Firefighters have gained the upper hand on the Glass Fire, which has burned 67,484 acres.

The number of single-family homes destroyed between Napa and Sonoma counties now tops 600. CAL FIRE said 308 of those were in Napa, with 334 in Sonoma. Over 150 homes have been damaged by the destructive fire across both counties. An estimated 356 commercial structures have been destroyed.
The cause of the fire remains under investigation.
The fires triggered evacuations for four days in a row starting September 27, forcing tens of thousands of people in Napa and Sonoma counties, including parts of Santa Rosa, St. Helena and the entire city of Calistoga. Nearly 70,000 people evacuated in Sonoma County alone.
Justin Delbridge packed up his Santa Rosa apartment on the morning of September 28 after a night of little sleep. "Sirens everywhere," he said. "There are fire trucks, there are ambulances, police cars, everything. Pretty much everything’s blocked off. There’s a huge file of traffic going down the street of people just evacuating."
"I was up all night anyway, I was watching the fire all night," one Calistoga resident told KCBS Radio after she was evacuated by a wakeup call that came in the middle of the night.
"They came by about six and we weren’t getting the Nixles because the cable’s down and the Wi-Fi’s down," said Calistoga resident Prudence, who boarded a Napa city bus shuttling evacuees. "So they came and told us the shuttles would come and everyone needed to leave."
"We just grabbed a couple items and jumped in the cars and left," said Ron Felcher of Angwin, who spoke to KCBS Radio's Jeffrey Schaub at the evacuation center. "You could just see the whole mountainside, flames climbing up the whole mountainside there. It caused some anxiety just looking at all that."
A structure at the Fairwinds Estate Winery in Calistoga has been destroyed and the Chateau Boswell winery in St. Helena has burned. The Black Rock Inn on the Silverado Trail in St. Helena has also sustained extensive damage.
There has been significant damage across the small community of Deer Park.
There is still no word from Adventist Health on when its hospital in St. Helena can reopen after it was evacuated in the early stages of the fire.
