As temperatures rose and conditions dried over the weekend, residents of Southern California received a swift reminder of fire season as at least seven fires broke out across the Southland, according to Cal Fire.

Juniper Fire initially started 11:28 a.m. June 30 in Riverside County, California. Since its discovery 27 hours ago, it has burned 689 acres. By Tuesday afternoon, a fire crew of 165 succeeded in containing 60% of the fire. However, the cause is still under investigation.

Cooler temperatures and humidity are helping firefighters fight the fire, which nearly doubled in size since Monday afternoon.
