A brush fireTuesdayafternoon near South Beach scorched nearly five acres and caused minor delays for motorists traveling down U.S. Highway 101.

No accidents or injuries were reported, and the fire is currently under investigation by Cal Fire officials.

Cal Fire Battalion Chief Tim Devos said the fire was reported at1:14 p.m.across the highway from Sand Mine Road. Flames burned 3andndash;4 acres before ground crews at the scene contained it at2:20 p.m.

Smoke from the fire caused limited visibility for motorists, prompting California Highway Patrol officers to help with traffic control at the scene, Devos said.

Three air tankers attempted to put out the flames, but fog prevented them from getting close to the fire, Devos said.

The fire is under investigation. Devos said all leads would be pursued, including the possibility of arson.

Another brush fire ignited less than a mile south of that location 10 days before. Started by a campfire on the beach, the half-acre blaze on Aug. 23 was extinguished with the help of an air tanker.
