Officials lifted evacuation warnings as firefighters made some progress containing a wildfire near the Jurupa Valley that ignited Thanksgiving Day.

By Saturday, the Canyon Crest fire had spread to about 284 acres since it was first reported south of the Riverside and San Bernardino county line, according to Cal Fire.

More than 200 firefighters have battled the blaze, which is now 50% contained, officials said. Containment refers to what portion of a wildfire’s perimeter has been surrounded by a natural or human-made control line.

The progress led officials to cancel evacuation warnings in Jurupa Valley. The cause of the fire remains under investigation.

Evacuation warnings were initially issued last night as some houses had reportedly burned. The fire as of Thursday evening encompassed 84 acres and was 0% contained overnight, in the area east of County Village Road and west of Sierra Avenue.
