California Declares State of Emergency for Historic El Niño on September 22

Governor Gavin Newsom declared a statewide emergency on September 21 as California prepares for what officials warn could be the strongest El Niño event on record. Ocean temperatures in the tropical Pacific have reached 3.04 degrees Celsius above average, surpassing the previous record set in November 2015. Forecasters estimate a 75% chance this El Niño will exceed the strength of any event since 1950, bringing heavy rainfall, strong storms, coastal flooding, and landslides across the state this winter.

What triggered the emergency declaration

Governor Newsom signed the emergency proclamation on September 21 to mobilize state resources and streamline procurement ahead of anticipated El Niño impacts. The declaration directs state agencies to lead flood-risk-reduction efforts, stage supplies such as sandbags and pumps, and pre-position critical equipment. The California National Guard is now prepared to support flood response, search-and-rescue, and logistics missions when severe weather arrives. State environmental agencies will fast-track permitting to accelerate flood mitigation and shoreline protection work.

Record ocean temperatures signal an unprecedented event

As of September 20, the Oceanic Niño Index stood at 3.04 degrees Celsius above average, the highest daily reading since records began in 1982. The previous peak occurred in November 2015 at 3.02 degrees Celsius. NOAA’s Climate Prediction Center reports a greater than 90% chance of a very strong El Niño event this fall and winter. Scientists attribute the intensification partly to climate change, with a study published in Science finding El Niño events are now 36% stronger than before the industrial era.

Supplies staged and communities urged to prepare

California has already pre-positioned 4.4 million sandbags and other flood-fighting materials in strategic locations across the state. Caltrans will stage traffic-control, road-closure, and snow-removal equipment along highways most at risk. Cal OES Director Caroline Thomas Jacobs stated that the state is bringing together state and local partners to conduct advance planning and identify potential needs before storms arrive. Forecasts indicate California could experience above-average precipitation and temperatures this winter, with potential for strong waves and higher sea levels compounding flood risks.

Why this matters for California residents

El Niño forms when tropical trade winds weaken, allowing warm ocean water to shift toward the Pacific Coast. This warming reshapes the jet stream and typically brings stormier weather to California. The current event could trigger flooding, landslides, debris flows, coastal erosion, and power outages across the state. The emergency declaration enables local governments to access critical supplies and support before severe weather arrives, helping communities and first responders prepare personnel, equipment, and resources for rapid response.

Final Thoughts

California is mobilizing emergency resources weeks ahead of what could be the strongest El Niño on record. With 4.4 million sandbags staged and a 75% forecast probability of exceeding all events since 1950, residents should expect above-average rainfall and severe winter storms through early 2027.
