Millions Of Americans Face Blackout Warning As ‘Devil Winds’ Reach 80 MPH
More than 20 million Americans are bracing for potentially devastating winds as Southern California faces a dangerous weather emergency that could leave entire communities without electricity and fuel another round of destructive wildfires.
The powerful Santa Ana winds, ominously nicknamed “devil winds,” are expected to unleash gusts reaching 80 mph beginning Thursday, with some forecasts warning that speeds could climb as high as 90 mph.
The dangerous conditions are expected to continue through Saturday, putting millions of residents across Los Angeles, Ventura, Orange, San Diego, Riverside and San Bernardino counties on alert.
Forecasters warn that the hurricane-force gusts could uproot trees, damage homes, knock down electrical equipment and create hazardous driving conditions.
The National Weather Service has issued a stark warning as Southern California prepares for another potentially dangerous stretch of extreme weather.
‘Damaging winds will blow down trees and power lines. Widespread power outages are expected. Travel will be difficult, especially for high-profile vehicles.’
With wind speeds potentially exceeding those of a Category 1 hurricane, authorities are urging residents to prepare for significant disruptions.
But falling trees and damaged power lines aren’t the only concerns.
The combination of powerful winds, extremely dry conditions and soaring temperatures has created a dangerous recipe for rapidly spreading wildfires.
Temperatures across Los Angeles and San Diego could climb into the 90s, further drying vegetation already vulnerable to ignition.

AccuWeather warned that utility companies could deliberately cut electricity to certain communities in an effort to prevent electrical equipment from sparking catastrophic fires.

‘Utilities may temporarily shut off electricity in areas facing dangerous fire weather to reduce the risk of power equipment sparking wildfires.’
Those preventative shutdowns could leave residents facing blackouts even in areas where power lines remain intact.
The threat is especially troubling given California‘s devastating wildfire history.
In January 2025, intense Santa Ana winds helped fuel the deadly Palisades and Eaton fires, contributing to widespread destruction across Los Angeles County.
Those disasters left entire neighborhoods in ruins, destroyed thousands of structures and claimed dozens of lives.
Now, similar weather conditions are raising fears that another spark could quickly spiral into a major emergency.

The National Weather Service warned that conditions could become ‘favorable for extreme fire behavior which would threaten life and property.’
Red Flag Warnings have been issued across much of Los Angeles and Ventura counties, beginning Thursday morning and continuing until Saturday evening.
Communities facing heightened danger include Malibu, the Santa Monica Mountains, Santa Clarita Valley, San Fernando Valley, Calabasas and surrounding foothill neighborhoods.
The strongest winds are expected Friday, when widespread gusts around 60 mph could sweep through portions of Southern California.
Santa Ana winds develop when high-pressure systems over the interior western United States push dry air toward the Pacific Coast.
As that air descends through mountain passes and canyons, it warms and becomes even drier, creating conditions capable of turning small fires into fast-moving infernos.
Residents are being urged to avoid outdoor burning, exercise caution with equipment that produces sparks and prepare emergency evacuation plans.
Those living near wildfire-prone areas should remain especially vigilant as dangerous conditions develop.
With millions potentially facing blackouts and firefighters confronting another serious wildfire threat, Southern California is entering a weekend where a single spark could have devastating consequences.
