| Brief Description: A tornado touched down 2 miles south southwest of Niantic and travelled to the east northeast causing extensive damage. It moved into Old Harristown at 727 pm destroying 4 to 5 homes, extensively damaging the remainder of the homes, tore the roof off of the old grade school gymnasium, and destroyed a grain silo. It continued to the east northeast and moved into the westside of Decatur at the intersection of Wyckles and Center Roads after crossing I-72, destroying a church at that intersection, as well as a couple of homes. Then the tornado lifted to tree top level for a short distance till it reached Ravina Park Road. "F3" damage was seen, as the tornado demolished a house in a gully area, then continued to move to the east northeast down Ravina Park Road, causing "F2" damage. The width of the tornado was from 1 1/2 to 2 blocks wide in this area. It then crossed Oakland Avenue, destroying the Sims Lumber Company, and then it lifted to tree top level again. It dropped down again near the intersection of Bloomington Road and Pythan Avenue, causing minor damage before lifting again just east of Morgan Street. The tornado touched down once more at the intersection of Pershing and 27th, causing damage to the roofs of several buildings at a manufacturing plant and damaging the surrounding fences before lifting. Twenty-nine people were injured, two seriously and damage was estimated around $9 million. | |||||||||||
