As the wind increases, heat is carried away from the body at an accelerated rate, driving down the skin temperature and eventually the internal body temperature. Therefore, the wind makes it feel much colder. If the temperature is 0 degrees Fahrenheit and the wind is blowing at 15 mph, the wind chill is -19 degrees Fahrenheit. At this wind chill temperature, exposed skin can freeze in 30 minutes.

    This Wind Chill Temperature Index was issued by the National Weather Service and the Meteorological Services of Canada beginning with the 2001-2002 winter season and is the first significant change to the 1945 Siple and Passel Index.
