California is gearing up for a potentially historic El Niño, as Governor Gavin Newsom declared a statewide state of emergency on September 21, 2026. This proactive measure aims to prepare the state for severe winter storms and flooding expected to accompany the climate phenomenon.
Why it matters: California's emergency declaration signals serious concerns over the impacts of an intensifying El Niño, which could lead to widespread flooding and infrastructure damage.
The National Oceanic and Atmospheric Administration (NOAA) indicates a greater than 90% chance of a very strong El Niño event this fall and winter, with a 75% chance of it reaching historic strength.
El Niño typically brings wetter winters to California, increasing the risk of flooding, landslides, and coastal erosion.
Experts warn that El Niño's effects are compounded by climate change, making storms more intense and unpredictable.
Driving the news: The emergency declaration allows state agencies to mobilize resources quickly, preparing communities for the anticipated severe weather.
Newsom's proclamation directs agencies to stage emergency supplies, protect vulnerable communities, and prepare roads and infrastructure for potential flooding.
The California National Guard will be on standby to assist with flood response and search and rescue operations if necessary.
State officials highlighted the importance of early preparation, stating that flooding can occur even in years with below-average rainfall.
State of play: Coastal cities have already begun to experience the effects of high surf and flooding linked to Hurricane Marie, providing a preview of what could come this winter.
Recent reports indicate that several coastal California cities faced flooding and coastal erosion due to storm surges associated with Hurricane Marie.
Officials are particularly concerned about the potential for heavy rain and strong winds, which could exacerbate existing vulnerabilities.
California has positioned 4.4 million sandbags statewide and conducts inspections of 1,600 miles of levees in its flood-control system.
The big picture: The current El Niño is already breaking temperature records, raising concerns about its intensity and potential impacts on the state's weather patterns.
A study published in the journal Science found that El Niño events are now over 36% stronger than before the industrial era, with this trend accelerating over the last 40 years.
This year's El Niño is expected to significantly influence weather patterns, potentially leading to torrential downpours and increased flood risks.
Forecasters predict that the Pacific Ocean's unusually warm temperatures will contribute to more extreme weather conditions across the state.
What they're saying: Officials are urging Californians to take the threat seriously and prepare accordingly.
“We are preparing for this El Niño early because every Californian deserves to be safe in their home, connected to their community, and protected when severe weather comes,” Newsom said.
California Secretary of Natural Resources Wade Crowfoot emphasized the urgency of readiness, stating, “California is already taking steps now to protect communities from a potentially historic El Niño.”
Mayor Todd Gloria expressed support for Newsom’s early action, stating that the city will work closely with state and local partners to prepare San Diego for severe weather.
By the numbers: The scale of preparation reflects the seriousness of the situation.
California has mobilized 4.4 million sandbags to mitigate flooding risks across the state.
The state’s flood-control system includes inspections of 1,600 miles of levees to maintain safety and efficacy.
Emergency supplies are being staged to facilitate rapid response to flooding and other weather-related emergencies.
What's next: As the winter season approaches, state agencies will continue to monitor El Niño developments closely.
Officials will expand multilingual public outreach efforts to inform communities about preparedness for severe weather, power outages, and evacuation protocols.
Californians are encouraged to prepare their homes and families for potential weather impacts, including flooding and power outages.
The state remains ready to request federal assistance if the situation escalates and exceeds local capabilities.
As California braces for what could be one of the most intense El Niño seasons on record, the emphasis on preparation and community support remains a top priority for state leaders.
