  • Heavy Rain09/16/2009

    Hardin, Jefferson County

    1 death, 1 injured, $10K damage

    What happened

    A tree fell on a car that was traveling on Arkansas Highway 104. The car overturned into a water-filled ditch, killing the driver and injuring a passenger. Winds at the time of the accident were light. However, in the 24 hours prior to the accident, approximately 3 inches of rain had fallen, and according to the State Police report, rain was still falling at the time of the accident. It is believed that the heavy rains weakened the tree's roots and added extra weight to the foliage on the tree, causing it to fall.
