Waves slammed into beaches along Argentina’s northern coast, including Santa Clara del Mar, Mar Chiquita Partido and Mar de Cobo. The freak waves, known as a meteotsunami, killed a 29-year-old man and injured 35 others, officials said. Meteotsunamis are generated by meteorological conditions. Air-pressure disturbances, the kind linked to fast-moving weather events like severe thunderstorms and squalls, drive meteotsunamis. The storm generates a wave that pushes toward the shore. The wave can become dangerous as it reaches shallow water because it slows down and increases in height and intensity.
