Officers had estimated the hearth to be roughly 200 acres in dimension Sunday morning, however later mentioned an aerial survey confirmed it had grown in a single day to 189 acres.
The Boulder County Sheriff’s workplace continues to analyze the reason for the hearth. Officers know the hearth started within the northwest nook of the burn space, Smith mentioned.

Evacuation confusion
On Saturday, Boulder officers used two completely different emergency alert methods — which generated two completely different evacuation maps — to warn residents throughout the NCAR fireplace, metropolis spokeswoman Sarah Huntley mentioned.
Officers despatched out alerts by each the Everbridge system — which sends notices to landline telephones and to any cellphone customers who beforehand signed up for alerts — and for the primary time used town’s new wi-fi emergency alert system, which targets cellphones whether or not or not the consumer beforehand signed up for alerts.
Utilizing that new wi-fi system meant some folks acquired evacuation alerts who weren't really at risk, Huntley mentioned. Saturday’s evacuation alert by the wi-fi system went out to cellphones in Louisville, Superior and components of Boulder the place evacuation was pointless, she mentioned.
Boulder officers anticipated the wi-fi alert to exit too broadly — it’s a recognized pitfall of the wi-fi alerts — however determined to make use of it anyway to be able to make sure the evacuation warning reached as many individuals as doable who had been within the evacuation zones, Huntley mentioned.
The Everbridge system, which was used throughout the Marshall fireplace, is extra exact, however can miss folks within the evacuation zone if they don't have a landline and didn't beforehand join alerts, she mentioned.
Officers determined Saturday that “overreach is healthier than underreach,” Huntley mentioned.
“The climate situations and the wind situations had been such that we had issues after we initially arrived that the hearth conduct might be unpredictable and will blow towards town,” Huntley mentioned. “We all know that’s a closely populated space and we felt it was necessary to get the message to as any folks as doable.”
She acknowledged that the broader alerts could make it tougher for folks to evacuate by unnecessarily crowding roads and key evacuation routes.
“It’s at all times a balancing act in a majority of these emergencies,” she mentioned.
The primary pre-evacuation alert went out at 2:48 p.m. Saturday on the Everbridge system, adopted at 3 p.m. by an evacuation order. At 3:14 p.m., the wi-fi alert system was used to alert cellphones within the Desk Mesa space. One other wi-fi alert went out at 5 p.m. for Boulder County south of town limits, Huntley mentioned in an electronic mail.
Utilizing the 2 alert methods on Saturday additionally generated two completely different maps for the evacuation zone, Huntley mentioned.
The Everbridge alert system creates a extra exact evacuation map than the wi-fi alert system, she mentioned. The wi-fi system will be adjusted for extra correct mapping, however that step has not but been finished as a result of the wi-fi system is so new.
“That could be a course of enchancment that can take handbook planning on the again finish,” Huntley mentioned. “What we needed to do on the entrance finish (Saturday) was do our greatest to duplicate the Everbridge space in (the wi-fi alert system) as rapidly as we might. We expect we did a reasonably good job, however we do know there have been some addresses included on one map and never on the opposite map.”

“It was complicated,” he mentioned. “And regarding that we had been on the lookout for necessary data and it wasn’t clear.”
Doub in the end determined to not depart, and as an alternative saved an in depth eye on the climate and wind as the hearth burned. A few of his neighbors packed up some belongings, he mentioned, however he didn’t see anybody really evacuate. As an alternative, the neighborhood watched and waited.
“Essentially the most dependable social media put up I had was looking the window,” he mentioned.
Huntley inspired anybody who receives an emergency alert who thinks they acquired it in error to examine the Boulder County Workplace of Emergency Operation’s web site earlier than evacuating, the place probably the most correct maps and data can be posted.
She mentioned authorities will work to enhance the alert course of, and that town will proceed to make use of each methods as wanted in varied emergencies.
