"We have categorized this event as abnormal due to the height of the wave, which could reach 5 meters (16.4 feet) during high tides," said Lieutenant Felipe Rifo Esposito, Head of the Maritime Meteorological Center of Valparaiso. "One of the factors for this categorization is the New Moon on August 21, aligning with the Sun and Earth and generating the highest tides of the month."

"Since the swells will come from the southwest, we expect to most intense conditions to occur along our northern coast, where the bays are unprotected from that direction," Espósito said.

Authorities warned all residents that it is necessary to act with prudence and caution, to respect the established rules and avoid coastal traffic and rocky areas. "Do not enter the sea during swells as beaches will be unsuitable for swimming, and do not participate in nautical and sports activities without proper authorization."
