States like Colorado, New Mexico, Idaho, Oregon and Washington have experienced devastating blazes that have killed at least 44 people this year, according to a count by CNN.

In Colorado, the two largest wildfires in state history have burned more than 400,000 acres in the last few weeks.

Fires threatening more than 20,000 structures

As of late Tuesday night, the Blue Ridge Fire in Orange County's Yorba Linda had charred 14,334 acres, according to an update from Cal Fire.

No containment has been reported.

The update said that seven structures were damaged, and one was destroyed in the blaze, which is also threatening more than 20,000 other structures.

Extreme fire weather in the area, including high winds between 30 to 50 mph pushed the flames into Chino Hills, northeast of Yorba Linda, on Tuesday.

While some evacuation orders have been lifted for parts of Irvine, approximately 70,000 residents are still under evacuation orders, Orange County Fire Authority PIO Captain Jason Fairchild told CNN.

Mandatory evacuation orders remain in the areas of Yorba Linda, Chino Hills, the Sleepy Hollow area of Brea, Olinda Ranch, and Brea Hills, according to Cal Fire.

Nearly 30,000 residents from Yorba Linda and Chino Hills were evacuated as of Tuesday morning, according to the Chino Valley Fire Department.
