“As the week goes on we’re starting to expect the fuel conditions to dry up. It’s going to be a little tougher fight as the week goes on,” said a fire official on scene.

Highway 550 was expected to remain open Monday from 8 a.m. to 6 p.m. with traffic restricted to one lane, but because of heavy smoke in the area, the highway was closed about 2 p.m.

There is a forest closure in place for the San Juan National Forest. Visitors can call 970-385-8700 for more information.
