SAN MARCOS, California -- The San Diego County sheriff says nearly 13,000 new evacuation notices have been issued due to a wildfire.

Sheriff Bill Gore said the notifications are due to a Thursday afternoon flare-up and erratic winds around the Southern California city of San Marcos.

More than 20,000 evacuation notices were issued when the fire broke out Wednesday.

The fire is currently the most dangerous of nine wildfires that have erupted in the area this week. The fire has grown to 1,000 acres (404 hectares) and is only 5 percent contained.
