SAN YSIDRO, Calif. -- U.S. Customs and Border Protection said a "large-scale operational readiness exercise" could result in minimal processing delays at the San Ysidro Port of Entry on Thanksgiving Day.
The exercise is planned to begin around 2 p.m. Thursday and last 10 minutes.
"CBP is continually assessing the capabilities of our facilities and have been making - and will continue to make - necessary preparations. These include participating in operational readiness exercises and the mobilization of resources as needed to ensure the facilitation of lawful trade and travel," the federal law enforcement agency said in a statement.
CBP also confirmed the enforcement presence is only going to grow at the border.
More than 500 CBP officers and nearly 900 additional U.S. Border Patrol agents have been deployed to California, Arizona and other areas in the U.S. to provide even more support at ports of entry.
