Cleaning up Tuesday was the focus of Maine Forest Protection Division after at least four fires that were started by lightning strikes from Sunday’s quick-moving thunderstorm.

Fire crews from northern and central areas of Penobscot County had extinguished the flames by Tuesday at sites in Greenbush and Lincoln, an area north of Millinocket Lake, and on the State Road in Millinocket, according to Brian McLaughlin, a laborer with the state Forest Protection Division.

“I haven’t heard of any new ones,” he said Tuesday in a phone interview. “Crews are still out mopping up ones from yesterday.”

Fire crews also were expected to be at the sites Tuesday checking for possible flare-ups and hotspots.
