The anticipated El Niño could have widespread consequences for Southern California residents, particularly those in flood-prone areas and coastal communities. Heavy rainfall may lead to urban flooding, while elevated sea levels could exacerbate coastal erosion and threaten infrastructure. Mudslides are also a significant risk in areas with steep terrain, especially where vegetation has been compromised by previous wildfires. These hazards could disrupt transportation, damage property, and pose safety risks to residents. While the event's exact severity is uncertain, the potential for record-breaking conditions underscores the need for preparedness.
