California Prepares for Potentially Historic El Niño After Statewide Emergency Declaration

Governor Newsom Declares Statewide Emergency
On September 21, 2026 Governor Gavin Newsom signed a proclamation placing the entire state under a formal emergency. The order fast-tracks permits, pre-positions flood-fighting supplies, and coordinates with the California National Guard for flood response, search-and-rescue, engineering and logistics missions. It directs the Department of Water Resources, Caltrans and environmental agencies to prioritize projects that protect vulnerable communities, highways and critical infrastructure ahead of the winter storm season. Separate emergency proclamations were issued for counties already dealing with recent storm damage, and the governor terminated 34 older emergency orders.
Background & Context
El Niño is a climate pattern in which unusually warm sea-surface temperatures develop in the eastern tropical Pacific, shifting the jet stream and increasing atmospheric moisture. Federal forecasters, including NOAA’s Climate Prediction Center, report a greater than 90 % chance of a “very strong” El Niño this fall-winter and a 75 % probability it could reach historic strength—the strongest since 1950. Scientists note a “coastally trapped Kelvin wave” is already elevating sea levels along Southern California, and an 18-year high-tide cycle will amplify king-tide flooding. Recent research in *Science* indicates El Niño events are now more than 36 % stronger than in the pre-industrial era.
Data & Statistics
- Probabilities: >90 % chance of a very strong El Niño; 75 % chance of historic strength (NOAA).
- Preparedness supplies: The Department of Water Resources has pre-positioned 4.4 million sandbags, 400,000 tons of rock, and other flood-control material at 68 locations in 8 warehouses statewide.
- Sea-level rise: Forecasts anticipate a 6-inch to 2-foot increase in coastal water levels during the El Niño season.
- Potential impact: Modeling suggests an additional 170,000 people and $60 billion in property could be affected compared with a non-super El Niño year (UC Santa Cruz).
Official Statements & Responses
Local officials, such as Orange County Supervisor Katrina Foley and Long Beach City Manager Tom Modica, said the emergency enables expedited sand-movement projects and shoreline reinforcement before the rains arrive.
Why It Matters
The projected hazards include heavy rain, strong winds, deep mountain snow, flooding, landslides, debris flows, large waves and coastal flooding—especially when storms coincide with king tides. Past El Niño winters (e.g., 2015-16, 1982-83) produced billions of dollars in damage, extensive beach erosion and widespread power outages. The current event threatens transportation corridors, agricultural lands and coastal economies, while raising the risk of mudslides in burn-scarred hillsides. Early mobilization aims to reduce response time, protect lives and limit property loss.
Conflicting Reports & Gaps
Sources differ on the certainty of impacts. Forecasts vary in projected sea-level rise and wave energy, and no agency has released precise rainfall totals for the upcoming season.
