Early this morning, Grayson County Sheriff's dispatchers noticed the flooding emergency sirens blaring out of control, but the radar was clear and storms were no where to be seen. So why did they sound?
Sirens like the ones that went off in Sherman this morning are meant to be a mass warning system for people who may not be near a TV or radio, but false alarms do happen occasionally.
So when do you know when to react?
"We don't want people to say it's just another false alarm. Turn to your local TV if this was an actual emergency," says Sherman fire Chief Jeff Jones.
Officials were able to turn the alarm off this morning.
Water was the cause of the false alarm. It had shorted the circuit board.
"I think it's a good test of the system. I did hear it. People called. It does work. That’s the good news," says Jones.
Fire officials say the warning sirens are just like any other piece of technology. They do malfunction from time to time. But, that malfunction is not a common occurrence.
The flood siren that activated is located at Sunset, west of Wakefield School.
