Minnesota braces for heavy rainfall and potential flooding
US · Published Sep 18, 2026
Minnesota is preparing for a significant weather event as a storm system is expected to bring widespread heavy rain from Friday morning into early Saturday.
The heaviest rainfall is forecasted for areas from the Twin Cities metro southward to the Minnesota–Iowa border, with totals ranging from 3 to 5 inches or more.

Impact & Risks

The primary concern is the potential for flooding, especially in areas prone to water accumulation. Localised flooding could occur in the southern Twin Cities metro area and regions extending south and east toward northeastern Iowa and southwestern Wisconsin. With rainfall totals possibly exceeding 5 inches in some locations, low-lying areas, streams, and rivers may experience elevated water levels. Residents in flood-prone zones are advised to monitor conditions closely, as repeated rounds of rain could exacerbate the situation.
