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 sirens will initially sound for three minutes but may be activated multiple times if a 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.
