Rough fire expands to nearly 80,000 acres burned

The Rough fire, which has been burning for more than a month, has scorched 79,973 acres and remains at 25 percent containment, the U.S. Forest Service said Wednesday.

About 1,900 fire personnel are working to extinguish the massive blaze, which is now the largest wildfire burning in California.

Unhealthy air conditions are expected in low-lying areas as smoke is expected to remain in drainages until Thursday afternoon, the U.S. Forest Service said. Smoke is expected to settle Wednesday night into Kings Canyon and low-lying areas near the fire such as Hume Lake and Cedar Grove.

There are no evacuations or evacuation warnings currently in effect, the U.S. Forest Service said.

Wildfire managers said Wednesday that the fire is on the north side of Highway 180 about two miles from Cedar Grove, at the east end of Kings Canyon. Vulnerable structures in Cedar Grove have been wrapped and hose lines are down in case the fire reaches Cedar Grove. Meanwhile, firefighters are trying to push the fire away from the lodge area and toward Stag Dome.
