What is the meaning of the code +FZRA in weather reporting?

The code +FZRA in weather reporting signifies heavy freezing rain. This abbreviation is part of the aviation weather reporting system, where specific codes are used to convey vital information about current weather conditions quickly and efficiently.

When the code features a plus sign (+), it indicates that the precipitation is at a heavy intensity. The "FZRA" portion refers specifically to freezing rain, which occurs when rain falls through a layer of air that is below freezing, causing the droplets to freeze upon contact with cold surfaces. This phenomenon can lead to hazardous conditions, such as ice accumulation on roads, airport runways, and other surfaces, which is critical for pilots and ground crews to be aware of during flight operations and ground handling.

Understanding this weather condition is essential for ensuring safety in aviation, as heavy freezing rain can significantly impact visibility and runway conditions.
