Emergency Alert System
The Emergency Alert System (EAS) is a national public warning system to that provides emergency alert messages through local broadcasters, cable, digital radio, and direct broadcast satellite providers. The system is used by local, state or federal agencies to deliver vital information during emergencies such as natural disasters, severe weather, AMBER alerts, and civil emergencies. It is through the EAS that authorities can provide watches, warnings, alert messages, and other vital information during a disaster.
  Passing messages down the branches of an inter-connected network of broadcasters, the EAS system reaches significant portions of the population swiftly and accurately.

NOAA All-Hazards Radio

NOAA Weather Radio All Hazards (NWR) is a nationwide network of radio stations broadcasting continuous weather information directly from the nearest National Weather Service office. NWR broadcasts official Weather Service warnings, watches, forecasts and other hazard information 24 hours a day, 7 days a week.  The NWR is a primary input of information for the Emergency Alert System (EAS) and is the origin of the vast majority of messages.

NWR is an "all hazards" radio network, making it the single source for the most comprehensive weather and emergency information available to the public. NWR also broadcasts warning and post-event information for all types of hazards - both natural and environmental.  NWR does not have to play continuously in the background.  Similar to a conventional alarm clock, the NWR will sound an alert tone when emergency messages are being broadcast.  With one touch of the button, you have access to accurate and timely emergency messages.

In Hall County, NWR messages are transmitted from a local transmitter located in Hamilton County providing a clear signal at 162.4 MHz and provides coverage and alerts for the counties of Buffalo, Hall, Howard, Hamilton, Merrick, Nance, Polk, York, Fillmore, Clay and Adams.

NWR devices (weather radios) are affordably priced at your local department or electronics store.  The Emergency Management Department recommends you purchase a radio that features SAME Coding that will allow you to program a county-specific code and avoid unnecessary alerts.  For the local transmitter, those codes are:

Local Radio & Television
When the EAS is activated, local broadcasters and cable or satellite providers disseminate watch and warning information through an interruption of programming.  Often, information after the initial message is repeated through scrolling text at the top or bottom, and may even include map displays in the corner of the screen.  Some providers may require you to change to a specific channel to receive this EAS message.  Be familiar with your local media and television provider to understand the method and means that EAS messages are broadcast to you.

Internet, Email, SMS (Text Messages)
The advent of internet, email and text messaging provides countless ways of receiving emergency information.  A simple internet search can produce a list of services that can alert you while at your desktop computer or your wireless device through email or text messages.  Many internet services are free, though messages to your wireless devices will likely carry with them all applicable charges.

Outdoor Warning Sirens
The Emergency Management Department maintains and operates an outdoor warning device system of 39 sirens in each of the incorporated communities of Hall County.  These devices are activated remotely by the Grand Island Emergency Center (GIEC).  No "all clear" signal is given through these outdoor sirens.  Anytime outdoor warning sirens are activated, homes and businesses should seek shelter immediately and monitor local media until the danger has passed.  See our siren map for siren locations and 70 dB range.



Siren Activation Policy: Not Simply for Tornados
Outdoor warning sirens are activated in cases when severe weather or other hazards require residents to seek shelter.  These include:

    1. Tornado Warnings issued by the National Weather Service.
    2. Confirmed tornados or funned clouds by NWS spotters.
    3. Straight line winds confirmed above 75 mph.
    4. Tennis ball sized hail (2.5" in diameter).
    5. Large hazardous materials releases requiring residents shelter in place.

Siren Testing
Hall County tests all outdoor warning devices on the 1st and 15th day of every month at 1:00 pm for one minute.  These devices feature two distinct tones:

Alert (Long) Tone: A long, solid tone is used for weather emergencies on the 1st of the month.

Attack (Warble) Tone: A warble tone which wavers up and down is employed for civil emergencies on the 15th of the month.

Depending on the siren, these devices have a range between approximately 800 and 6200 feet at 70db or more. The effectiveness of any outdoor warning device is influenced by external forces such as noise from wind, rain, hail, and thunder. 

Remember, outdoor warning devices are specifically designed for outdoors and are not an effective or reliable indoor warning device.  Families and business are strongly encouraged to monitor any of the warning systems listed above inside a structure.

As you employ a number of these warning systems, you will find yourself more aware and prepared to take action at the appropriate time.  Be aware by receiving timely information during disasters.
