NAPA, Calif. -- Wildfires raging across Northern California have killed at least 17 people as hundreds of firefighters battle the flames and keep thousands of people away from the blaze's path.
Most of the fires were ignited Sunday, driven by winds of more than 50 mph and dry conditions. With no rain in the forecast this week and a chance of gusts of 35 to 40 mph Wednesday, forecasters said the weather will create challenges for firefighters.
More than 20,000 people had been ordered to evacuate as of Tuesday night, and authorities were encouraging others to pack "ready-to-go bags" with documents and medicines in case they had to flee the fast-spreading flames on a moment's notice.
"I think it would be one of the worst disasters in California history," California Highway Patrol Capt. Mike Palacio said at a community meeting. "You gotta be patient. We are just trying to keep people alive."
Wildfires have burned more than 122,000 acres in California. The largest fires were in Northern California's Sonoma, Napa and Mendocino counties, filling the picturesque landscape of the state's wine country with charred rubble and clouds of smoke.
President Donald Trump has signed a major disaster declaration and fire management assistance grants for the state, the White House said.
"The loss of homes and burning of precious land is heartbreaking, but the loss of life is truly devastating," press secretary Sarah Sanders said Tuesday.
Of the 17 people who've died since Sunday night, 11 were in Sonoma County, officials said.
Two of the deaths were in Napa County, county spokeswoman Kristi Jourdan said. Charles Rippey, 100, and his wife, Sara, 98, died when a fire engulfed their home near the Silverado Country Club north of Napa, Jourdan said.
More than 100 people were being treated at Napa- and Sonoma-area hospitals for fire-related injuries or health issues, including burns, smoke inhalation and shortness of breath.
Continuing Coverage: California Wildfires
Families are frantically searching for more than 180 people who have been reported missing. Authorities believe communications issues are preventing many of those people from checking in with relatives.
But one family's search for a loved one in Santa Rosa ended tragically. Christina Hanson, 28, who used a wheelchair and lived in an apartment next to her father's house, was reported missing after the fire. Hanson had called her father's ex-wife to say she saw flames, but no one had heard from her after that, her family said.
After a day of panic and uncertainty, Hanson's cousin confirmed she had died in the fire.
'It looked like we were at war'
The biggest blaze, the Tubbs fire, has reduced cars and homes into burnt piles of ash and rubble in Santa Rosa, a city of about 175,000 roughly 50 miles northwest of San Francisco.
That fire has burned 28,000 acres and destroyed at least 571 structures, Cal Fire said Tuesday, making it one of the top 15 most destructive fires in recorded California history.
A large part of Santa Rosa was evacuated, including the Kaiser Permanente Hospital and Sutter Hospital, where patients emerged from the facilities with protective masks, some using walkers or wheelchairs.
The only thing that remained of Margaret Curzon's house was a concrete statue of the Virgin Mary. She said her parents lost almost everything when the wildfire destroyed their home in the Coffey Park neighborhood.
Her mom woke up early Monday and smelled smoke but thought it was the neighbor's barbecue or chimney, so she went back to sleep. They woke up again because their bichon frise, Brady, was whimpering.
Curzon's father looked outside, and his first thought was that there was some sort of bomb, or an attack.
"It looked like we were at war," Curzon said. "The sky was orange, and there were embers falling from the sky."
