The National Weather Service is warning that hot, dry conditions forecast for Southern California over the next several days will increase the danger of wildfires.
Already, a brushfire near Banning is burning out of control and threatening homes, an official at the Riverside County Fire Department said Sunday.
Monday will be the hottest and driest day, the weather service said, but fire danger was expected to build throughout Sunday, and continue through Tuesday.
