What Does FZFG Stand For?

FZFG stands for Freezing Fog METAR Code

FZFG, or Freezing Fog METAR Code, is a meteorological term used in aviation weather reports to indicate the presence of freezing fog. This phenomenon occurs when water droplets remain in a liquid state at temperatures below freezing, leading to the formation of ice when the droplets come into contact with surfaces. The presence of FZFG in METAR reports signifies potentially hazardous flying conditions, as it can significantly reduce visibility and create icy conditions on runways and taxiways. Understanding and interpreting FZFG is essential for pilots and aviation personnel to ensure safe flight operations in adverse weather situations.
