What does VCSH represent in a METAR report?

In a METAR report, VCSH stands for "Vicinity of Showers," which indicates that there are rain showers occurring nearby but not directly at the station reporting. This designation can be crucial for pilots in understanding the weather conditions surrounding their flight path. The terminology helps to convey information about precipitation that could affect visibility or conditions at the airport, despite the exact location of the showers not being on the airfield itself.

Understanding this term is important for safe operation and flight planning, as it provides insight into potentially changing weather conditions that may not be immediately evident from other parts of the report.
