No need for alarm — the sirens you'll likely hear blasting at 9:50 a.m. today are part of the 2012 Statewide Tornado Drill.
The siren test consists of sirens on for three minutes, then three minutes silent. This cycle will occur four times. The drill is dependent on the weather forecast recommendation of the National Weather Service (NWS).
As of Tuesday afternoon, the National Weather Service had predicted no severe weather for Northeast Ohio.
For additional information on the drill and Severe Weather Awareness Week, see the Ohio Committee on Severe Weather Awareness.
I know because I'm responsible for initiating a few of these 'monthly tests' throughout each calendar year that is sent to & re-transmitted on most of the TV & radio stations in the Cuyahoga/Lorain/Lake/Summit County area.
