• Ice Storm02/01/2011

  Johnson

  1 death, $75K damage

  What happened

  Freezing rain and heavy sleet blanketed the county followed by less than an inch accumulation of snow. The sleet and ice made travel treacherous around the county. Most of the vehicle incidents reported were due to stuck vehicles or vehicles that had slid off the roadway. The prolonged cold that settled in after the ice storm kept the roads treacherous for the next four days and many schools and businesses were closed for just as long. The icy roads resulted in a fatality on the night of the 3rd. A man was killed when his truck slid into a ditch and hit a tree on CR 915A near Joshua.
