Which type of weather condition is indicated by "SN" in a TAF?

In a TAF, the abbreviation "SN" specifically indicates snow. This code is part of the standardized METAR and TAF reporting language used globally, which enhances clarity and consistency in aviation weather reports. Each weather phenomenon has its own designated abbreviation to ensure pilots and meteorologists can quickly and easily understand the weather conditions expected at an airport.

Snow, indicated by "SN," reveals important information for flight operations, including potential impacts on visibility, runway conditions, and the overall safety of aircraft movements. This abbreviation leads to quicker assessment and preparation for pilots and ground crews, ensuring that they can make informed decisions regarding takeoff, landing, and any necessary precautions.

The other choices represent different weather phenomena, each with its own unique abbreviation: "RA" for rain, "FG" for fog, and "TS" for thunderstorms. Knowing these distinctions is crucial for interpreting a TAF accurately and responding appropriately to weather conditions.
