Cold weather advisory
A cold weather advisory (formerly known as a wind chill advisory until October 2024) [1] is a hazardous weather statement issued by Weather Forecast Offices (WFO) of the National Weather Service (NWS) in the United States to alert the public that temperatures or wind chills are forecast to reach values low enough that it poses a threat to human health and life if adequate protection is not taken against hypothermia and frostbite. The exact criteria meriting the issuance of an advisory varies from state to state, and areas prone to colder temperatures will often require colder temperatures/wind chills before issuing an advisory.[2]
Example
