The Apple Fire has burned more than 20,000 acres and has forced evacuations in Riverside and San Bernardino county.
Evacuation orders were issued for mountain, canyon and foothill neighborhoods and residents can search by their address on the county website to see if their area is under any orders.
The fire started on Friday in an unicorpotated part of Beaumont and quickly spread into more populated areas.
The cause of the fire is still under investigation.
