This year’s El Niño event could be “historically strong” and may result in severe flooding along the U.S. West Coast, including cities like Seattle and San Diego.
The U.S. Climate Prediction Center predicts a 35 percent chance of a historically strong El Niño between November and January, with a greater than 55 percent chance of at least a strong El Niño persisting through January to March 2024.
El Niño is a climate pattern that occurs every two to seven years in the Pacific Ocean, leading to warmer ocean waters being pushed towards the western coast of the U.S. This can cause disruptive weather patterns and increased high-tide flooding.
The effects of climate change, including melting glaciers and ice sheets, may exacerbate the flooding caused by El Niño events.
