The windy and snowy weather conditions caused havoc on Central Ohio roadways this morning.Columbus police and Franklin County Sheriff's deputies responded to more than a dozen accidents with injuries, and roadways like I-71 in Columbus and U.S. route 33 in Hocking County were closed because of accidents on slick pavement. It's all due to a nasty weather system that moved in from the West. Metorologist Rob Carolan says the system is expected to move East by daybreak Saturday, but will leave its mark today.
