Precipitation Image overlays are provided by the National Weather Service. The images are available at https://www.weather.gov/gis/cloudgiswebservices.
