Los Angeles firefighters and water-dropping helicopters stopped a fire that burned about 50 acres of brush and grass on the Sepulveda Pass along Interstate 405 early Wednesday.

The fire erupted around 2 a.m. below the hilltop homes of Bel Air but there were no evacuations and no evacuations, the Fire Department said.

Conditions in the midst of a spring heatwave were warm and dry but there was minimal wind.

Two firefighters were treated for minor injuries and returned to work, department spokesman Brian Humphrey said. The cause of the fire was under investigation.

The fire occurred in the same area as a December 2017 fire that was ignited by a cooking fire in a homeless encampment and burned six homes.

Firefighters have been chasing small blazes statewide during the spell of hot and very dry weather. The National Weather Service said a heat advisory would remain in effect through Wednesday evening for much of Southern California. Downtown Los Angeles reached a record 98 degrees Fahrenheit on Tuesday.
