San Diego County fire agencies also increased staffing amid Santa Ana wind conditions.
The Cleveland National Forest said Monday it brought in more than 130 firefighters from northern California, Oregon, and Idaho to staff fire stations in San Diego, Riverside and Orange counties.
"Typically, 99 percent of fire starts are kept to under 5 acres thanks to the quick response of our firefighters, but when more frequent fire starts are common, increased staffing allows us to minimize the potential for a large wildfire to occur" Forest Supervisor Scott Tangenberg said in a statement.
San Diego Fire-Rescue has five stations equipped with an engine, ladder truck, and fully-staffed brush truck while dangerous fire conditions persist.

"Our brush rigs are always able to be covered," San Diego Fire-Rescue Deputy Chief Kelly Zombro said. "We just have to un-staff a rig to move over to it. In this case, those rigs are actually covered right now, and they can all go."
The fire weather also comes as temperatures in the region climb.
Monday, parts of San Diego County were listed among hottest places in the U.S.
According to the National Weather Service, the San Pasqual Valley hit 97 degrees while Escondido and Santee each hit 96.
San Diego also hit 88 degrees, marking the hottest day of the year to date.
