Strong El Niño Expected to Bring High Flood Risks to Southern California
A strong El Niño event is developing in Southern California, with experts predicting it could be the strongest ever observed (LAist, 2026-08-18). El Niño, a natural climate pattern, warms the eastern tropical Pacific and often leads to extreme weather, including heavy rainfall. This year, the phenomenon coincides with the highest tides in nearly two decades, further elevating flood risks. Climate scientist Daniel Swain warns of a 'very high and almost guaranteed' risk of coastal flooding, compounded by human-caused global warming, which has already raised sea levels by up to a foot along California's coast over the past century. Inland areas near creeks and rivers are also at risk due to potential extreme rainfall.
