This is video given to me from a resident who was evacuated. Most of the fire is out, but this is what it looked when he left his home. #PittsburgFire @abc7newsbayarea

The evacuation area included homes in the area of: north of Jacqueline Drive, south of West Leland Road, east of Bailey Road and west of San Remo Way, according to the Contra Costa County Community Warning System, which was sent out around 3:20a.m.
Residents say it all happened so fast.
"Like an inferno just like those when you hear people like in Napa. They say it was on the ridge line. So, all of this is open space behind these houses. And, it was just engulfed in flames," said Cecilio Quintana.
Residents waited things out in the parking lot at a nearby Safeway, finally getting word they could go home around dawn.
