Emergency proclamation unlocks response tools

San Diego Mayor Todd Gloria proclaimed a local emergency in the city on Friday, Oct. 2, 2026, in anticipation of potentially severe weather associated with the 2026-2027 El Niño season, according to KPBS Public Media.

The action strengthens the city's ability to prepare for and respond to potential flooding and other weather-related impacts, according to the City of San Diego Official Website.

The proclamation follows emergency declarations made by California and the County of San Diego, according to KPBS Public Media.

By proclaiming a local emergency, the city is now able to use emergency authorities available under state and local law and supports the city's ability to seek state and federal assistance, according to a statement from Gloria's office cited by KPBS Public Media.

"Being ready for severe weather means doing the work now, before storms arrive," Gloria said.

Gloria said the city had been working for months on clearing storm channels, strengthening infrastructure, coordinating emergency plans and helping San Diegans prepare, according to KPBS Public Media.

Gloria said declaring a local emergency now gives the city additional tools and flexibility to build on that work and respond quickly when severe weather arrives, according to KPBS Public Media.

Gloria said the city was doing everything it can today to keep San Diegans safe tomorrow, according to KPBS Public Media.

Council ratification decides how long order lasts

The proclamation will remain in effect for seven days unless ratified by the San Diego City Council, according to KPBS Public Media.

The council will consider ratification at its regular meeting on Tuesday, according to KPBS Public Media.

The City of San Diego Official Website identifies that meeting date as Tuesday, Oct. 6.

If the council ratifies it, it will remain in effect until the council votes to end it, according to KPBS Public Media.

The City of San Diego Official Website phrases the endpoint as remaining in effect until the City Council terminates it.

Working group has coordinated since summer

San Diego's Office of Emergency Services has been coordinating an El Niño Preparedness Working Group since this summer in an attempt to identify weaknesses and strengthen plans, according to KPBS Public Media.

The City of San Diego Official Website describes the effort as a Citywide El Niño Preparedness Working Group bringing together departments and operational teams.

The working group was formed to identify vulnerabilities, strengthen emergency plans and coordinate with regional partners, according to the City of San Diego Official Website.

As part of that work, the city launched Stay Ready, San Diego, a public preparedness campaign to provide residents and businesses with information and resources to prepare for severe weather and other emergencies, according to the City of San Diego Official Website.

KPBS Public Media also identifies Stay Ready, San Diego as the public preparedness campaign providing emergency preparedness information to residents and businesses.

What city hall expects this winter

The City of San Diego Official Website says the city is preparing for the possibility of heavier-than-usual rainfall, stronger surf, beach erosion, flooding, mudslides, power outages, downed trees and impacts to public infrastructure during the El Niño season.

Officials warn this El Niño cycle could bring heavy rain, strong winds, mountain snow and coastal flooding, according to KPBS Public Media.

High surf was already visible Oct. 1, 2026, when high surf crashed over rocks at Robert Frazee State Beach, north of Tamarack near Carlsbad Village Drive, in a photo credited to Carolyne Corelis / KPBS and described by KPBS Public Media.

The looming El Niño event is already breaking records, and forecasters expect it to continue to strengthen, potentially becoming the strongest in recorded history, according to KPBS Public Media.

Why forecasters call this El Niño potentially historic

El Niño is a natural climate pattern marked by warmer-than-average ocean temperatures in the tropical eastern Pacific, which can shift weather patterns and bring wetter, more intense, powerful winters to California, according to KPBS Public Media.

A study published in the journal Science last month found El Niño events are now more than 36% stronger than before the industrial era, with that trend accelerating over the last 40 years as the planet warms, according to KPBS Public Media.

State officials said El Niño is strengthening, with a greater than 90% chance of a very strong event this fall and winter and a 75% chance it could reach historic strength, according to KPBS Public Media.

Some forecast models predict the developing El Niño could be the largest in the roughly 150-year observational record, according to KPBS Public Media.

Warmer waters and changing currents can bring tropical and subtropical species well north of their typical ranges, according to KPBS Public Media.

January 2024 floods shape current response

Gloria pointed to the devastating floods of January 2024 as a lesson driving current action, according to KPBS Public Media.

"San Diego learned painful lessons from the devastating floods of January 2024."

Gloria said the city knows how quickly extreme weather can upend lives, damage homes and overwhelm neighborhoods, according to KPBS Public Media.

Gloria said city teams will continue working across departments and with regional partners to protect San Diegans and keep the public informed, according to KPBS Public Media.

Gloria urged every resident and business to use this time to prepare, stay alert and take weather warnings seriously, according to KPBS Public Media.

Gloria said preparedness is a shared responsibility and the actions taken now can protect lives and property in the months ahead, according to KPBS Public Media.

What households and businesses are asked to do now

San Diegans should use the time before significant rain arrives to prepare their homes, businesses and families, according to the City of San Diego Official Website.

Residents are encouraged to know whether they live in a flood-prone area, make an emergency plan, prepare an emergency kit and stay informed about changing weather conditions, according to the City of San Diego Official Website.

Through Stay Ready, San Diego, residents can find information and resources to prepare their households, businesses and families for severe weather and other emergencies, according to the City of San Diego Official Website.

For preparedness information and resources, the city directs residents to visit sandiego.gov/elnino, according to the City of San Diego Official Website.

KPBS Public Media also lists sandiego.gov/elnino as the source for preparedness information and resources.
