The extreme El Niño event poses significant risks to California and the Southwest. Coastal flooding is already affecting areas like Newport Beach and Long Beach, with water levels running 1–2 feet above predictions. King tides in November, December, and January could exacerbate flooding, especially during storms. Inland areas face elevated risks of flash flooding, particularly in regions prone to atmospheric rivers. The Sierra Nevada may experience abundant precipitation, but warmer temperatures could limit snowpack at lower elevations. Marine ecosystems are also at risk due to record-high water temperatures. Overall, the likelihood of record-breaking wet conditions and severe weather is substantially higher than usual.
