SANTA ROSA — Communities in wildfire-prone Northern California have an array of emergency systems designed to alert residents of danger: text messages, phone calls, emails and tweets. But after days of raging blazes left at least 23 dead, authorities said those methods will be assessed.
The fast-moving fires, strengthened by fierce winds and nearly absent humidity, began to burn through Sonoma and Napa counties Sunday night. Counties used a variety of ways to send out warnings, but the alert systems rely on mobile phones, landlines or the internet to rouse residents.
State fire officials Wednesday said that while the current priority is getting people out of active fires, they would be following up on the methods used and whether it was even possible to reach everyone with so little time to react.
"People were in bed, asleep at midnight, and these fires came down on these communities with no warning within minutes," said state fire agency Chief Ken Pimlott.
"There was little time to notify anybody by any means," he added.
In emergencies where a few minutes or even seconds can save lives, the notification systems have inherent blind spots. Not everyone will get the message. Sonoma County uses a service that sends out text messages or emails when an evacuation is ordered, but residents have to sign up to receive them. The county also uses a mobile phone app that can receive messages, but again it requires a resident to opt-in to participate.
The county can also trigger automated emergency calls to landlines in an area threatened by fire, but that would only reach homes with those phones.
The Sonoma County Sheriff's Department said the county's emergency alert service texted thousands of warnings to residents to flee Sunday night. However, nearly 80 cellphone towers were knocked out or badly damaged, officials said.
Some evacuees escaped only when they realized the fire was nearly at their doors.
David Leal was at his home in Santa Rosa about 11:30 p.m. Sunday when strong winds began stirring and he smelled smoke. Growing increasingly anxious, he called a fire dispatcher but was assured that there was no need to worry unless he saw flames. He looked outside and didn't, so he and his wife went to bed.
At 2 a.m., they were jarred awake when a sudden blast of wind knocked a lamp off a nightstand. Leal looked out at neighbors who were packing up to get out. There was never a phone call, or a knock on the door.
"We didn't know what was going on, but just instinct led us to agree on the decision to evacuate," he said.
State Sen. Bill Dodd of Napa said he received an alert Sunday night to evacuate, but by that time he had already decided to get out. His power had kicked off at 10 p.m.
He looked up a hillside by his home and "it was the most incredible fire coming at us," Dodd said. "A lot of it is common sense."
Sonoma County Sheriff Sgt. Spencer Crum was on duty Sunday night when he smelled smoke in the parking lot of the department's headquarters in Santa Rosa. Ducking inside, dispatch calls started coming in about fire in the nearby hills.
He and about a dozen other deputies raced to two rural neighborhoods with sirens blaring and warning residents on their loudspeakers of the fast-approaching blaze. Deputies went door-to-door urging residents to flee.
