A new outdoor warning system in Berkeley will use a wailing siren tone and voice message to prompt the public to seek emergency information, details of which will be on the city’s emergency map and alerting systems.
The siren and voice message would signal that people in some or all parts of Berkeley should take emergency action, which would differ depending on the situation.
A wildfire might prompt a message to evacuate part or all of the Berkeley Hills. A tsunami message would direct people to get onto land, away from the marina and the shoreline of the San Francisco Bay.
A different emergency warning might tell a neighborhood to shelter in place.
People in unaffected areas should also stay up-to-date with real-time emergency notifications. An evacuation for one neighborhood might require others to stay off the roads.

Berkeley warning system was built to be flexible
Atop buildings across Berkeley — from the marina to the hills — the warning system is intended to be a new layer of emergency notification that will reach people outdoors.
The goal is to amplify Berkeley's primary emergency tools while being flexible enough to respond to a variety of disasters, be it a tsunami or wildfire.
The new sirens were made possible by Berkeley voters’ passage of Measure FF in 2020. After a period of study and assessment, installation started earlier this year. The siren system is tied to the PG&E grid, and it also has a solar-powered battery backup that can be activated by landline, cellphone, computer or satellite.
To date, 10 sirens have been installed. The remaining five are projected to be installed by early 2024.

Know how to evacuate safely
Knowing information is only one step. Take the required action.
For those who live near wildfire zones or in the hills, use our step-by-step Fire Weather Planning Tool as a guide. You’ll document where you’ll stay and who in your house needs help, create a go-bag, and determine how you’ll evacuate — including two routes by foot and two by car.
When the siren sounds, a plan will help you protect yourself and your household.
The successful evacuation of entire neighborhoods depends on as many people as possible doing their part and following the guidance from AC Alert and Berkeley’s emergency map.
