The Sunshine Wildland fire was 65% contained as of Tuesday evening, according to an update from the Boulder Office of Emergency Management.
Evacuation orders have been downgraded to evacuation warnings, an updated alert from the agency read.
"If you do not need to come back please stay out of the area," the alert read. "Individuals who return to the area may see smoke and small flare ups of the fire, but should only call 911 if they see fire moving."
Winds remained light throughout the day, which helped firefighting efforts, the agency said. Fire crews will patrol the perimeter of the wildfire overnight.
One home on Sunshine Canyon Drive burned down and another home, on Bristlecone Way, sustained damage, the agency said.
The wildfire broke out Monday in the 2900 block of Sunshine Canyon, the Boulder County Sheriff's Office said. More than 400 people and 167 homes were evacuated Monday night.
The East Boulder Community Center, at 5660 Sioux Drive, opened as an evacuation site Monday evening, but closed at 9:30 a.m. Tuesday as evacuees found alternative places to stay, the Boulder Office of Emergency Management said in an alert. The Boulder County Fairgrounds opened for large animal evacuations, and the Humane Society of Boulder Valley took small animal evacuations, in addition to providing food, water, bowls and crates.
An evacuation warning was issued at 3:30 p.m. Monday for west Boulder between Linden and University avenues, but that warning was lifted at 5:10 p.m. "due to limited fire spread and improving weather conditions," according to a notification to residents.
By Tuesday morning, the fire had grown to 19 acres, and 60 firefighters continued suppression efforts.
Another wildfire burned just before 11:30 p.m. Monday in the 10,000 block of Fourmile Canyon Drive, but was quickly extinguished, the Boulder County Sheriff's Office said in a news release. The fire burned in a yard near a mulch pile and grew to 1/10 of an acre, but no property was damaged, fire officials said.
