Someone hit the wrong button when trying to SiTest them...instead they set the whole blasted system off.
St. Louis seems to have a habit of doing this once every few years.
The article from the St. Louis Post-Dispatch:

About 2:30 p.m., the county's emergency management office was conducting a test when someone hit a wrong button, said Mark Diedrich, an emergency management specialist.
"Human error," he said. "The good news is that we know they work. With the number of calls we're getting, we know people are listening to them."
It might be a good time to check out some tips from the CDC in case of a real tornado.
