JEFFERSON COUNTY, Ala. (WIAT) - Tornado sirens: They have been the subject of a lot of controversy lately. What are they really intended to do? Meteorologist Ted McInerney reports on this misunderstood warning system.

Storm sirens are a very familiar sound in Alabama but do you know what to do when you hear them?

"I think they are a way to get people aware that there is an emergency that they need to tune into TV or radio station to see what's going on and see if they are in any danger" said Lisa Bohannon of Fultondale.

"They tell you when the tornado warnings are in effect" said Billy Mitchell of Morris.

"I'm going to find out exactly what's going on and take cover if I need to" said Douglas Collett of Mount Olive.

It was good to hear so many people understand exactly what the sirens are for: Outside.

"The tornado outdoor warning devices as they are.. are part of the warning system...only a small part of the warning system" said Jefferson County Emergency Manager Allen Kniphfen.

There are many ways to get information...the most trusted warning is the NOAA Weather Radio especially if the power goes out.
Check your TV.. and also sign up mobile alerts. 

Emergency managers say the sirens are not just for tornadoes. They are also intended to warn about things like chemical spills or national security threats.
