The anticipated El Niño conditions could lead to severe weather impacts across San Diego County, including heavy rain, urban flooding, mudslides, and coastal erosion. These events may result in road closures, power outages, and damage to critical infrastructure. Communities in low-lying areas and those near waterways are particularly vulnerable to flooding and landslides. The strain on stormwater systems could exacerbate these risks, potentially leading to significant disruptions in daily life. Local officials have emphasized the importance of early preparation to mitigate these risks and protect lives and property.
