Those who travel even during the worst of times are advised to carry a winter storm supply kit in their vehicle. Assemble a separate disaster supplies kit for the trunk of each car used by members of your family that includes:
Blankets or sleeping bag
Extra sets of dry clothing
A windshield scraper
A shovel
A container of sand
Tire chains
Battery booster (jumper) cables
A tow chain or rope
First aid kit
Flashlight or emergency light with extra batteries
Transistor radio with extra batteries
A brightly colored cloth
Candles
A high calorie, nonperishable food
Another item that might make the difference is a cell phone. If you are stranded in your car during a blizzard, make a call and wait for help to arrive. Do not try to walk to safety.
