Siren

A severe weather warning siren.

Warning sirens are meant to alert people who are outdoors to seek shelter. They are designed to sound for a maximum of 15 minutes and may not always be heard indoors. The sirens sound when the National Weather Service has issued a tornado warning, or in the event of wind speeds in excess of 70 mph or hail at least 2 inches in diameter. 

Denton has 19 outdoor sirens in service and will be installing three more sirens this year — at Guyer High School, Briarwood Park (near Unicorn Lake) and Fire Station No. 7 (Vintage Boulevard), according to Ryan Adams, city spokesman.  

Once sheltered indoors, residents can get additional information and directions from the National Weather Service via a NOAA weather radio. Adams also encourages residents to sign up for CodeRED alerts via the city's website, cityofdenton.com. The alerts come through phone calls, text messages or email — your choice — and are based on the weather service's warning data.
