Winter storm impacts on air and road travel

With the snow approaching, travelers are being urged to use caution, especially when traveling on roads during the winter conditions.

Though folks usually think of jumper cables and first aid kits as vehicle emergency kits, AAA officials are encouraging folks to load up on other items to keep in your car.

"Make sure you have a portable collapsible snow shovel in case you need to dig out from somewhere," said Jana Tidwell, AAA Public Affairs. "That snow brush and ice scraper to clean off your car thoroughly before you start driving, plenty of washer fluid and deicer spray that salt and brine builds up quickly on our windshield, we a lot of that in the winter driving season rock salt, and kitty litter in case you need some additional traction under your tires."

Even though you might not end up using all these items for this storm, AAA says it’s important to always be prepared.
