El Niño's effects on California vary by region, with Southern California likely to experience heavy rainfall and urban flooding, while Northern California may face inconsistent precipitation patterns. Central California and the Sierra Nevada could see a mix of rain and snow, with risks of increased runoff and potential flooding. Coastal areas are vulnerable to high surf, beach erosion, and flooding, especially when high tides coincide with storms. Burn-scarred regions face heightened risks of debris flows, and mountain areas may encounter hazardous travel conditions due to heavy snow and avalanches. Additionally, the combination of strong winds, falling trees, and flooding could lead to power outages, disrupting essential services such as refrigeration, communication, and heating systems (Anker SOLIX, 2026).
