BURLINGTON, Maine — An incessant wind propelled a wildfire through a home, two barns, two motor vehicles and at least one shed as it consumed more than 50 acres of former hayfields on Long Ridge Road on Wednesday. No injuries were reported, firefighters said.

The fire at 1473 and 1480 Long Ridge Road was among the most damaging of the half-dozen wildfires reported statewide. Fires also were reported in Marion Township, Waite, Long A Township, Soldiertown and Cooper. The Cooper fire, which destroyed about 3 acres, likely was arson, according to Maine Forest Ranger Jeff Currier.

Firefighters from Burlington, Howland, Lincoln, Lowell, Mattawamkeag and Passadumkeag started fighting the Long Ridge Road fire about 1 p.m. Five and a half hours later, they had it about 80 percent under control, Currier said.

“It is continuing to grow, but we have it pretty well corralled,” Currier said Wednesday. “We will work this well into the evening and have a crew here in the morning.”

Homeowner Melissa Bowers of 1480 Long Ridge Road said she was on the second floor of her home baby-sitting her grandchild when she looked across the street and saw a barn at 1473 Long Ridge Road engulfed by flames. Former hayfields also were burning around it. The homeowners there, Michael and Stephanie Howey, were not home at the time, Bowers said.

Bowers called 911, collected her grandchild and her two dogs. By the time she was downstairs, the flames had begun consuming the Howey home, so strong were the winds blowing in the area, she said.

“It just was so fast,” Bowers said. “It was moving across the road and had already started to burn on this side.”

The first firefighters to arrive from Burlington immediately called for more help. Several large patches of Bowers’ front yard were burned, but the fire largely burned a field north of her house. It destroyed a shed and a barn in the backyard before burning close to 50 acres behind her house. The house at 1473 Long Ridge was destroyed, as were a pickup truck and a van, a barn and another structure in a nearby cemetery.

Firefighters protected standing structures before attacking the flames. Three Forest Service rangers and two service helicopters fought the fire in the fields, with the helicopters shuttling water from Eskutassis Pond almost constantly.

“It’s nasty,” Frank Hammond Sr., Burlington’s fire safety officer, said. “The wind and the heat you just can’t fight. You have to work against it, and it is constantly working against you.”

National Weather Service and Forest Service officials will review conditions Thursday morning to determine whether to continue the red flag fire weather warning they issued Wednesday. Tony Mignone, a weather service meteorologist in Caribou, said conditions Thursday likely are to be only slightly less challenging than they were Wednesday.

Wind speeds are likely to hold at 15 to 20 mph with gusts of 25 to 30 mph. Relative humidity should run at 20 to 25 percent in the afternoon, all within or just under typical red flag conditions, Mignone said.

“We don’t have any precipitation in the forecast that would drive the conditions out or alleviate the problem,” Mignone said. “On Friday, we have some low probability of showers in the north. If that occurs, it will lessen things. And also the wind speeds on Friday are predicted to be much less than what we saw today.”

Forest service officials warn residents and motorists to be extremely careful with cigarettes and other burning materials.
