(Description from 72hours.org)
The City's Outdoor Warning System is designed to alert residents and visitors of San Francisco about possible danger. Specific emergency announcements can be broadcast over any one of the 65 sirens which are located on poles and on top of buildings throughout all neighborhoods in San Francisco, Treasure Island, and Yerba Buena. They are tested at noon every Tuesday.

During the weekly test, the siren emits a single 15 second alert tone, similar to an emergency vehicle siren. In the event of a disaster, the 15 second alert tone will sound repeatedly for 5 minutes

If you hear the siren at a time other than its regular test on Tuesday at noon:

Stop what you are doing.
Stay calm.
Listen for possible voice announcements.
Turn on the radio or television, (such as KCBS 740AM, KQED 88.5 FM) for important information provided by the City.ยท
Avoid using the telephone. Do not call
9-1-1, unless you have a life-threatening emergency.


When autoplay is enabled, a suggested video will automatically play next.
