Firefighters were getting the upper hand on the Canyon Crest Fire, burning between Jurupa Valley and Fontana. As of Saturday morning, fire officials said the brush fire had burned 284 acres but is 50% contained.

Authorities say those who require additional time to evacuate and those with pets and livestock should leave immediately.

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.
