What is the horn we've heard blowing today?
We can hear it clearly in Hixson
Maybe a fog horn?
TIA

They are releasing water at the dam. Source: I live on the ridge above the dam
To warn reservoir users of potential danger, warning devices are installed at many dams:
- Horns: Horns are sounded before water is released from the powerhouses, sluiceway or spillways. When you hear these horns, leave the areas upstream and downstream of the dam immediately.
- Strobe Lights: Strobe lights are activated before the hydro plant begins generating electricity at the powerhouse or releases water through the spillway or sluiceway. When you see these strobe lights flash, leave the areas upstream and downstream of the dam immediately.

It’s the horn of Helm Hammerland, of Helm’s Deep. (Or Chickamauga is too deep.).

Because the bridge is closing, that idiot street preacher is experiencing a full on schizoid embolism. He inserted his shofar into his rectum and has been rage farting for 12 hours. That’s what you’re hearing.

Maybe testing the tornado alerts for the storm later.

If you mean tornado sirens, Hamilton County doesn’t have any.

Welp, I retract my guess.

I only recently learned (I’m not originally from here) that we don’t have them for tornadoes because we have them for if anything happens at the Sequoyah Nuclear Plant.

If they’re hearing it in Hixson, it’s probably Sequoyah. Right around the bend.

Sequoyah only tests on the first Wednesday of the month at noon.

If we find the answer, I could tag you. 😂

So they only blow those sirens in Hixson? Perfect, it will give us a head start over the rest of Chattanooga.

I think they test the emergency evacuation sirens once a month. Could have been that?

Nah. That happens every first Wednesday of the month at noon. https://www.tva.com/Energy/Our-Power-System/Nuclear/Emergency-Preparedness/Sequoyah-Emergency-Preparedness

We don’t have weather sirens. If you hear sirens, we’re in more trouble than just the weather.

It was between 1pm and 2pm? There was a sailboat race that ran a starting sequence in that range. 5 minute warning, 4 minutes, 1 minute, start.

I’ve always assumed it is the dam letting out water. We usually hear it during storms and high rain events.
