Border 2 Fire initially started 2:31 p.m. Jan. 23 in San Diego County. After being active for 20 hours, it has burned 5,389.4 acres, an increase of 1,139 acres since the last update. A fire crew of 692 effectively contained 10% of the fire by Friday noon. 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.

Two brush fires burning along I-15 in northern San Diego County have prompted evacuation orders for some as they burn at high rates of speed due to strong winds in the area.
