San Diego Officials Warn of Potential Flooding Amid Strong El Niño Season
US · Published Aug 19, 2026
San Diego city leaders and emergency officials are urging residents to prepare for a potentially strong El Niño season, which could bring heavy rainfall and significant flooding.
El Niño, a natural warming of parts of the central Pacific Ocean, influences global weather patterns and is expected to reach historic strength this year, according to the U.S.

Impact & Risks

The anticipated El Niño season could lead to severe flooding, particularly in areas with a history of water-related damage, such as Southcrest, Encanto, and other parts of southeast San Diego. Over 15,000 acres and 6,900 structures in San Diego are located in FEMA-designated flood hazard zones, but flooding can also occur outside these areas. Residents in high-risk zones are especially vulnerable and are advised to take immediate precautions. Past flooding events, such as the January 2024 floods, caused significant damage and displacement, highlighting the potential severity of the upcoming season.
