Johnson County is a
Outdoor Warning System
When Sirens Sound.........
Persons hearing the outdoor warning sirens should seek shelter, obtain additional information from local radio, television and NOAA Weather
Radio and then take appropriate action for their safety.
During severe weather the Outdoor Warning Sirens are activated for
Tornado Warnings issued by the National Weather Service or when a
tornado is observed by a public safety official.
To receive severe weather warnings when indoors, we recommend a
NOAA Weather Radio with Specific Area Message Encoding (SAME),
tone alert and battery backup.
Remember: When Sirens Sound: Take Cover – Tune In – Take Action.
SIRENS ARE TESTED ON THE FIRST WEDNESDAY OF EACH MONTH.
IF UNABLE TO TEST THE FIRST WEDNESDAY, THE TEST WILL BE
CONDUCTED ON THE SECOND WEDNESDAY AT 10 AM.
The fastest, most accurate and reliable means of receiving severe weather information is through a NOAA (National Oceanic and Atmospheric Administration) Weather Radio with a tone alert feature and battery backup. Weather radios may be purchased at local electronics stores.
NOAA Weather Radio is operated directly from the National Weather Service office out of Pleasant Hill Mo, which provides coverage for Johnson County. The weather radio tone alert is activated when weather watches and warnings are issued. Newer models are capable of warning you only if severe weather is expected to reach Johnson County. This feature is called Specific Area Message Encoding (S.A.M.E.). The Johnson County EMA staff would be happy to assist in programing your weather radio.
