California braces for a powerful El Niño and its potential impacts

California may experience a "super" El Niño, potentially the strongest this century, bringing significant weather shifts. This rare event involves warmer-than-average Pacific waters, increasing the likelihood of wet winters in Southern California, which can replenish water supplies and reduce wildfire risk. However, it also raises concerns about flooding and coastal erosion. While strong El Niños can bring beneficial rain, their exact impact is uncertain, as seen in past events with varied outcomes.
