Berkeley emergency info works best with AC Alert and the map
Berkeley residents can pair AC Alert with the city's live emergency map and outdoor warning system, since one method may reach people another misses.
Berkeley uses several warning tools, and each has a different job. AC Alert is the city’s main opt-in alert system. Add the addresses you care about, such as home, work, school, or a relative’s place, so messages can be matched to those locations.
The city’s real-time emergency map is the place to check an active evacuation order, an open shelter, or another mapped incident detail. It is live incident information, not a prediction of what will happen at an address.
Berkeley also uses outdoor warning sirens. If a siren sounds outside a scheduled test, take it seriously, listen for the voice announcement, and check current city instructions. No warning method reaches every person in every situation. AC Alert, the map, sirens, Wireless Emergency Alerts, local radio, and conditions around you are layers, not substitutes for one another.
The calm setup is simple: register for AC Alert, bookmark the emergency map, and make sure everyone at home knows where to look if a message names an evacuation zone or tells them to act.
