Flash Flood in CASS, NORTH DAKOTA

Three to four inches of rain in three hours produced widespread street flooding, flooding of underpasses, storm sewer backup, and basement flooding across the Fargo area. Water was reported to be up to the bases of fire hydrants near 45th Street and 12th Avenue North, making the roads impassable. River levels in town were already above minor flood stage due to previous heavy rainfall in the area, which meant that storm sewer flap gates were closed and pumping stations were likely overwhelmed by the high local runoff rates.
