Information: Precipitation frequency information is being updated by the National Oceanograpic and Atmospheris Administration (NOAA). The Minnesota Stormwater Manual will eventually be updated using Atlas 14 information.
Information: This page provides the following information on rainfall frequency distributions for Minnesota:
- Rainfall frequency curves for the 1, 2, 5, 10, 25, 50, and 100 year 24-hour rainfall events for Minnesota. The source of the data is Technical Paper 40 (National Oceanic and Atmospheric Administration)
- Rainfall frequency and volume percentiles as a function of precipitation depth for ten locations in Minnesota. Rainfall frequency specifies the number of 24-hour rain events, expressed as a percent of all events, that are less than a certain depth. Volume represents the total annual volume of rain that is associated with a particular rain depth. For example, 88 percent of rain events in Cloquet are 1 inch or less, while rain events of one inch or less account for 60 percent of the annual volume.
