To what does "WSHFT" refer in METAR remarks?

"WSHFT" in METAR remarks stands for "Wind shift." This indicates a notable change in wind direction over a short period, which can be an important element for pilots and meteorologists as it may signify changes in weather patterns or the approach of a frontal system. Wind shifts can affect flight operations, potentially altering flight paths or procedures, especially during takeoff and landing. Understanding "WSHFT" helps aviation personnel anticipate and respond to dynamic atmospheric conditions that could impact safety and operational efficiency.
