Watch: Wildfire threatens California's famed wine country in Napa Valley

Two major wildfires on the West Coast continue to sweep across areas of California and Oregon.

In California, the Pickett Fire in Napa Valley has burned more than 6,800 acres, with only 11% of the blaze contained. Evacuation orders remain in place due to the immediate threat to life in the area, near the state's famed vineyards.

Meanwhile, the Flat Fire in central Oregon has scorched more than 21,000 acres, burning at least six buildings and four homes near the town of Sisters.

Authorities hope cooler overnight temperatures will help slow the fire's spread.
