The Line Fire once again released a massive plume of smoke into the air Sunday in what fire officials described as an expected flareup.

New evacuation orders have been issued for the community of Seven Oaks in the San Bernardino Mountains, which is under threat from the more than 40,000-acre Line Fire burning since the beginning of this month.

Residents were ordered to evacuate from Seven Oaks, a mountain community south of Big Bear Lake and north of Highway 38, the San Bernardino County Sheriff’s Department said Sunday afternoon. Emergency personnel were actively working in the area and firefighting aircraft were on order.
