9/15 UPDATE 12:39 p.m.: Fires burning west of Southwest Riverside County are located on Camp Pendleton.
According to base spokesman 1st Lt. Ryan Welsh, the blazes burned in the Whiskey, Zulu and Quebec impact areas.
Friday evening crews were mopping up the blazes, but around the same time another blaze was reported in the Wilcox range, located in the southern-central region of the base.
On Saturday base officials reported residents should expect more smoke today as fires continue to spark from the training. Smoke has been visible from the west most of the day.
Camp Pendleton artillery units are conducting day and night training Friday and Saturday using about 25 Howitzer 155mm cannons.
Welsh said there are no injuries and no threat to structures from any of the blazes.
"Camp Pendleton Fire is monitoring the fires," he said.
Welsh could not provide a containment time, but stressed there is no threat to structures.
The training exercises are expected to last through midnight tonight.
