BONNERS FERRY – The lines held.

Despite the wind, the high temperatures and the low humidity, firefighters successfully protected homes, infrastructure and other at-risk areas from the nearby Upper Smith Fire, Northern Rockies Team 1 officials said.

"Didn't see a lot of growth yesterday despite all the wind," Trevor Unsworth, Northern Rockies Team 1 operations section chief, said in an afternoon update Sunday.

Thanks to fire crews' hard work over the past two weeks, officials were adding "a significant bit of containment" to the fire, estimated on Watch Duty at 40%. The nonprofit app is dedicated to providing real-time information during natural disasters, wildfires and flooding events.

While not on the official map, that update will likely be made Monday, Unsworth said containment now extends to Smith Creek and from Smith Creek to the intersection above the switchbacks on the Long Canyon hiking trail.

"That stuff all withstood the wind event (Saturday) without a whole lot of effort, actually with no effort from the folks on the ground," Unsworth said. "The stuff I've walked in looks super good. It obviously hasn't moved or shown a lot of life in quite a few days."

Unsworth said Northern Rockies officials had previously hesitated to call the area contained because it lacks a physical control line around it. However, natural features in the area, primarily the avalanche chute and Smith Creek, have given "a big favor" to fire crews working the Upper Smith Fire, Unsworth said.

The fire's current footprint reflects nearly two weeks of direct and indirect suppression efforts. Crews quickly contained several spot fires during Saturday's winds, while other areas, including fire that moved into the 2015 Parker Ridge Fire scar south of the existing handline, were aggressively suppressed with helicopter bucket drops.

Northern Rockies Team 1 officials said the fire remained active through the night under downslope winds but stayed within a planned indirect suppression strategy footprint.

Crews spent Sunday continuing to secure containment lines, extinguishing remaining spot fires and patrolling the fire perimeter, with particular attention to the Long Canyon Creek area, the 2015 Parker Ridge Fire scar and other established control features along the fire's eastern edge.

Structure protection resources remain in place to monitor for fire movement and respond as needed.

Northern Rockies officials said cooler temperatures, lighter winds and slightly higher humidity are expected to support suppression efforts today, although the fire will remain active in heavy fuels. Firefighters are also preparing for a return to warmer, drier conditions later in the week.

The fire has burned roughly 2,191 acres since it was reported July 8 following a lightning strike in the overnight hours between July 7 and July 8. There are 355 personnel assigned to the fire, including one helicopter, nine hand crews, 12 engines, 13 water tenders and assorted heavy equipment.

While residents near the Upper Smith Fire remain under "Go" status under the state's Ready, Set, Go evacuation protocol, Boundary County Sheriff Travis Stolley said their status will be evaluated early Monday morning.

"The Rocky Mt. team has asked we give them one more shift before downgrading," Stolley said on the department's Facebook page. "All areas will remain in 'Go' (Sunday)."

Other fires in the region include:

• Porcupine Fire — Located in Bonner County's Porcupine Creek drainage, the fire grew to 10 acres as a result of Saturday's winds.

Air resources continue to conduct water drops while crews scout additional options for indirect confinement of the fire, which was reported July 24. Due to the steep, rocky, and challenging terrain, all direct extinguishment actions (working directly adjacent to the edge of the fire) have been completed. Indirect options include handline, machine line, and natural and man-made features where fire can be held.

• Turner Fire — Located 5 miles south of Copeland, the fire is 100% contained and burned 681 acres. All evacuation levels have been lifted from the fire.
