Smoke advisory issued for parts of San Diego County due to 458-acre vegetation fire in Tecate

A vegetation fire that broke out Wednesday in Tecate has been affecting the air quality in some parts of the county, officials said.

The Border 20 fire is 458 acres and "completely within Mexico," fire officials said. A smoke advisory was issued for Dulzura and Potrero as "overnight winds will become light and begin blowing the smoke toward the northwest into San Diego County."

At 6:33 p.m., Cal Fire posted on the X platform, formerly known as Twitter, that the fire was 458 acres and only burning south of the U.S.-Mexico border. The blaze is still a threat to the U.S., but resources are on scene, and retardant is available if the fire travels north.

Cal Fire spokesperson Mike Cornett first said the fire was burning in Mexico and the U.S. After "updated mapping and intelligence products," the agency clarified the fire's location on X.
