“Today is a new day and I expect it to be a day of insulting firefighting,” Larimer County Sheriff Justin Smith said in a Facebook post on Sunday.
Dry conditions and strong winds pushed the fires of Calwood and Cameron Peak east on Saturday. The record-breaking fire from Cameron Peak, which has been burning since August, rose to 203,253 acres by Sunday morning and has been 62 percent contained. The Calwood fire, which broke out around noon on Saturday, rose to 8,788 acres with a 5% hold until Sunday morning. This is the largest recorded fire in the history of Boulder County.
The cold front did not bring heavy rainfall, and firefighters on both fires are preparing for windy conditions on Sunday. Winds are expected to push the fires generally west and northwest.
The aerial firefighting effort in Calwood was delayed this morning due to weather conditions, but Jennifer Bray, a communications specialist in the town of Boulder working on the fire, said the crews hit the fire hard from the ground. The crews will go to assess the damage today of both the fires in Calwood and Mount Cameron, according to the conditions. Bray urged residents to stay away from evacuation areas and refrain from flying drones near fires.
“We know it̵
Firefighting efforts on the Cameron Peak fire are focused on its northeastern edge and on a site fire near Lori State Park. In a Facebook update, Paul Delmerico, chief of the fire’s operations department, said the crews had made good progress overnight and expected to do more on Sunday as cold and humid weather slowed the spread of the fire.
Officials told residents of Lyon, north of Boulder, to prepare for evacuation today. They lifted evacuations to the plains east of the foothills, where a wind-induced spot hit on Saturday. A map of the Calwood fire evacuations can be found here.
