During the cold season, it is quite common to hear the term freezing fog used during your standard briefing especially if you fly in Canada or the northern third of the U.S. When looking online or contained in a DUATs briefing, you may also see freezing fog appear in a routine or special surface observation designated by the abbreviation FZFG.

In this workshop we will discuss the criteria for freezing fog and how it is determined by the surface observing equipment and if this represents any significant hazard for air frame icing.
