Sonoma County Emergency Services officials say the systems they use to alert residents of disasters have significant issues, nearly a year after the deadly Northern California wildfires prompted criticism about how the county alerted people to the dangers.
The county conducted a test of several alert systems last month and their newly released After Action Report found serious problems with them.
"There is no guarantee at this point that we can get [messages] to everybody at the right time," said Christopher Godley, Sonoma County's Interim Emergency Manager.
In the test, SoCoAlerts, which is an opt-in system that sends messages to landlines, cellphones and emails, successfully delivered the test message to a person or an answering machine 51 percent of the time.
The county did find that the publicity leading up to and after the test increased the number of people subscribed to the SoCoAlert system by more than 30 percent.
