Snow and ice caused 49 crashes in Bulloch County on Wednesday and early Thursday morning, and public safety officials warn drivers to continue with caution while frigid temperatures keep some areas frozen. Schools in Bulloch, Candler, Evans and Screven counties will remain closed today due to the remaining weather and travel conditions. “Areas around Stilson and Nevils still had some problems” Thursday, said Bulloch County Public Safety Director Ted Wynn.
