Red Flag Warnings (RFW)
A Red Flag Warning (RFW) is a term that has been used since the 1960s by the National Oceanic and Atmospheric Administration (NOAA) National Weather Service (NWS) fire weather forecasters to alert forecast users to an ongoing or imminent critical fire weather pattern. The warning is issued as needed for anywhere in the country.
