El Niño is characterized by warmer than average sea surface temperatures in the Eastern equitorial Pacific. The interactions between a warmer ocean and the atmosphere affect weather around the world. A strong El Niño in the Pacific Ocean this year has the potential to become one of the most powerful on record. Models are predicting El Niño will peak in the late fall or early winter. Impacts due to flooding, unusually large waves, heavy precipitation, and erosion are expected in Southern California. The resources below can help us understand what to expect and how to prepare.
