The only yellow 4003 I can recall was at South County Rec Center on Wells road. I never knew about the ACA sirens.Wish I could have heard one of them. Earlier in the thread FedTB you asked about a model 2. Their was one if memory serves correctly on a fire station in Wildwood on Wild Horse Creek Rd ...

Fed TB, a spotter class run by St Louis County's EM and the wrather service back in 2010. They went through a history of tornados in the area and the response to them by Civil Defense. It was becoming more commonplace for communities to use the sirens after the Palm Sunday outbreak and successful us...

St Louis County's first use in a tornado warning was in January 1967 when an F4 tornado ripped through north county. I would guess some of the municipalities activated as well for the event. In 1982 a bond issue was voted for and passed which consolidated control of all the sirens in St Louis County...

Caseyvilles Vortex is about 1/4 mile west of their city hall near a ballfield. Their may be a second Vortex south of the intersection of I 64 and IL 157.

Some of the chemical plants may have sirens. There is a Kingstar array on top of a building near IL 15 and 255. Only a 3 way set up for a locomotive repair facility. And going north there is a Sentry outside of a fire station in what I believe is Pontoon Beach. It's visible from 270 looking north. S...

Those East St Louis 2001s haven't changed position in years and it's likely that they may never function again. Doomed to rot like the SD10s. Unfortunately, East St Louis has absolutely no money except for the bare essentials. Many of their traffic signals no longer function. Sad situation there. I ...
