VISTA, Calif. — Officials said a series of small fires broke out in Vista on Monday night, prompting the evacuation of some local apartments and forcing the closure of the westbound carriageway on SR-78.

According to the Vista Fire Department, the fire started at around 8:45 pm, burning 3-4 acres of land, but the speed of its forward spread has stopped. Firefighters said the fire had five different starting points on the highway westbound from Sycamore Avenue to Mar Vista Drive.

22 units spanning multiple agencies were assigned to control the fire.

Vista firefighters said that during the process, some apartment units were evacuated, but no buildings caught fire. According to the agency, two vehicles were burned in a parking lot near the highway.

When the staff was on site, the Sycamore Avenue ramp to westbound SR-78 was closed. According to the California Highway Patrol, the eastbound lane of Mar Vista was also required to be closed to cut down palm trees that might fall into the road.

It is not clear how the fire started.
