CALIFORNIA - The LNU Lightning Complex fires have burned 373,920 acres and are 55% contained as of 7:33 p.m. Saturday, August 29, 2020.

256 structures have been damaged and 978 structures have been destroyed, according to CAL FIRE.

"Extreme fire behavior with short and long-range spotting are continuing to challenge firefighting efforts," said Cal Fire. "Fires continue to make runs in multiple directions and impacting multiple communities."

Currently, there are evacuations in Napa, Lake, Solano, Yolo, Colusa and Sonoma counties as nearly 600 personnel battle the flames.

Travis Air Force Base has also issued mandatory evacuations for "non-mission essential personnel and their family members."
