The nearly 2,000-acre Cocos Fire that leveled 36 homes and one business in the San Marcos area was 98 percent contained Thursday morning and authorities said full containment was likely by the end of the day.
A Cal Fire tweet stated the fire was 99 percent contained, but the agency's website shows containment at 98 percent.
The fire broke out near Cocos Drive, south of Highway 78, about 4 p.m. May 14 amid gusty winds, triple-digit heat and extremely dry ground cover, according to Cal Fire, which had about 100 fire personnel assigned to the incident as of Thursday morning.
The cause of the fire remained under investigation.
The fire forced thousands of North County residents from their homes but no one was injured. All evacuation orders were rescinded by Sunday.
Among the structures destroyed in the blaze were 25 structures at the Harmony Grove Spiritual Association, a century-old church retreat, according to fire and county officials.
The fire's cost to date was more than $5.7 million, according to Cal Fire.
