South Korean authorities have issued warnings regarding sudden and large rogue waves, known as "neulwol," impacting coastal areas. These waves, described as appearing unexpectedly and rapidly engulfing shorelines, pose a significant threat to safety. The phenomenon is likened to a predator swiftly ambushing its prey, emphasizing the speed and stealth of these surges. Officials are urging increased vigilance along the coast, as the waves can appear without prior warning and reach considerable heights—comparable to multi-story buildings. The alerts aim to protect individuals and prevent potential accidents caused by the unpredictable nature of these powerful waves. Further monitoring and public safety announcements are expected as conditions evolve.
