Strong Santa Ana winds near Los Angeles are fueling some of the biggest wildfire threats in years across Southern California.

Relentless wind gusts of 50 to 70 mph have created a perfect storm of conditions, leading to rapid fire spread and widespread evacuations.

These conditions led to the explosion of the destructive Mountain Fire in Ventura County on Wednesday. In a matter of hours, it consumed nearly 15,000 acres. Mandatory evacuation orders were issued for parts of Ventura, Camarillo, Moorpark and Somis, California.

Officials say the Mountain Fire that broke out Wednesday morning in Ventura County has not yet been contained and has injured several people.

At least 800 firefighters are on the scene, according to the Ventura County Fire Department.

Firefighters continued their tireless fight against the flames at night, employing a combination of ground crews and night-flying helicopters.

Hundreds of mutual aid crews across California continue to arrive on scene as the rapidly advancing fire has impacted numerous structures.

Damage estimates are expected to begin Thursday. The cause of the fire is under investigation.

Another dangerous fire, the Broad Fire, burns in the Malibu area and threatens homes and business.

The FOX Forecast Center said Santa Ana winds peaked Wednesday morning, but periods of strong, gusty winds from the northeast to the east will continue into Thursday.

While conditions on Thursday won’t be as extreme, they will still be very conducive to fire spread.

The strongest gusts of 50 to 60 mph will occur along and below the coastal slopes of the mountains, including around the Mountain Fire.

The lowest daytime humidity will also be found near the fire and in Ventura and Los Angeles counties, where the National Weather Service issued a rare “particularly dangerous situation” fire weather warning.

The wildfires have also forced school closures and power outages. Smoke from the fires has also significantly affected air quality, prompting health alerts for residents.
