Smoke filling the Lake Tahoe Basin and Truckee areas is from the Owens River Fire burning near Mammoth.

More than 200 people are fighting the blaze that started Sept. 17. While no cause has been given, officials say it was human caused.

It remains at about 6,000 acres and 20 percent containment.

A surge if mid-level moisture is in the forecast for late Tuesday through Wednesday which could result in thunderstorms. While the rain would be good, the threat of lightning strikes is not.
