Northern California wildfire threatens Robert Mondavi Winery

NAPA, Calif. -- Containment on the Nuns Fire in Napa County is growing, but it's now threatening the popular Robert Mondavi Winery in Oakville where flames are inching closer.

The Nuns Fire is progressing to the north, spreading at a moderate rate. The fire is being driven by steep slopes and dry fuel. It has burned more than 48,000 acres. Still a lot of evacuations and road closure are in place.

Wineries like Robert Mondavi are closed.

"I drove up here to see how my winery is doing - where I work. It's very emotional. There are so many emotions right now - everyone there is so concern - emails have been flying with coworkers and our bosses checking in on us - making sure everyone is safe," said Nancy Nessman, a Robert Mondavi Winery employee.

There are still a long list of evacuations and road closures. Some have been lifted, but firefighters warn that conditions are subject to change at a moment's notice.

And a big issue is - even when you're allowed back in, watch out for electrical wires on the ground you should always assume they're live.
