Instructions:

An Extreme Cold Warning means that dangerously low temperatures are expected for a prolonged period of time. Frostbite and hypothermia are likely if exposed to these temperatures. Wear protective clothing such as a hat, face mask, and heavy gloves or mittens if you have plans to be outdoors. To prevent freezing and possible bursting of outdoor water pipes they should be wrapped, drained, or allowed to drip slowly. Those that have in-ground sprinkler systems should drain them and cover above-ground pipes to protect them from freezing. A Dense Fog Advisory means visibilities will frequently be reduced to one quarter mile or less. If driving, slow down, use your low beams, and leave plenty of distance ahead of you.
