In the TAF "PROB40 2024 2SM FZRA", what does "FZRA" indicate?

In the Terminal Aerodrome Forecast (TAF), the notation "FZRA" specifically indicates "Freezing Rain." This term describes precipitation that falls as rain but freezes upon contact with surfaces that are at or below freezing temperatures. The presence of freezing rain in a TAF can signal significant hazards for aviation, as it can lead to ice accumulation on aircraft, runways, and other surfaces, impacting safety and operations at the airport.

Understanding weather codes in TAFs is crucial for flight planning and safety. The TAF provides critical information for pilots to assess potential weather-related risks. In this context, "FZRA" is specifically differentiated from other precipitation types like freezing drizzle (which is indicated by "FZDZ"), fog (indicated by "FG"), or other weather phenomena. Recognizing these distinctions is important for pilots to make informed decisions about flight operations.
