Theoretically: Tornadoes
Reality: Siren Tests

Let me explain, there have been a few tornado warnings in my town in the years I have lived here, I have NEVER heard the sirens sound for a warning. A co-worker who is a fireman told me that if I hear the sirens, run for cover because the Fire Chief only sounds them if we are in the direct path of the funnel.

Oh and a local establishment on the edge of town has a Model 5 on the roof that does a "whistle" at 4:30pm quitting time. Used to be just on Fridays but I think they might do it every day now. Said establishment deals with the mentally handicapped, so I wonder if the siren was originally to warn of an escape.

We have a Modulator in a facility that whilst I've lived in this are for 20+ years I have no idea what it is. I do believe however it is military:

http://goo.gl/maps/gU3g5 Signal unknown.

Another system is a Radioactivity leak warning system at HM Naval Base in Portsmouth due to it being home to the Royal Navy's Nuclear Submarines. It is tested every few months and consists of at least four Carter/Castle Castings sirens which sounds in attack and scares the crap out of people:

I have also read that there is one the other side of the harbour in the RNAD (Royal Naval Ammunitions Dump but (quote) "there isn't anything nuclear there...at all..."

There is also a similar siren at an Ammunitions port in Southampton that is sounded when live ammo is moving in/out/around the port. Attack signal.

Cape May County:
Mainland towns: Fires. Island Towns: Fires, Floods, Evacuations. 90% of the island towns have electronic sirens systems while 90% of inland towns only have 1 mechanical siren at the fire station. However, most towns have enough fire stations that a siren can be heard from any area in the town. Every volunteer fire department still uses sirens for fire calls. Most are not on night timers. 1 diaphone still in service in the county.

There is NO county in our state that sounds sirens for thunderstorm warnings. However, Macomb WILL sound for severe thunderstorms that have potential to produce winds in excess of 70mph. Please stop posting vauge/incorrect/frivolous information!!

I'm in Cape May County right now (Strathmere). They have a Model 2 on the roof of their fire station. Been coming for a long time and I think I've only heard it go off once. Is it active, do you know?
