| Brief Description: An eventual f4 tornado began its destructive path around 6 miles southwest of Coleridge. The tornado moved northeast and crossed the northern sections of the city uprooting trees, downing power lines and destroying a couple of grain bins. A construction business in a garage was also destroyed. The tornado then continued northeast of town hitting a large hog farm. At this farm a 70-year-old man was killed while in a storage shed when a tractor that was flipped by the winds crushed him. Many livestock were also killed by debris or flung through the air by the deadly winds. In one case cattle were carried over a mile then left dead in a pile. The tornado then widened to around 3/4 of a mile, reaching its maximum intensity. Numerous vehicles were tossed at this location and a complete farmstead was flattened. Trees were also stripped and debarked. The tornado remained around 3/4 of a mile wide for a few more miles before turning slightly to the southeast and diminishing, but not before hitting 2 more farmsteads and moving one house off of its foundation. In total, 11 homes received substantial damage and between 100 and 200 utility poles were downed. M70EQ | |||||||||||
