The fire began around noon Saturday north of Jamestown, according to Gabi Boerkircher, spokesman for the Boulder Officer of Emergency Management. Close to 900 homes are in the evacuation area, a tweet from the Boulder Office of Emergency Management said Saturday night.
Jamestown is located at the foot of the Rocky Mountains, about 14 miles northwest of Boulder and about 70 miles northwest of Denver.
The fire is being pushed southeast by wind, Boerkircher said.
“We are asking people pretty much anywhere in this area to be sure they are making an evacuation plan,” Boerkircher said, adding that a local disaster declaration was signed around 6 p.m. 13.30 local time in response to the fire.
Evacuation to Jamestown has been ordered, and pre-evacuation orders are in place in areas south of the city, Boerkircher said.
No deaths or injuries have been reported and a cause of the Calwood fire has not yet been determined, Boerkircher said.
