A wind chill watch is a weather watch formerly issued by the National Weather Service of the United States when the wind chill could reach dangerous levels within the next 12 to 48 hours; as of October 2024 it has been re-named "extreme cold watch." The exact definition required to issue a watch varies from state to state or from National ...
