Border 2 Fire initially started 1:58 p.m. Jan. 23 in San Diego County. After being active for three days, it has burned 6,625 acres. A fire crew of 2,413 effectively contained 10% of the fire by Sunday morning. The blaze's cause remains under investigation.

The fires come as San Diego County mountains and valleys, along with other parts of Southern California, remain under a red flag warning.

Less than two weeks after the Los Angeles County fires wreaked havoc, San Diego County was met with multiple brushfires.

A new wildfire was reported today at 5:58 a.m. in San Diego County. The wildfire has been burning on private land. At this time, there is no data on the containment status of the fire and the cause has yet to be determined.

The last time it was this dry in January, there were barely more than 500 people in San Diego. The year was 1850, and only a quarter-inch of rain had fallen in six months. It made the region ripe for wildfire — but that wasn’t much of a concern. The city’s population was clustered along the coast, far from the backcountry, where most fires burned.
