Mexico sent more than 70 firefighters and disaster relief workers to help local efforts. The firefighters will form handcrews.
Canada has also sent crews to Los Angeles to help get control of the multiple wildfires that have already destroyed thousands of structures and killed at least 16 people.
On top of the crews from all across California, states like Texas, New Mexico, Colorado, Utah, Nevada, Arizona, Oregon and Washington have sent firefighters.
Newsom also announced on Saturday that he increased California National Guard personnel to almost 1,700 servicemembers.
“We are continuing to rush in resources to rapidly respond to the firestorm in Los Angeles fueled by hurricane-force winds,” the governor said in a statement. “The men and women of the California National Guard are working day and night to help Los Angeles residents during their greatest time of need.”
Earlier this week, Los Angeles County Fire Department Chief Anthony Marrone said all county fire departments are at “a drawdown, with no fire apparatus or additional personnel to spare.”
There are more than 70 aircraft and more than 1,600 fire engines, water tenders and dozers.
At least 11 people have been killed after several fires burned across parts of the broader Los Angeles area this week. Two of the devastating fires are the Eaton Fire, burning above Altadena, and the Palisades Fire, burning in the coastal community of Pacific Palisades.
More than 100,000 people remain under evacuation orders as the fires have burned more than 60 square acres.
