Instructions:

A Winter Storm Warning for snow means that heavy snowfall of 6 inches or more is expected. The rapid accumulation of snow will make travel extremely difficult, if not impossible. If travel is necessary, make sure to exercise extreme caution. Begin your travel with a full tank of gas, and carry a winter storm kit which includes a shovel, flashlight, cellphone, food and water, and blankets of extra warm clothing.

A Wind Chill Advisory means that very cold air and strong winds will combine to generate low wind chill values. This will result in frost bite and lead to hypothermia if precautions are not taken. If you must venture outdoors, make sure you wear a hat and gloves, making sure all exposed skin is covered.
