RIVERSIDE COUNTY, Calif. — A fast-moving wildfire raged across Southern California Thursday, threatening neighborhoods and forcing people from their homes.

The fire, which was first reported Wednesday, quickly grew from 300 to 10,000 acres by Thursday afternoon according to the Riverside County Fire Department. It covered 15 square miles.

“It’s heart-wrenching. It’s very heart-wrenching,” Joanne Trosper told CNN affiliate KTLA, after watching the fire consume some of her neighbors’ homes in Poppet Flats. “Anytime the fire comes, it’s bad memories, but this is the worst one yet.”
