The National Weather Service is teaming up with the U.S.
Department of Homeland Security (DHS) to broadcast critical all-hazards messages
via NOAA Weather Radio. Such messages can include warnings of terrorist
strikes, nuclear accidents, toxic chemical spills, and 911 outages. This
will make the radio network into an "All-Hazards" network. However,
weather messages will continue to be the main emphasis on a day-to-day basis.
Upon request by:
New EAS codes are being implemented to assist with
distribution of these messages. If you have a programmable NOAA Weather
Radio receiver (which uses EAS codes to determine the message type), this may
have an impact on the operation of your receiver. If it is an older model,
it may display "unknown warning" or "unknown statement" when these codes are received,
but may still sound an audio alarm. Newer
programmable radios will likely have these codes in place, as manufacturers
prepared for the new codes last year, or likely have the capability of manually
inserting the new codes. Non-programmable radio receivers, which use a
1050 Hz tone for alarm activation, will not need to do anything to receive the
new messages, but be advised the alarm tone is used for any warning in the
coverage area of your local transmitter.

receivers, click here. The following new EAS codes will be available through the
La Crosse NWS weather radio stations. No changes to
individual county codes will take place.

messages will be relayed by NWS personnel over NOAA All-Hazards Radio. These messages will
contain alerting features that can activate alarm-capable radio receivers, as
well as deliver the message over the Emergency Alert System (EAS) for use by
commercial media. With over 900 transmitters nationwide, over 97% of the
U.S. population will have access to such alerts.
