San Diego Fire-Rescue crews were responding to a brush fire burning in Barrio Logan on Wednesday.
The brush fire was burning along a canyon near Interstate 15 and Main Street and was sending a plume of thick, gray smoke over the area.
At least one structure was threatened, SDFD said. The fire appeared to be threatening vehicles stationed at a storage yard nearby.
Firefighters stopped the fire at a half-acre with only minimal damage to some scaffolding at the storage center, SDFD said.
There were no injuries or evacuations.
The cause of the fire was not known.
