Black Sunday: April 30, 1967

Iowa Time Machine ⏰: On April 30, 1967, a major tornado outbreak known regionally as “Black Sunday” struck parts of downstate Minnesota and northern Iowa, with multiple tornadoes impacting towns including Clear Lake and Manly. The outbreak produced 21 tornadoes in the broader region, causing 13 fatalities and about 80 injuries overall.

In the 1960s, tornado forecasting was far less advanced than it is today, and rural communities often depended on warning signs, radio reports, and plain luck as storms built across the Plains and Upper Midwest. The outbreak struck a landscape where farming, small towns, and open countryside left people especially exposed to fast-moving tornadoes.

Just to the northeast of Clear Lake, a tornado caused major damage throughout rural Worth County. Newspapers reported at least four dozen farms directly impacted by the storm, with the majority seeing homes entirely destroyed. A tornado threatened Many, touching down just north of Highway 9 and to the east of town.

Just north of the border, a tornado passed through Albert Lea. Waseca also experienced tragic fallout from the storm as it ripped north. The day stands as a reminder how ordinary spring weather can quickly become a regional catastrophe. #Iowa #OTD #History #Tornado #Weather
