We strongly urge you to purchase a NOAA Weather Radio for your home and business. A radio that is designed to receive broadcasts from the local National Weather Service office. This is the best source of “Indoor Warning" you can have.
It's best to receive information through many sources so that you get the alert through at least one method (radio; cell phone- apps, phone calls/texts; or landline) during an emergency.
When are the sirens activated?
The National Weather Service issues a Richardson area Tornado Warning or Severe Thunderstorm Warning when destructive winds are at or above 70 mph.
Trained storm spotters have reported a tornado with the potential to affect Richardson.
Golf ball size hail (1.75 inches in diameter) is imminent.
Deemed necessary by City of Richardson officials (i.e. in the event of any emergency when officials need to get citizens to move indoors for their safety).
Who can I call about the Richardson siren system?
Emergency Management Staff is available to address your questions at 972-744-0903.
Should I hear the siren sound in my building or house?
It depends on your location to the siren; however, if you do not hear them indoors it does not mean the system is functioning improperly.
Sirens are not designed or intended to penetrate structures for indoor warning. The purpose of the system is to get the attention of citizens who are outdoors so they will go indoors to seek shelter and further information regarding the emergency. The nearer you are to a siren, the more likely you may hear them inside a business or residence but severe weather (like high wind) will impact the audible sound. For indoor warnings, a NOAA Weather Radiois recommended.
If I hear the sirens, should I call 911?
Only if you have an emergency. Please do not use 911 to ask questions about the system, all questions may be directed to the Office of Emergency Management.
Are 22 sirens enough to have citywide coverage?
The sirens cover 100% of the City.
What do I do when I hear the sirens?
When you hear the sirens take cover immediately in a small room such as an interior bathroom or hall closet. Cover your head.
If you are in a large building go to the most interior portion of the building. Close all doors and staying away from exterior windows and doors. Monitor the radio or television if possible.
When are the sirens tested?
The sirens are tested on the first Wednesday of every month at noon.
