According to the National Weather Service, a winter storm warning for snow and sleet 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.
