GREAT BARRINGTON, Mass.— Rain has slowed the Butternut Fire's growth but it's estimated at about 1,200 acres at this point. 

It's the largest wildfire in the Berkshires since nearly a 1,000 acres burned in Clarksburg State Forest back in 2021. 

"We want to start with some good news. Ground patrols are finding minimal new fire activity since this morning's rains began," the Great Barrington Fire Department posted on its Facebook page at 12:45 p.m..

"We want to reiterate that the rain will not extinguish the fire but it is helping to stop the spread. The weather has also delayed some of the drone operations — as a result we do not have an official size. What we do know — the growth has been minimal."

At 4 p.m., the department reported that it will continue to operate under unified command with support from local, state, and federal agencies. Friday's operations will be scaled back with smaller crews and focused on monitoring and reporting.

Two rumors he dispelled were that the fire did not start at Camp Eisner. Mead said the initial location of the burn has not been identified but it did not start at the camp, which is occupied. Ski Butternut is also not in danger and that fire crews have kept the blaze to a safe distance. 

A section of the Appalachian Trail has been affected and that area shut down. 

Thursday's rain slowed growth and allowed crews to establish strong fire boundaries meaning that swaths have been cut and cleared to create fire breaks — which are holding.

At this time, no homes or structures are in immediate danger.

The fire near Brush Hill Road off East Mountain was first reported Monday evening. On Tuesday, it spread over 100 acres, and on Wednesday, it covered over 1,100 acres, expanding into Sheffield.

The town remains in a state of emergency, as declared by the Select Board on Tuesday, but first responders assure that Great Barrington is not in danger.

Firefighters were dispatched to three locations for concerns of fire extension into homes and in one instance, the fire was allowed to continue in a controlled state to a driveway and self-extinguished.  They are aware of one injury from the fire and urge community members to avoid the area and leave firefighting to the professionals.

"More than 120 personnel are on the ground today fighting this fire," Mead reported on Thursday morning.

He said the day’s rain will help to some extent but will not extinguish the fire, explaining "We will remain on scene for the days and weeks to come."  

At this time, the primary focus remains the protection of life and property, as patrols and alert residents identified some encroaching fire and stopped it in its tracks.

"We have strategically placed structural task forces, prepared to protect homes and property. Although they are staged and at the ready — there is NO immediate threat to residents," the department wrote in the 12:45 update.

"At the same time, crews have been working through the rain cutting fire breaks in the forest to further stop any expansion. Those control lines are holding."

Area residents can expect smoke to linger for the next several days. The Southern Berkshire Public Health Collaborative released guidance for the poor air quality, as it can worsen allergies and cause respiratory infections, especially for those with heart disease asthma, or other lung diseases.

Residents are urged to monitor air quality and symptoms, move outdoor activities inside, wear a KN-95 mask when outdoors, close windows and vents in homes, and use HEPA filters.

Even with recent rains — there is a burn ban in Great Barrington until further notice. Additionally, state officials are evaluating week by week for statewide bans.

"With an immense amount of appreciation, we are not accepting donations at this time. In true New England fashion — neighbors have truly helped neighbors," the department wrote. "We are grateful to the community for once again showing your support."

Mead urged the community to "please please follow the local and state bans on fire, the last thing we need is another preventable fire."
