Outdoor Warning Sirens

The City of Grapevine operates fourteen solar powered outdoor warning sirens to notify residents and visitors of potentials hazards, weather, and other emergencies. The system is Outdoor Warning Siren operated by the Grapevine Fire Department and sirens are strategically located throughout the city to provide alerts.  

When the sirens sound, you should move indoors, take cover, and monitor local television, radio, or official social media sources. The sirens will initially sound for three minutes, but may be activated multiple times if the severe weather threat continues. By monitoring the situation, individuals can make informed decisions and know when it is safe to leave your designated safe room.   There is no all clear siren activation.

It is important to note that the Outdoor Warning sirens are not designed nor placed to be heard in your home or other indoor locations.

Sirens will be sounded given one of the following conditions:              

  • Tornado Warning has been issued for Northeast Tarrant County and storm will be impacting the City of Grapevine.
  • Tornado has been spotted by a trained weather spotter
  • Severe Thunderstorm Warning with destructive winds in excess of 70 mph
  • Hail one inch or larger in diameter
  • Sustained wind speeds of 55 mph or greater
