The start of the Great Tri State Tornado that killed 695 people, injured 2027, and caused $16,500,000 in property damage developed over Reynolds County and quickly moved into Iron County.  The funnel was very wide, a double tornado, or accompanied by downbursts as it enveloped Annapolis and a mining town called "Leadanna" 2 miles S of Annapolis.  Two people were killed and 75  more were injured in that area.  Losses in both towns totaled about $500,000.  It then quickly moved NE through Madison County before moving through parts of southern Illinois and southwest Indiana.  While F2 was probably the maximum damage caused in Iron County, this tornado did cause F5 damage later in its path.  It is widely accepted that this was likely a series of tornadoes instead of one long tracked tornado.

A tornado touched down in the Clayton Creek area, 15 miles SE of Viburnum.  The tornado first touched down near the intersection of Highways 49 and 32 and produced intermittent damage to just east of Highway DD, about 5 miles NE of the initial touchdown.  A family sitting in a brick frame house was aware of a severe thunderstorm warning.  They heard and saw the tornado coming, and were able to get to the basement before the storm hit.  The house was severely damaged, but no one was injured.  A stock trailer was on the S side of a station wagon before the storm.  The trailer and station wagon were removed from their location and carried to a second location a short distance away.  The stock trailer was then resting on the other side of the station wagon.  Several barns were destroyed, as well as several old houses.
