BANNING, Calif. (AP) - Strong winds are fueling a wildfire in Southern California.
    
Flames have raged through 2 1/2 square miles of Riverside County. It's been moving through a largely undeveloped stretch of the San Bernardino Mountains, but it is burning dangerously close to neighborhoods in the city of Banning.
    
Southern California fire officials say the fire broke out just after noon and has been fueled by 29 mph winds.
    
San Bernardino County fire officials say at least 425 firefighters are working to gain control of the fire. Evacuations and street closures are in effect in several neighborhoods to the south of the fire in Banning.
    
If winds from the east continue driving flames westward, the fire could affect communities in Cherry Valley and Beaumont.
    
Much of Southern California is under red flag warnings for fire danger due to winds, low humidity and heat.
