Episode Narrative A complex of thunderstorms that developed across southeast North Dakota, moved into west central Minnesota during the early morning hours of Friday, July 15th.

Several waves of thunderstorms moved across west central and central Minnesota during the morning, then mainly across east central and south central Minnesota during the afternoon. Due to the tropical type air mass in place, rainfall rates were extremely high, with many areas averaging two inches or more per hour. Although some large hail was reported, most of the thunderstorm hazard was associated with flash flooding with some minor wind damage.

The worse flooding occurred across Douglas County and between Alexandria and Sauk Centre. Northeast Meeker County also received excessive rainfall that caused several roads to close during the height of the storm. Portions of south central Minnesota during the afternoon also received excessive rainfall and caused flooding in a local park.
Event Narrative Two waves of very heavy rainfall occurred between 6 and 8 am, and started causing significant flooding around the communities of Carlos, Alexandria, and Osakis, Minnesota. Nearly 7 inches of rain fell in a short period of time near Osakis, where local officials reported several inches of water over the roadways. A few areas received basement flooding and a local high school reported flooding in classrooms.
