LOS ANGELES—Firefighters worked in the air and on the ground Friday to halt a new brush fire called the Archer fire in the Granada Hills neighborhood that briefly prompted an evacuation order as it advanced toward homes.

The fire was reported at 10:25 a.m. Friday in the 17200 block of West Sesnon Boulevard in the San Fernando Valley area, according to the Los Angeles Fire Department’s Margaret Stewart. It was first reported at two to three acres, but quickly grew to 20 acres.

Broadcast video showed firefighters establishing structure protection as police evacuated homes in the neighborhood, with trucks and a bulldozer on the ground and air drops in the nearby brush.

Mandatory evacuations were ordered shortly after 11 a.m. for residents at Balboa Boulevard and Interstate 5 on the east, Tampa Avenue on the west, Sesnon on the south and Sunshine Canyon Road on the north. They were downgraded to warnings at 11:42 a.m.

Evacuation warnings were issued for the area between Tampa Avenue and Balboa Boulevard, and between Rinaldi and Sesnon. They were lifted at 11:42 a.m.
