AC Alerts help you respond to emergencies
In an emergency, the City will send AC Alert notifications via text message, email, TDD/TTY devices, and phone to let you know what protective actions to take.
AC Alert notifications can include:
- Evacuation Warnings and Orders
- Shelter-in-Place information
- Information about extreme fire weather, flooding, and fires
- Communication during an emergency about evacuation routes, shelters, and transportation
- Other public safety incidents where lives may be at risk
AC Alert is reserved for rare situations when there is an urgent threat or need for the public to take protective actions. Messages will be targeted to people in the areas that need to take action.
In most cases, emergency responders can quickly resolve emergency incidents without the public needing to take action.
Sign up for AC Alert. Stay informed so you can take action to protect yourself and your loved ones in emergencies.
