Up to 2 inches of rain fell over the weekend on parts of the Greenwood fire, which now stands at 14% containment, a key milestone in stopping its rapacious spread.
That figure could further improve Sunday as firefighters took advantage of the weather, working directly on the fire perimeter, said Clark McCreedy, public information officer with the team managing the fire.
The team's meteorologist tracked between 1.25 and 2 inches of rainfall Saturday and early Sunday over the 26,000-acre blaze.
"There is a palpable sense of relief," McCreedy said Sunday. "All that rain helps to extinguish existing hot spots."
It also aids crews deepening the containment line, he said, working within a shovel's length of one another, turning over logs, burying ashes and hunting for heat.
The containment, along the northwest corner of the fire line, signals officials' confidence the fire will not cross that threshold. Hundreds of workers stretching around the fire's perimeter are now working to fortify the rest of the fire line in Superior National Forest.
Crews are clearing fallen trees along Hwy. 2, hoping to fully contain the fire's western border and keep the road clear for passage. On the southeast corner, crews are looking for areas to hold the line, either along Hwy. 1 or the Stony River, to protect the town of Isabella.
The fire, believed to have been started by a lightning strike, has destroyed 14 residences and 57 outbuildings and is a threat to more, according to the U.S. Forest Service.
