A wildfire roaring through Southern California has forced evacuation orders for more than 20,000 homes, but so far none have burned.
San Diego's Emergency Operations Center says most of the homes are in the city and northern San Diego County.
The 400-acre blaze erupted Tuesday morning. It's fueled by canyons full of brush and pushed by hot, dry winds. Several schools also have been evacuated.
Another fire north of Los Angeles is threatening up to 200 homes in Lompoc in Santa Barbara County.
A high-pressure system has created dangerously hot, dry conditions around the state, with temperatures far above normal for spring and gusty winds possible through Wednesday.
