(WTWO/WAWV) -- As the Wabash Valley prepares for the biggest snowfall it's seen in nearly six years, dispatchers say they're ready for calls they're about to receive. However, they do stress the importance of knowing when it's appropriate to call. According to Rob Gambill, director of the Clay County Emergency Management, they see a lot of accident related calls. "We have accidents that are caused by overconfidence of the vehicle, people have a lot of four wheel drive and all wheel drive vehicles. But, they have to understand they are not impervious to the elements or damages," Gambill said.
