Explanation:
Weather reporting moved from manual visual signals to automated, digital data in the late 1980s. As automated weather observing systems and standardized electronic feeds (like METARs) became widespread, stations could rely on electronic data rather than displaying on-site weather flags and lights. This shift reduced the need for manual signals and was formalized during that period, making the late 1980s the correct timeframe. The earlier decades still depended more on on-site visuals, while the 1990s and 2000s came after automation had already been adopted.
