A strong upper level disturbance produced heavy rain around Lead, Deadwood, and Central City. Four to five inches of rain fell in two hours, causing widespread street flooding in Lead and Deadwood. Six to 12 inches of water flowing down Main and Sherman Streets in Deadwood flooded cars, basements, and businesses. The electrical system of the Broadway Parking Ramp elevator was destroyed. Hail broke windows of a basement pub, which then filled with water about three and a half feet deep.
