Wind Chill Advisory, Watch, and Warning Defined

December 3, 2007

By WeatherBug Meteorologist, Dustin Devine

Exclusive WeatherBug Video on Wind Chill

A Wind Chill Advisory is issued when potentially dangerous wind chill readings lower than minus 25 degrees are expected.

A Wind Chill Watch is issued when conditions are favorable for dangerous wind chills lower than minus 35 degrees within the next 12 to 48 hours.

A Wind Chill Warning is issued when life-threatening wind chill readings lower than minus 35 degrees are possible.

Exposure to this combination of strong winds and low temperatures without protective clothing can lead to frostbite and/or hypothermia. Wind chill values lower than minus 20 degrees can cause frostbite on exposed skin in as little as 30 minutes. Wind chill values lower than minus 35 degrees can cause frostbite on exposed skin in as little as 10 minutes. Prolonged exposure may be fatal.

Additional tips:

  • Stay inside.
  • If you must go outside, wear several layers of clothing.
  • If clothes become wet, head indoors and change layers.
