The more-than 23-hundred-acre Pinnacles Fire in San Bernardino National Forest is burning northeast of Lake Arrowhead. It's 80 percent contained and crews say they hope to fully surround it by tomorrow evening.

Another fire is burning ten miles north of La Canada Flintridge in Angeles National Forest. It's 75 percent contained and crews say they hope to fully contain it by tonight.

The red flag warning is being brought on by hot, dry Santa Ana winds that are expected to arrive today and last through the weekend.

Officials say winds could reach 65 miles per hour at times tomorrow.
