Crews Work To Contain Wildfire Across U.S.-Mexico Border

SAN DIEGO, CA — Crews continued to work Monday to contain a wildfire that crossed over the Mexico border from San Diego County.

The blaze, called the Border 53 Fire, sparked at 12:35 p.m. Saturday near Buttewig Canyon, in the south slope of Otay Mountain, according to Cal Fire.

As of Monday morning, the 400-acre fire had blackened 250 acres in the U.S. and 150 acres in Mexico, Cal Fire said on social media. The blaze was 60% contained.

"Fire activity last night was low, due to more humidity in the air from the marine layer," Cal Fire said in the latest incident report. "Firefighters will continue to work on increasing containment throughout the day."

There were 35 personnel assigned to the fire Monday, including two engines, one hand crew, one water tender and four other resources.
