New Federal Emergency Alert System to
replace EBS
The Federal Communications Commission (FCC),
the National Weather Service (NWS), and the Federal Emergency
Management Agency (FEMA) have issued final implementation
plans for streamlining the nation's emergency warning system
for the twenty-first century. Replacing the current Emergency
Broadcast System (EBS), the new Emergency Alert System (EAS)
has been designed to work effectively with satellite, broadcast
and cable technologies.
New features of the EAS include and NWS
developed digital system architecture that allows broadcast,
cable, satellite and other services to send and receive alerting
information. Multiple- source monitoring for emergency alerts
and a mandated standard protocol for sending messages are
also part of the EAS.
EAS's digital capabilities will also exist
on the next generation of NOAA Weather Radios. Specific Area
Message Encoding (SAME) allows NWS offices to send hazard
warnings to specific geographic areas (counties) over the
NOAA Weather Radio network. A brief digital code at the beginning
and end of each message identifies the type of warning as
well as the geographic area for which the warning is intended.
A decoder on the NOAA weather radio receiver will activate
only those radios within the warned area.
The message encoding technology will also
allow any commercial or cable broadcasters to automatically
receive an encoded warning message and immediately display
it on the air. use of the code is currently limited to time-critical
messages related to public safety, such as weather and flood
warnings as well as civil emergencies.
As part of the EAS announcement, the FCC
notified radio and television broadcasters that they are required
to replace the EBS with EAS equipment by July 1, 1996.
