The National Weather Service says extreme cold will arrive Sunday night and peak on Monday before slowly moderating through Wednesday. Forecasters say temperatures may not rise to above zero from Sunday night through possiblyTuesday. Winds of between 15 and 30 mph will result in dangerously low wind chill values between 30 and 50 degrees below zero. Meteorologists say emperatures and wind chills this cold can easily result in exposed skin freezing within minutes and rapid onset of hypothermia. [Wind Chill Chart/National Weather Service Chicago]

•Stay indoors during the storm if possible.
•Avoid overexertion when shoveling snow. Overexertion can bring on a heart attack—a major cause of death in the winter.
•If you must go outside, wear several layers of loose-fitting, lightweight, warm clothing rather than one layer of heavy clothing. The outer garments should be tightly woven and water repellent.
•Wear mittens, which are warmer than gloves.
•Wear a hat. A hat will prevent loss of body heat.
•Cover your mouth with a scarf to protect your lungs.
•Watch for signs of frostbite. These include loss of feeling and white or pale appearance in extremities such as fingers, toes, ear lobes, and the tip of the nose. If symptoms are detected, get medical help immediately.
•Watch for signs of hypothermia. These include uncontrollable shivering, memory loss, disorientation, incoherence, slurred speech, drowsiness, and apparent exhaustion. If symptoms of hypothermia are detected, get the victim to a warm location, remove wet clothing, warm the center of the body first and give warm, non-alcoholic beverages if the victim is conscious. Get medical help as soon as possible.
•If the pipes freeze, remove any insulation or layers of newspapers and wrap pipes in rags. Completely open all faucets and pour hot water over the pipes, starting where they were most exposed to the cold (or where the cold was most likely to penetrate).
•Maintain ventilation when using kerosene heaters to avoid build-up of toxic fumes. Refuel kerosene heaters outside and keep them at least three feet from flammable objects.
•Conserve fuel, if necessary, by keeping your residence cooler than normal. Temporarily close off heat to some rooms.
•If you will be going away during cold weather, leave the heat on in your home, set to a temperature no lower than 55ºF.
