Rainfall frequency maps

Latest revision as of 13:06, 26 January 2023

Information: Precipitation frequency information (Atlas 14) has been updated by the National Oceanic and Atmospheric Administration (NOAA). We recommend using Atlas 14.

NOAA's Atlas 14, Volume 8 precipitation frequency information can be found on NOAA's precipitation frequency data server. Rainfall frequency maps from Technical Paper 40 have been moved to this page. Although we recommend going to the NOAA site for rainfall information, we've provided rainfall frequency plots for several locations in Minnesota. To see a comparison of Atlas 14 and TP-40, link here. For additional information on Atlas 14 and comparisons with TP-40, see the following pages.

To see information on frequency-volume relationships, see this page or Issue Paper B.

Minneapolis-St. Paul International Airport

Rochester International Airport

Marshall
