An explosive wildfire that's spurred mass evacuations in California's wine country has tripled in size, but officials are hoping better weather conditions on Tuesday will allow them to get a handle on the blaze.

Cal Fire said the Glass Fire that's raging through Napa and Sonoma counties has tripled in size, burning at least 42,560 acres while remaining 0% contained as of Tuesday morning.

"The fire has expanded into Sonoma County at a dangerous rate of spread," the agency said late Monday as the wildfire rapidly grew.

Three fires merged and scorched through vineyards and mountains into eastern parts of Santa Rosa. Some 70,000 people are under evacuation orders, including the entire 5,000-plus population of Calistoga in Napa County.

Cal Fire shared a video of what the fire looks like from the air from the north end of the blaze just northwest of the town of Angwin.

The Sonoma County Sheriff's Office said that as of 10 p.m. Monday, over 33,800 people have been evacuated from their homes and another 12,624 are under warning status.

"Although we don’t have a specific number, we know there have been home losses in the burn areas and our collective hearts go out to all who have lost their homes in the fire thus far," the sheriff's office said.

But officials said Monday that deputies trying to get people to leave Sunday night as the fire spread encountered resistance from those weary of evacuating.

Sonoma County Sgt. Juan Valencia told KTVU-TV there have been a few people who stayed behind and might have been burned in some areas.

“When you do get that Nixle [alert] and you hear the high-low siren and the knock on the door from law enforcement telling you it's time to leave, it's time to leave,” Valencia said.

Sonoma County Supervisor Susan Gorin, who lives in the Oakmont area of Santa Rosa, told the Associated Press it took her nearly two hours of crawling along a jammed road to reach safety. She saw three neighboring houses in flames as she fled.

“We’re experienced with that,” she said of the fires. “Once you lose a house and represent thousands of folks who’ve lost homes, you become pretty fatalistic that this is a new way of life and, depressingly, a normal way of life, the megafires that are spreading throughout the West.”
