Meteorological synopsis

Very warm, humid, summertime air had pushed into central on southern Minnesota on August 6, 1969. Minneapolis saw a high temperature of 93 °F (34 °C) with dew points near 70 °F (21 °C). Meanwhile, strong upper-level winds over northern Minnesota and an approaching cold front from the west added the needed ingredient for the strong storms.

Outbreak description

Thirteen tornadoes touched down that day, killing 15 and injuring 109. The first tornado of the day, an F0, touched down at 12:15 pm CDT in Beltrami County. The main tornado event started about three hours later in Cass County when an F3 tornado touched down southwest of Backus, injuring four people.

The most damaging tornado of the outbreak touched down at 3:48 pm in Crow Wing County. It achieved F4 strength, traveling 38 miles (61 km) through Crow Wing, Cass and Aitkin counties. The area around Outing was especially hard hit by this tornado, where 11 deaths and 40 injuries occurred on the shores of Roosevelt Lake.

Several more strong tornadoes touched down over the next two hours, killing one person near Jacobson and two people near Two Harbors. Damage and casualties were limited however because most of the twisters struck rural areas.
