Wind chill warning
A wind chill warning is issued by Environment Canada or the National Weather Service of the United States when the wind chill is low enough that it becomes life-threatening.
In the United States the exact definition varies from state to state or from National Weather Service county warning areas to another, 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.
In the event that extreme wind chills are expected to quickly lead to frostbite or death, enhanced wording with the words particularly dangerous situation may be added to the text; this is rarely issued. The National Weather Service in Twin Cities/Chanhassen was the first office to do this on Sunday, January 5, 2014.〔(【引用サイトリンク】url=http://mesonet.agron.iastate.edu/vtec/#2014-O-NEW-KMPX-WC-W-0001/USCOMP-N0Q-201401050000 )〕
As of April 8 2014, Environment Canada replaced the Wind Chill Warning with an Extreme Cold Warning. The warning is still issued based on a region's normal climate. In the older system a wind chill warning for Southern Ontario and Atlantic Canada was issued when the wind chill dropped to -35. This meant that if the temperature was with no wind a warning was not issued. Under the new system the extreme cold warning is issued based on either the temperature or the wind chill being a certain value for at least two hours. The values range from in the south to in parts of the Arctic.〔(Extreme Cold Warning )〕
