Title: Tornado Sirens
Post by: JMoses24 on June 02, 2018, 07:58:56 PM
Does your city or county have an outdoor tornado/civil defense warning siren system? If your city/county does, when do they test the system?

Here in Oklahoma City and surrounding cities, the outdoor sirens are checked with a silent test daily at 7am CT, and the audible tests occur every Saturday at noon CT. Doesn't matter if it's "in season" or not...they get checked. Of course, if severe weather is a threat on a particular Saturday, the audible test isn't done and the daily "silent" test is used to ensure proper operation.

Where I used to live in Cincinnati, Ohio, the sirens are checked monthly on the first Wednesday at noon unless bad weather threatens.

No testing whatsoever in my area of Jersey. We still  have sirens, but they've mostly been used for volunteer firefighters, and those alerts have been replaced by pagers then phone alerts. One town nearby still sounds their siren at Noon daily, just because they've always done it.

If a siren did go off for an emergency, I don't think people here would have any clue what to do.

Pueblo County Colorado only has them near the Pueblo Chemical Depot east of the city of Pueblo, to be activated in the unlikely event of a chemical release. I don't know what their testing protocol is. As you move down the Arkansas River valley, where tornadoes become more likely as you move away from the mountains, you start to see them (La Junta?). I don't think Colorado Springs has them either, but don't know about the Denver area. Denver and north is sort of a mini-tornado alley.

I remember them in the Twin Cities, and I think the test was first Wednesday of the month at 1:00 p.m. When I first moved there in the 1970s, it wasn't possible to isolate the zone that was activated, so our sirens would go off under a blue sky because of a tornado warning for a suburb 20 miles south of us. Later, activation was shifted over to the individual cities. Sometimes, in some cities the sirens would be activated for a strong thunderstorm that didn't have a reported tornado.

In northeastern Illinois, it's the first Tuesday of the month, at 10:00 am.  Everyone looks up when they hear them and checks the clock.

Every Wednesday at Noon (except if the weather looks questionable)

I canít say Iíve ever heard one, but my work is in the middle of nowhere and probably miles from the nearest one.

My hometown had a Civil Defense siren that would get tested often, but I haven't heard it go off since the 1990s.

Ours is tested every Wednesday at 5 PM, provided it's a sunny day.
