The anticipated El Niño could lead to significant disruptions across California. Southern California faces heightened risks of landslides, flooding, and coastal erosion due to above-average rainfall. Marine ecosystems may experience reduced plankton levels, harmful algal blooms, and shifts in species distribution, including increased sightings of sharks and other tropical marine life. Coastal communities should prepare for potential high-tide flooding and infrastructure damage. Historical data shows that very strong El Niño events have doubled annual rainfall in areas like downtown Los Angeles, underscoring the potential severity of this year's event.
