Now that the Siren is Gone…
By BJ Kohlstedt, Lake County Emergency Management Director
If you’re used to hearing the civil defense
siren test on the first Wednesday of the
month in Two Harbors, July 6 may be
quieter than usual as the last civil defense
siren in the county is disconnected. This
may be a good thing for some, but might
cause concern for others who wonder how
they will now receive severe weather
warnings.
The Public Alert and Warning System
(PAWS) has come a long way in our
lifetimes. Emergency radio messages
started in 1951, with television joining the Emergency Broadcast System in 1963. But times have
changed, and less than 40% of people now have TV or radio on during the day, with only 5-10%
in the middle of the night. Internet use, including video and email, now ranks first or second for
information gathering at both home and work. Cell phones are increasingly popular over
landline phones, with landlines decreasing at a rate of 3% per year.
In 1997, the Emergency Alert System (EAS)
was designed to send alerts to radio, TV
and NOAA weather radios. These radios
are small, inexpensive, and can be
programmed with Specific Area Message
Encoding (SAME) to target only the local
messages the user wants to hear. They are
still the best way to receive not only
weather emergencies, but other local and
presidential notifications as well. Local
Sheriffs and Emergency Managers can make
use of the system to warn residents and
visitors of hazardous material releases, fire
evacuation orders, or emergency shelter and supply locations, as they did during the ice storm
and power outage of 2009.
In 2006, recognizing the changing media options for public warning, the President signed the
“Public Alert and Warning System Executive Order” stating the US will have “an effective,
reliable, integrated, flexible, and comprehensive system to alert and warn the American
People.” It expands upon the current system to include internet, cell phone and satellite
communication, which can be accessed by local emergency managers and public safety officials
to send immediate threat alerts. All of this is scheduled to be ready by the end of 2011, and the
first ever nationwide IPAWS (Integrated Public Alert and Warning System) exercise is planned
this year to increase public awareness and practice responding.
So, back to the future of sirens in Lake County. We’ve received several quotes for new siren
systems, ranging from $8000 to replace the current system in Two Harbors, to $80,000 to
upgrade and cover our three cities. Most sirens are owned by cities, and Lake County will work
with the city of Two Harbors to explore options. But sirens are a high cost, maintenance heavy
investment, and even the siren experts warn that, “A lot of people think these will wake them
up indoors in the middle of the night and that’s just not the case. These are outdoor warning
systems used to warn people to take shelter indoors.” It’s still recommended that people not
rely solely on outdoor sirens to signal severe weather, but that they keep a NOAA weather
radio with an alert tone in their homes and businesses.
Lake County currently has a Public Alert and Warning procedure under review as part of our
Emergency Operations Plan update. It includes NOAA weather radio alerts, along with media
announcements, use of the Lake Superior School System Instant Alert calling system, ECHO
alerts for non-English speakers, plans for using IPAWS as it becomes available, and use of
mobile speaker systems by law enforcement at public outdoor events and gathering places. We
