Southern California could face intense rainfall and flooding if a 'Super El Niño' develops later this year. Areas near the San Jacinto Mountains and desert regions are particularly vulnerable, as past events have shown catastrophic flooding in these locations. While El Niño can help alleviate drought conditions, its effects are unpredictable, and residents should not rely solely on it to resolve water deficits. The potential for severe storms and infrastructure strain underscores the need for preparedness, especially in flood-prone areas.
