Heed the Sirens’ Warning, Say EMA Officials
Sunday's devastating tornado in Joplin Missouri underscores the sudden nature of storms and the challenge that emergency management officials face in sending out warnings.
Only 17 minutes separated the first tornado sirens in the city from the onslaught of the tornado. Champaign County Emergency Management Agency director Bill Keller says the National Weather Service tries to give as much advance warning as possible, and it's up to agencies like his to decide exactly when to set off the sirens.
"A lot of it depends on the past history of the storm," Keller said. "Every once in a while, one just fires up unexpectedly so to speak, like the Joplin (tornado). 17 minutes sounds like a lot of time, but if you don't have a plan on what you're going to do and where you're going to take shelter, that's not very much time."
Keller says sirens go off when a tornado has been visually detected, or if there's other evidence a tornado may be hidden by darkness or heavy rain.
Keller says every household should designate a place to go in the event of a tornado warning, and people in stores and other public buildings need to follow staff instructions when the warning sounds. He assumes that some Joplin tornado victims decided to leave stores and try to beat their storm home in their vehicles, which he says was not a good idea.
