Los Angeles city officials are bracing for a potentially severe El Niño season, with Mayor Karen Bass outlining preparations the city is taking ahead of anticipated heavy rainfall and powerful weather.
Speaking at a Monday morning news conference alongside National Weather Service personnel and local officials, Bass acknowledged that coastal areas have already experienced significant impacts. “We’ve already seen powerful surf and coastal erosion cause damage,” Bass said, emphasizing the need for immediate action, adding, “That’s why we’re acting now before the storms arrive.”
The city's preparations include mobilizing emergency response teams. Crews are actively inspecting and reinforcing vulnerable sections of the city, focusing particularly on burn areas and prioritizing hillside communities known to be susceptible to mudslides and erosion.
For residents in immediate coastal proximity, the city is delivering sand to local fire stations, which can be used to protect homes from potential flooding. Mayor Bass also urged all residents to sign up for emergency alerts via notifyla.org and to download the city’s “my311” app. The app allows residents to quickly report issues such as downed trees or power lines, enabling city crews to respond efficiently.
El Niño is a natural climate pattern characterized by warmer-than-average ocean temperatures in the tropical eastern Pacific. This shift in ocean conditions can dramatically alter global weather patterns, leading to wetter, more intense, and more powerful winters for California.
This year’s El Niño event is already showing signs of exceptional strength. A study published last month in the journal *Science* found that El Niño events are now more than 36% stronger than they were before the industrial era. This trend has accelerated over the last 40 years, a period coinciding with a warming planet.
Officials are warning that this cycle could bring heavy rain, strong winds, significant mountain snow, and coastal flooding to Southern California. The developing El Niño is not only breaking records but is expected to continue strengthening, potentially becoming the strongest in recorded history.
State officials have echoed these warnings, noting a greater than 90% chance of a very strong event developing this fall and winter, with a 75% chance it could reach historic strength. Some forecast models suggest this developing El Niño could be the largest in the roughly 150-year observational record. The warmer waters and changing currents associated with such a strong event can also bring tropical and subtropical marine species well north of their typical ranges, potentially surprising local beachgoers and anglers.
California has already declared an El Niño emergency, a measure designed to mobilize state resources proactively to mitigate any potential impacts on communities across the region.
