The NWS Wind Chill Temperature Index uses advances in science, technology and computer modeling to provide an accurate, understandable and useful formula for calculating the dangers from winter winds and freezing temperatures.
Wind chill temperature is only defined for temperatures at or below 50˚F and wind speeds above 3 mph. Bright sunshine may increase the wind chill temperature by 10˚F to 18˚F.
The wind chill temperature is how cold people and animals feel when outside. Wind chill is based on the rate of heat loss from exposed skin caused by wind and cold. As the wind increases, it draws heat from the body, driving down skin temperature and eventually the internal body temperature. Therefore, the wind makes it FEEL much colder. If the temperature is 0˚F and the wind is blowing at 15 mph, the wind chill is -19˚F. At this wind chill temperature, exposed skin can freeze in 30 minutes.
You have frostbite when your body tissue freezes. The most susceptible parts of the body are fingers, toes, ear lobes, or the tip of the nose. Symptoms include a loss of feeling in the extremity and a white or pale appearance. Get medical attention immediately for frostbite. The area should be slowly rewarmed using warm, not hot water.
