Efforts to contain the fire show in Tuesday's mapping based on satellite fire detection data which reveals a spot 6 miles north of Picketts Junction in the last 12 hours.

There is an indication of some significant fire in that region on Labor Day.
Satellite mapping shows some active fire due north of Luther Pass close to the containment lines this morning. More active is the south edge of the fire north of Strawberry Creek and on either side of the extension near Caples Lake.

National Weather Service forecasters in Reno said that residents downwind of the Caldor and Dixie fires should expect continued poor air quality.
“Smoke will fill portions of the Tahoe Basin and settle into some Western Nevada valleys during the overnight and early morning hours,” forecasters said. “Late afternoon and evening light breezes will pick up today and through the rest of the week, which will help with smoke dispersal and air quality.”
Forecasters said air quality will depend on the fire activity.
