Frostbite and hypothermia are serious risks in weather like today. In frostbite, freezing occurs in the deep layers of skin and tissue. Skin becomes pale, and waxy-white, hard and numb. Frostbite normally affects the fingers, hands, toes, feet, ears and nose. Hypothermia is more serious and is a medical emergency. You can spot signs of hypothermia if body temperature drops to or below 95°F causing fatigue or drowsiness; uncontrolled shivering; cool bluish skin; slurred speech.
