Event Synopsis

For the second time in a week, southeast Minnesota was hit by flooding rains. The weather pattern was eerily similar to the flooding event of June 7-8. This involved another strong area of low pressure over the upper midwest, and set the stage for severe storms, tornadoes, and flooding rains. Multiple tornadoes touched down in southern Minnesota, but damage was relatively light. The rains were the heaviest over Ortonville in Big Stone County and especially over south eastern Minnesota in the Austin area. The highest 24-hour total ending on the morning of June 12 was 4.25 inches at Lansing in Mower County about five miles north of Austin. Two day totals were between five and six inches over eastern Freeborn and western Mower County.

The heavy rains fell over already saturated ground in southeast Minnesota. By shortly after dark on June 11th, manhole covers were forced up due to the water pressure. Water was over many roads and cars were submerged in Austin. By the wee hours of the morning on June 12, Interstate 90 was closed in Austin due to floodwaters covering the interstate. Later that same day, residents of Austin were sandbagging to protect parts of the town due to rising creeks. One man died early on June 12th when he drove into deep water in a washed out spot on County Road 34 in Freeborn County. One person had to be rescued from a second car that plunged into the water.
