A wildfire burning outside Silverthorne has prompted evacuations Monday evening, emergency management officials said.

The Summit County Sheriff’s Office issued mandatory evacuations for the Hamilton Creek neighborhood, which contains roughly 291 homes, while Angler Mountain Ranch is under pre-evacuation notice.

The Ptarmigan fire is burning between 25 and 30 acres, Sheriff Jaime FitzSimons said during a Monday evening news conference. Evacuees are unlikely to be able to return to their homes Monday night, the sheriff said.

The Red Cross is setting up a shelter for evacuees at Summit Middle School, 158 School Road in Frisco.

Fire officials expressed optimism during Monday evening that favorable weather will prevent the fire from growing rapidly.
