Updates will continue to arrive slowly in the multiple fires that broke out overnight in Sonoma, Napa, and Mendocino counties, but as morning arrived, we know that the largest of the fires, the still growing Tubbs Fire which spans northern Santa Rosa and appears to have crossed the Sonoma-Napa county line into Calistoga grew from 20,000 acres at 7:30 Monday morning to 25,000 acres as of 11:30 a.m. It still appears to be 0% contained according to CalFire and we do not yet have an official count of structures damaged or destroyed — though ABC 7 has an early reported of 1,500 structures burned in total across the three counties.

The Nuns Fire, which seems to have broken out simultaneous with or shortly after that fire, along Highway 12 in Glen Ellen, quickly consumed thousands of acres and has already damaged or destroyed multiple farms, businesses, vineyards, and homes in the area. (See photos above from Glen Ellen.) ABC 7 has a report from a resident on Sylvia Drive, between Glen Ellen and Kenwood, where he reports at least a dozen homes have been destroyed. The Santa Rosa Press Democrat says that that fire merged with another fire this morning, originally called the Adobe Fire, and is now between 15,000 and 20,000 acres in size, despite reports at 7:30 a.m. that it was only 300 acres.

Another fire burning west of Napa, the Patrick Fire, off of Patrick Road, has consumed at least 3,000 acres. A faster moving fire in Napa County, the Atlas Fire, grew from 5,000 acres to 25,000 in just the last few hours.

PG&E power lines are already being pointed to as potential culprits in the fires, which broke out in some cases many miles apart. As the Chronicle reports, "Electric lines can start wildfires even when they don’t fall, if they become tangled with tree branches being blown by the wind and give off sparks. Utility companies are responsible for trimming trees close to their lines." And conditions Sunday night into Monday morning were ripe for fire due to dry conditions and high winds.

The only positive news is that fire officials have said that the high winds of last night have died down for the time being, but they are expected to kick up again around sundown, meaning that fast containment is vital.

In total, SFGate reports there are now 14 fires burning across eight counties in Northern California, including other fires that were sparked in Butte, Yuba, and Nevada counties. One fire-related death has been reported in Mendocino County, but the speed of these blazes suggests there are more to come.

Cell service in parts of the North Bay remains effected, and power outages are spread across the region.

In recent memory, there hasn't been anything like the wildfires currently burning in these relatively densely populated areas of the North Bay, and several cities and towns are likely to be assessing damages for weeks to come, and rebuilding for years to come, including Santa Rosa and Glen Ellen. The most similar event was the 2015 Valley Fire, which was centered in and around the Lake County town of Middletown, which killed four people and destroyed nearly 2,000 structures. But due to the high wind conditions and rapid expansion of the Tubbs Fire, and the conflagrations in multiple localities, today's fires are being compared to the Oakland Hills firestorm of 1991, which also broke out in October — and the full extent of the damages won't be known for days, at least.

The CHP reports they have had to rescue 42 people via helicopter so far because of the fires.

Major structures and businesses damaged or destroyed include the Hilton Sonoma Wine Country and Luther Burbank Center for the Arts in Santa Rosa, and the Silverado Country Club in Napa.

Update: Governor Jerry Brown gave a news conference Monday morning declaring states of emergency in Napa, Sonoma, and Yuba counties. "This is really serious. It’s moving fast. The heat, the lack of humidity and the winds are all driving a very dangerous situation and making it worse,” Brown said, per the NYT. “It’s not under control by any means. But we’re on it in the best way we know how.”

A map below shows all of the fires burning across the state, and below is a list of evacuation orders. A full list of evacuation centers and road closures is here.

Evacuation orders, via ABC 7:

Fires in Mendocino County have triggered the closure of Redwood Valley and School Way from Hwy 101. Evacuations have been ordered along East Road, West Road, Tomki Road to Canyon Road in Willits, Golden Rule subdivision and Reeves Canyon.

The fire has crossed Highway 101 in Santa Rosa and ignited structures west of the freeway in the area of Kohl's Department Store on Hopper Avenue. Highway 101 has been shut down at Bicentennial. Residents and businesses should evacuate immediately in the areas of Cross Creek Road, Sky Farm Drive, Saint Andrews Drive, all residences north Fountaingrove Parkway and Montecito Heights. The fire is believed to have begun late Sunday night near Highway 128 in Napa County and progressed towards Santa Rosa city limits.

Mandatory evacuations are in place for Partrick Rd in Napa County. They have also been ordered in the North Bay for Porter Creek, Petrified Forest, Franz Valley and Mountain Home Ranch Rd.
