Outdoor Public Warning Sirens Temporarily Out of Service This Afternoon
San Francisco, CA – The Outdoor Public Warning System Sirens throughout the City will be temporarily out of service this afternoon to undergo additional testing to investigate the cause of the activations experienced late last night and early this morning.
The sirens will be deactivated this afternoon while being serviced. During this temporary maintenance window, should there be a need to alert the public of an emergency, the City will leverage its numerous emergency public information resources including the City’s text and email emergency alerting systemwww.alertsf.org, as well as traditional media and social media (via @SF_emergency and @SF72org on Twitter; www.facebook.com/SFDEM andwww.facebook.com/sf72org on Facebook; and on www.Nextdoor.com). Additional emergency public information dissemination strategies that can be engaged if needed include first responders canvassing impacted areas to ensure all are notified.
The Outdoor Public Warning System Sirens will be reactivated after service is concluded. For more information about the San Francisco’s Outdoor Public Warning System visit http://sfdem.org/index.aspx?page=13.
