UPDATE 5:30 p.m.: The cause of a fire in Los Osos that began in a motor home was mechanical, according to a Cal Fire spokesperson.
The fire, fueled by five- to 10-mile-per-hour northwesterly winds, spread to a number of neighboring structures, causing approximately $100,000 in damage, said Es Berliner, public information officer for Cal Fire.
It was not immediately clear what the various outbuildings were used for.
Winds also caused a number of small spot fires in vegetation near neighboring residences, but crews from Cal Fire and the Morro Bay Fire Department were able to put them out before any homes were damaged.
Never miss a local story.
Berliner said the investigation into the fire was still ongoing Tuesday night, but preliminary information indicated that the owners of the motor home had sold the vehicle and were conducting repairs prior to the new owner arriving to pick it up.
The blazes were put out by 2:45 p.m. No one was injured.
