SAN DIEGO (FOX 5/KUSI) -- The Santa Ana winds has kept fire crews on their toes as two brushfires broke out in San Diego County Tuesday. One fire started at 4 a.m. in Ramona, surprising many residents. Fire crews scrambled to contain the blaze because it was dark outside. It was left to the ground crews to hold the line. Luckily, the fire hit a natural fire break and Cal Fire was able to get their arms around the Ramona fire quickly. Across town in Dulzura, another fire broke out along the border. The dangerous topography and the Santa Ana winds complicated firefighters’ ability to stop the flames.

We did have to ground our air tankers a little bit, but we did have rotor wing helicopters that did drop water,” said Capt. Mike Cornette from Cal Fire. The fire in the Dulzura spread to 24 acres until forward progress was stopped by hand crews. While knocking down the border fire, two firefighters were injured in the midst of working the line when a reported rock came loose. One crew member had serious injuries and the other had minor. Both were taken to Scripps Mercy Hospital for treatment. The incident shows the danger of wildland firefighting, even when getting the upper hand. Cal Fire crews are now looking for what comes next. As for conditions, Cal Fire says they are keeping a close eye on the hillsides.
