The anticipated wetter conditions could lead to several risks for California, including coastal flooding, mudslides, and higher sea levels. Atmospheric rivers may bring heavy rainfall, increasing the potential for flash flooding in urban and low-lying areas. The Sierra Nevada could see major snow events, which may disrupt travel and infrastructure. On the positive side, the increased precipitation could reduce wildfire risks across the state. However, the disruption of ocean upwelling due to El Niño may impact marine ecosystems, raising concerns for local fisheries and sea life.
