4 Reasons Why the Outdoor Warning System Could be Activated


Outdoor Warning Sirens are designed to alert people who are outside to seek shelter inside. In hazardous conditions, Plano's sirens will sound for 3 minutes. During monthly tests, Plano's sirens sound for 1 minute, followed by a voice saying "test."

Sirens are activated for:

1) Tornado warning issued by the National Weather Service
2) Trained weather spotters identify a tornado forming in or near Plano
3) Hail greater than 1.5"
4) Severe thunderstorm warning with winds greater than 70mph.

What should you do if you hear a siren? Go inside and seek more information.
