All residents and staff from an Atria Senior Living community in Paradise, CA, were reported safe and accounted for Thursday during a wildfire that began in the morning and by the evening had swept across 20,000 acres, destroying up to 1,000 buildings and causing multiple injuries and fatalities, according to authorities and local media accounts.

The so-called Camp Fire reportedly began around 6:30 a.m. local time and spread quickly to due strong winds; no cause has been reported. By Thursday evening, containment was 0%.

Acting California Gov. Gavin Newsom declared a state of emergency for Butte County, the county sheriff’s office issued a mandatory evacuation order for Paradise and nearby towns, and the National Weather Service issued a “red flag warning,” its highest alert, “issued for weather events which may result in extreme fire behavior that will occur within 24 hours.”

As many as 15,000 structures are threatened, the California Department of Forestry and Fire Protection said.

On its Facebook page on Thursday morning, Atria Paradise, which offers independent living, assisted living and memory care, posted that all residents had been taken to other Atria communities in the Sacramento, CA, area. “Rest assured, we have made all the necessary preparations to keep our residents happy, comfortable, and most of all, safe,” the post said.

The community said it would call family members to let them know exactly where their loved ones were and planned to post updates and respond to messages sent via Facebook. The community also posted a message on its website.

Another senior living community in Paradise, Feather Canyon, managed by Hawthorn Retirement Group, posted Thursday on its website that all residents and staff had been evacuated. The independent living community listed telephone numbers for family members to call for more information.

A 96-year-old resident of Feather Canyon was missing for several hours on Thursday after evacuating in a stranger’s car in the morning, SFgate.com reported. At least seven residents from Feather Canyon were taken to Prestige Assisted Living at Oroville, Oroville, CA, Thursday night, Business Manager April Kale told the media outlet, but resident Marcia Hamilton was not one of them. Hamilton later was found safe in Yuba City, CA, the Laredo Morning Times reported.

At least one other senior living community in Oroville was accepting “busloads of evacuees,” Kale said.
