Wind chill warning
From Wikipedia, the free encyclopedia
A Wind Chill Warning is issued by the National Weather Service of the United States when the wind chill is low enough that it becomes life threatening. The exact definition varies from state to state, and a warning is used to express more severe conditions than an advisory. If going outside, people should make sure to take extra precaution against hypothermia and frostbite by wearing multiple layers as well as a hat and gloves.[1]
