Each system has a different job
Wireless Emergency Alerts can reach phones in a threatened area without a signup. County systems often give more local detail, but you usually have to register. Utilities use the contact information on your account. A weather radio can keep working when cell service is overloaded or down.
A little overlap is exactly what you want
No one channel is guaranteed to be first, and no alert reaches every device. Make sure emergency alerts are enabled on your phone, sign up with your county and keep your utility contact details current.
- Emergency alerts turned on in your phone settings
- County or city alert registration completed
- Current phone and email on your utility account
- A battery radio or another backup way to get information
Do not make any dashboard your only lifeline
California Signal can help you understand the wider picture. For instructions that affect your safety, keep direct official alerts turned on and follow the agency responsible for your area.
