What the National Weather Service wrote

A man was killed when he attempted to cross flood waters with two others in his vehicle. The car was washed away on County Road 6 near Pine Creek. His two female companions were rescued but the victim's legs were pinned under a part of the car and rescue workers could not save him. Several rescue workers also became caught in flood waters which swamped at least two rescue boats. This all occurred during the early morning hours of Sunday, August 19th in darkness.

Highway 26 from La Crescent to the Iowa border, Highway 16 from La Crescent to Hokah, and Highway 61 north of La Crescent were all closed by flood waters and damage.

The wider storm

A warm front lifting northward into Iowa triggered round after round of thunderstorms with excessive rainfall across southeast Minnesota during the evening and overnight hours of August 18-19. This was after rain had fallen earlier in the day. Total rainfall amounts of 10 to 15 inches were common, which produced widespread and significant flash flooding. An official rainfall total of 15.1 inches near Hokah (Houston County) established an all-time 24 hour rainfall record for the state of Minnesota. Other rainfall totals, which were unofficial readings, included 17.00 and 14.00 inches respectively in Witoka and Utica (Winona County). Numerous roads and bridges were washed out, houses collapsed due to mudslides and hundreds of homes had flooded basements. Law enforcement and fire department officials reported rescuing people from their vehicles, as well as from house tops. There were seven fatalities reported, five in Winona County and two in Houston County. Damage attributed to the heavy rainfall and subsequent flooding was estimated to be in the millions of dollars. Fillmore, Houston, Olmsted, Wabasha and Winona counties were declared federal disaster areas.

Began near La Crescent (43.8300, -91.3201).
