cold weather warning
An extreme cold warning is a weather warning issued by Environment and Climate Change Canada (ECCC) and by the United States' National Weather Service (NWS) to inform the public about active or imminent severe cold temperatures in their local region.
In April 2014, ECCC replaced the "wind chill warning" with an "extreme cold warning." In the older system a wind chill warning for Southern Ontario and Atlantic Canada was issued when the wind chill dropped to -35. Thus a temperature of −37 °C (−35 °F) with no winds would not require a warning be 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 −30 °C (−22 °F) temperatures to −55 °C (−67 °F) in parts of the Arctic.
On October 1, 2024, the NWS replaced the "wind chill warning" with the "extreme cold warning." The standards governing issuance are set by local NWS offices. The step below an extreme cold warning is an "extreme cold watch," which itself replaced the "wind chill watch" in October 2024.
