San Diego County officials say the fire began around 2:30 p.m. Friday in Lakeside and has burned about 100 acres. About 10 homes have been evacuated.

The county says air and ground firefighting crews are doing well.

Lakeside is about 20 miles east of San Diego and just west of several rural mountain communities. The area was hit hard by wildfires in 2003.
