Alert Warning System


Integrated Public Alert & Warning System (IPAWS)

During an emergency, alert and warning officials need to provide the public with life-saving information quickly. The Integrated Public Alert and Warning System (IPAWS) is a modernization and integration of the nation’s alert and warning infrastructure and will save time when time matters most, protecting life and property.

Federal, State, territorial, tribal, and local alerting authorities can use IPAWS and integrate local systems that use Common Alerting Protocol (CAP) standards with the IPAWS infrastructure. IPAWS provides public safety officials with an effective way to alert and warn the public about serious emergencies using the Emergency Alert System (EAS), Wireless Emergency Alerts (WEA), the National Oceanic and Atmospheric Administration (NOAA) Weather Radio, and other public alerting systems from a single interface.

Wireless Emergency Alerts (WEA)

During threatening emergencies in your area, authorized government agencies can send Wireless Emergency Alerts to your mobile device. Messages regarding extreme weather, life threatening emergencies, AMBER alerts, and Presidential Alerts during a national emergency are all sent through the WEA system. Visit fema.gov for more information on WEA.

Emergency Alert System (EAS)Alert system sign

The Emergency Alert System is a national public warning system that requires TV and radio broadcasters, cable television systems, wireless cable systems, satellite digital audio radio service providers, direct broadcast satellite service providers and wireline video service providers to offer to the President the communications capability to address the American public during a national emergency. The system also may be used by state and local authorities to deliver important emergency information such as AMBER (missing children) alerts and emergency weather information targeted to a specific area.

The FCC works with the Federal Emergency Management Agency and the National Oceanic and Atmospheric Administration's National Weather Service to implement the EAS at the national level. Only the President determines when the EAS will be activated at the national level, and has delegated the administration of this function to FEMA. Accordingly, FEMA activates the national EAS, and directs national EAS tests and exercises. The NWS uses the EAS on a local and statewide basis to provide the public with alerts and warnings regarding dangerous weather and other emergency conditions.

The EAS allows participating providers to send and receive emergency information quickly and automatically, even if their facilities are unattended. If one link in the system for spreading emergency alert information is broken, members of the public have multiple alternate sources of warning. EAS equipment also provides a method for automatic interruption of regular programming, and in certain instances is able to relay emergency messages in languages other than English.

Along with its capability of providing an emergency message to the entire nation simultaneously, the EAS allows authorized state and local authorities to quickly distribute important local emergency information. A state emergency manager can use the EAS to broadcast a warning from one or more major radio stations in a particular state. EAS equipment in other radio and television stations, as well as in cable television systems in that state, can automatically monitor and rebroadcast the warning.

Additionally, EAS equipment can directly monitor the NWS for local weather and other emergency alerts, which local broadcast stations, cable systems, and other EAS participants can then rebroadcast, providing an almost immediate relay of local emergency messages to the public.

Telephone Emergency Notification System

In an effort to quickly communicate information on impending dangers, the San Bernardino County Sheriff and Fire Departments send high-speed mass notifications via telephone and text messages. This system is known as the Telephone Emergency Notification System (TENS).

The County uses a database of landline telephone numbers, which is updated every six months, to send emergency messages to landline phones only. By signing up below, residents can also receive emergency text messages on their cell phones, add voice over internet phone numbers (V.O.I.P.), and manage their own account using a valid email address. Those without internet connections can sign up by calling 2.1.1 or 888.435.7565.

TENS alerts do not generally go out to the entire County but instead are targeted to affected areas. You must enter a valid San Bernardino County address. This is the address for which you will receive alerts.
