MINNEAPOLIMEDIA NEWS | Torrential Rain Triggers Flooding, Mudslides and Road Closures Across Southern Minnesota

NEW RICHLAND, MN (September 20, 2026). Communities across southern and southeastern Minnesota are assessing flood damage after torrential rainfall inundated streets, damaged property and sent mudslides across state highways.

More than six inches of rain fell in portions of the region from Friday night into Saturday morning, according to weather reports. New Richland and Spring Valley were among the communities reporting significant flooding.

In New Richland, floodwater covered streets and entered some properties as drainage systems struggled to handle the rapid accumulation. Residents and local officials worked to protect homes and move vehicles from rising water.

Flooding also affected roads throughout the region. Motorists encountered standing water, closures and debris, while mudslides blocked portions of some state highways.

The Minnesota Department of Transportation and local public-safety agencies urged drivers not to enter flooded roadways. Water can conceal damaged pavement, washed-out shoulders and strong currents capable of moving a vehicle.

River levels were also rising as runoff moved through local watersheds. Additional rain in neighboring parts of Iowa and Wisconsin increased concern about continued pressure on waterways and low-lying areas.

The immediate emergency may recede before the full cost becomes clear. Flooding can damage roads, culverts, bridges, basements, crops and municipal infrastructure. Local governments may need several days to document damage and determine whether state or federal assistance thresholds have been met.

Residents returning to flooded buildings should avoid standing water near electrical systems and should document property damage before beginning cleanup when it is safe to do so. Private well owners may also need to test water if floodwater reached a wellhead.

The event underscores the danger of highly concentrated rainfall. A community does not need to be next to a major river to experience damaging floods when several inches fall faster than storm sewers, ditches and small waterways can carry it away.

Forecasts and road conditions may continue changing. Travelers should consult the National Weather Service, Minnesota 511 and local emergency-management notices before entering the affected area.
