The National Weather Service in Little Rock broadcasts weather information 24 hours a day on NOAA Weather Radio.
When it becomes necessary to issue a severe weather or tornado warning, the National Weather Service can activate an alarm tone. This tone activates specially equipped Weather Radio to alert you that very important information will follow. The advantage is that you do not have to continuously monitor your radio, because it will put out an audible alert.
Since most Weather Radios are portable, you can take them on vacations or other trips. If you are camping, you can hear the latest forecast and information on potentially severe weather.
Weather Radio provides more than severe weather warnings, it provides tailored area forecasts, hourly weather reports, summaries of the past weather, and more. The advantage is that the information you hear on Weather Radio is routinely updated. During adverse weather, along with forecasts and warnings, safety information is broadcast. For example, if a tornado warning has been issued, you may be told what the safest locations are to protect yourself.
S.A.M.E. codes for every county in Arkansas:
You use these codes to program your weather radio for your county. It also lists the frequency the radio should be tuned to in many towns to get the weather radio transmission. These frequencies will work for most, but you should always try a couple near you to see which one sounds best for your area.
Weather Radio broadcasts are originated at various National Weather Service offices nationwide. Each transmitter has a normal range of 35 to 40 miles, but with high quality receiver and antennas, the signal can be picked up at greater distances. One of the goals of the National Weather Service is to expand the Weather Radio network to include nearly every location in the United States.
