Tornado Siren Test, Hutchinson, MN 7/1/2009

So whats the difference between Alert and Attack?

Alert is the Flat sounding one, so does that mean.. that a tornado may happen? And the Attack one is the one that sounds slightly more like a Fire Truck... is that the one that means a Tornado is on the ground?

Dates back to WWII. Alert is steady tone, it meant there was a threat of an air raid, turn on a radio for more information. Attack is the up and down signal, it meant planes have been spotted and there is immediate danger.
