1983: Heavy rainfall up to four and a half inches fell in the town of Mahto, Corson County, flooding basements. Hail, up to three inches in diameter, caused heavy damage to roofs and broke numerous windows.

1998: Very heavy rainfall of 3 to over 6 inches fell across far eastern Corson, most of Campbell and Walworth counties during the evening hours of the 26th. The heavy rain caused flooding on many roads along with some highways through the night and into the morning hours on the 27th. Near Selby, high winds, heavy rain, and some hail caused damage to sunflowers and moved a barn three feet off the foundation. In Selby, wind driven rain pushed water through some ceilings and into basements. An old barn near Glenham was also blown down by the strong winds. Some rainfall amounts include, 3.50 inches at Herried, 3.80 inches at Java, 4.20 inches at Selby, 4.50 inches 3N of Selby and just southeast of Mclaughlin, 5 inches at Glenham, 5.75 inches 8N of Mobridge, and 6.35 inches 1.5 miles southeast of Glenham.

1883: The Krakatoa Volcano exploded in the East Indies. The explosion was heard more than 2500 miles away, and every barograph around the world recorded the passage of the air wave (sometimes up to seven times). Giant waves 125 feet high and traveling 300 mph devastated everything in their path, hurling ashore coral blocks weighing up to 900 tons, and killing more than 36,000 people. Winds carried volcanic ash around the globe in 13 days, producing blue and green suns in the tropics, and then vivid red sunsets in higher latitudes. The temperature of the earth lowered one degree for the next 2 years, eventually recovering to normal almost 5 years later.

1908: South Carolina's greatest flood ever caused flooding statewide. Every river in the state rose above flood stage, many as high as 22 feet above flood.
